TUTORIAL: GLOVE Architecture integration of GNSS and vehicular communications
Vehicular ad hoc networks (VANETs) are considered as one of the most valuable means for improving road safety and transport efficiency and as an enabler of value-added services for passengers and drivers. With VANETs, drivers will receive information about nearby nodes (also beyond their visual horizon) and about events occurring in the neighborhood: this will represent a concrete opportunity for further improving the driving experience and safety, leveraging ICT solutions. VANETs have already been standardized (international harmonization is still in progress) and undergone field operational tests. Even if they are still being investigated for solving possible issues related to their scalability in the future – when a large number of cars will have been equipped with VANET transceivers – they are ready for day-1 exploitation.
VANETs are expected to have the same impact on driving, as GNSS (GPS) navigators had in the past years, with an ever increasing number of equipped cars. Even more, the availability and reliability of positioning based on Global Navigation Satellite Systems (GNSS) is still improving and, last but not least, new GNSSes are being deployed. In particular, Galileo is the European global satellite-based navigation system, a unique civil system under civil control that will start early services in 2015. By offering dual frequencies as standard, Galileo will deliver real-time positioning with unprecedented accuracy for a publicly available system. Furthermore, Galileo will offer enhanced availability and coverage with respect to other navigation systems. There is no need to wait to the full constellation in order to join the significant improvements, because it is fully interoperable with GPS, the United States’ Global Positioning System
From a conceptual point of view, VANETs and Galileo are just two enablers. GLOVE is a technological STREP project which addresses the mutual benefits coming from the cross-domain integration between the two. The problem is split into three steps, corresponding to the functional blocks constituting the overall GLOVE OBU: a GNSS receiver (OBUg) suitable to receive GPS/Galileo signals and to exploit SBAS (Satellite Based Augmentation System) corrections (e.g. provided by EGNOS or EDAS), integrating also information other than GNSS signals (e.g. from VANET domain); a VANET transceiver/router (OBUv) benefiting as much as possible from both time and space information; a block (OBU^) performing the integration between GNSS and VANET data, expected to improve existing vehicular services and to enable novel ones.

- 10:20 Price Incentivised Electric Vehicle Charge Control for Community Voltage Regulation
- With the growing availability of Electric Vehicles, there is a significant opportunity to use battery "smart-charging" for voltage regulation. This work designs and experimentally evaluates a system for price-incentivised electric vehicle charging. The system is designed to eliminate negative impacts to the user while minimising the cost of charging and achieving a more favourable voltage behaviour throughout the local grid over time. The practical issues associated with a real-life deployment are identified and resolved. The efficacy of the system is evaluated in the challenging scenario in which EVs are deployed in six closely distributed homes, serviced by the same low voltage residential distribution feeder.Presenter bio: Damian Kelly was awarded a PhD in 2010 by NUI Maynooth, Ireland for his research and development of smart home systems to monitor elders to detect cognitive decline.

- 10:40 A Geographical Segment Architecture for VANET
- Equipped with wireless transceivers, vehicles can be connected into a vehicular ad hoc network (VANET) to collect, share and utilize data for a variety of purposes, such as safety, navigation and entertainment. As diverse sensors are integrated into vehicles and large numbers of wireless access points (AP) are deployed within cities, far more data can be collected and utilized to support smarter applications. However, the data explosion puts further strain on the broadcasting and routing protocols which are already challenged by the high mobility vehicular environment. In this paper, a geographical segment architecture (GSA) which clusters vehicles based on their geographic locations is proposed. Leveraging on a two-tier architecture, the GSA can exploit cluster IDs and the infrastructure to implement efficient broadcasting strategies and routing protocols. Simulation results show that GSA based protocols can achieve low delay broadcasting and high throughput routing.

In this paper, a thorough analysis based on real-world project is conducted to evaluate the impact of electric vehicles infrastructure on the grid relating to system load flow, load factor, and voltage stability. University of Southern California (USC) Distribution microgrid was selected and tested along with different case scenarios utilizing the electrical distribution design (EDD) software to find out the potential impacts to the grid.Presenter bio: Zeming Jiang is currently a PhD student in University of Southern California, majoring in Electrical Engineering.

- 11:20 Enabling Location Based Services for Hyperlocal Marketing in Connected Vehicles
- Location based services is a class of computing services that uses the consumer's location data in order to personalize and enable features and services. Services include those for mapping and tracking, emergency response and disaster management and location based advertising. Of these services, location based advertising, also knows as hyperlocal marketing, accounts for the largest market share. In this paper we provide a motivating example of a hyperlocal marketing service applicable to connected vehicles and explore communication architectures for enabling such location based services. The specific scenario we consider uses sensors to automatically detect automotive problems in an intelligent vehicle and share the information wirelessly with a hyperlocal marketing server. The server, in turn, gets a dynamically updated list of hyperlocal services from retailers which would be analyzed, filtered and delivered to the consumer wirelessly so that the consumer could avail of a suitable service to address the issue. While considering different architectures we highlight the lack of a suitable standard for vehicle-to-infrastructure communication and suggest that this area needs further study.Presenter bio: Vishnu Narayanan received his Bachelor of Technology degree in Electronics and Communication Engineering from Amrita Vishwa Vidyapeetham, Kollam, India in 2014.

- 11:40 Coordinated, Progressive Vehicular Headlight Glare Reduction for Driver Safety using Wireless Sensor Networks
- Driving at night is one of the leading causes of traffic related deaths. The lack of adequate light at night impairs a driver, preventing him/her from being able to judge distances between objects accurately as well as preventing a driver from recognizing various objects on the street and avoiding them. Additionally, high intensity light from the headlights of oncoming vehicles causes temporary blindness, leading to accidents. In our proposed research, we measure the intensity of light incident on a vehicle (say V1) from an oncoming vehicle (say V2). If the light intensity is above a certain threshold – calibrated a priori – then vehicle V1 automatically requests the oncoming vehicle V2 to reduce its light intensity. The reduction in light intensity is automatically done by the oncoming vehicle V2 by lowering its light beam fractionally so as to satisfy the first vehicle's (V1's) request, while still maintaining adequate light for the driver of oncoming vehicle (V2). This process may need to be repeated several times before two vehicles cross each other. Thus an optimal headlight attenuation is achieved which satisfies both parties, thereby improving visibility and traffic safety.Presenter bio: Vishnu Narayanan received his Bachelor of Technology degree in Electronics and Communication Engineering from Amrita Vishwa Vidyapeetham, Kollam, India in 2014.

- 10:20 Southeast Michigan 2014 Test Bed Project Architecture Update: Developing, Refining and Implementing the USDOT's Connected Vehicle Reference Implementation Architecture
- The US Department of Transportation's (USDOT) Southeast Michigan Connected Vehicle Test Bed originally hosted the USDOT Proof of Concept Testing (POC), starting in 2007. The USDOT, following the success of the POC, initiated the development of a Connected Vehicle Reference Implementation Architecture (CVRIA), and in 2013 began the final design of trial implementation of the CVRIA at the USDOT's Southeast Michigan Connected Vehicle Test Bed. All users of this facility will be encouraged to develop and deploy solutions (hardware and software) using a common graphical language that is based on the updated ITS National Architecture. The development of the project architecture for the Southeast Michigan 2014 Test Bed project has been an iterative process as it is the first real-world implementation of the CVRIA. As a result, the initial architecture design shown in December 2013 has evolved significantly based both on lessons learned from the development and showcasing of the architecture and from the implementation of various components that resulted in changes to the architecture to facilitate implementation and long-term growth and use of the system. The Southeast Michigan Test Bed must be built to accommodate a wide range of user agreements. It must be secure and accessible to a wide range of users, including the traveler - often multi-modal - and commercial and transportation providers and authorities. In addition, in must be flexible enough to support additional test beds throughout the country by providing a common platform that permits those facilities to focus their resources on testing and developing applications and systems that are relevant to those test beds. In this paper we present the updated system architecture and our process for evaluation through industry collaboration.
- 10:40 Front-End Buck-Rectifiers with Regeneration Capabilities
- This paper presents a high-frequency (HF) transformer solution for front-end rectification, which will especially find its suitability for traction applications. The topology is based on PWM buck-rectifier (CSI topology) and is capable of rectification and attenuation of ac voltage in a single stage. Considering the demand of high quality source current and upf operation, a single-loop control scheme is proposed which maintains constant load voltage both under powering and regenerative modes. Based on the analytical derivations, simulation results for load transition from powering to regenerative mode are included.
- 11:00 Edge level Vehicular Traffic Estimation using Cellular Infrastructure and Other sources
- Intelligent Transportation Systems (ITS) play major role in generating fine grained vehicular traffic information for city wide or larger region. However, in developing countries like India, limited ITS infrastructure is available. On the other hand, cellular infrastructure is widely deployed in India with more than 867 million cellular connections and more than 70% cellular teledensity. Also, on some major arterial roads, video cameras are deployed for surveillance purpose. Aim of this study is to assess feasibility of using these alternate sources to generate accurate traffic information for all the edges in road network. The simulation results show that, even with large location error of 250-500 meters, edge level vehicle flow estimation with good accuracy (less than 10% error) is feasible using cellular network data. Using cellular network data alone, the edges can be classified as congested or uncongested. For edge level speed estimation, we propose a simple and novel approach for fusing widely available but erroneous flow data from cellular network with the spatially sparse but accurate flow-speed data from other sources (e.g. loop detector or video cameras). The simulation results show that edge level speed estimation with good accuracy (less than 15% median error) is feasible using the proposed approach.
- 11:20 Development of risk factor management method for federation of clouds

The approach is based on risk assessment technology and implements cloud federations without consideration of identity federations. Here, for solving this problem, first of all, important factors which are capable of seriously influencing the information security level of clouds are selected and then hierarchical risk assessment architecture is proposed based on these factors. Then, cloud provider's risk priority vectors are formed by applying the AHP methodology and fuzzy logic excerpt type risk evaluation is carried out based on this vector.Presenter bio: Fargana Abdullayeva is a senior scientist researcher in Institute of Information Technology of Azerbaijan National Academy of Sciences.

- 11:40 Vehicle Road Distance Measurement and Maintenance in RFID Systems on Roads
- In order to enhance the safety of driving, we propose a vehicle road distance measurement and maintenance system (RDMMS) based on the emerging RFID systems on Roads (RSR), where RFID tags are deployed on the road surface to provide road information to the vehicle that has installed an RFID reader. RDMMS can measure the road distance between two vehicles via analyzing the information stored in the RFID tags and adjust the vehicle speed according to the safe distance requirement and the estimated status of the vehicle in front. Simulations demonstrate that RDMMS can always successfully avoid rear-end collision under several driving environments while keeping the driver comfortable.Presenter bio: Wei Cheng is an Assistant Professor of Computer Science in Virginia Commonwealth University.

- 10:20 Modern Vibration Signal Processing Techniques for Vehicle Gearbox Fault Diagnosis
- This paper presents modern vibration signal-processing techniques for vehicle gearbox fault diagnosis, via the wavelet analysis (WT) and the envelope technique. The results show that all approaches are effective for detecting and diagnosing localised gear faults under different operation conditions, and are more sensitive and robust than current gear diagnostic techniques. Where, the wavelet analysis is regarded as a powerful tool for the detection of sudden changes in non-stationary signals. The envelope technique has been extensively used for rolling bearing diagnostics. In the present work a scheme of using the envelope technique for early detection of gear tooth pits. The pitting defect is manufactured on the tooth side of gear of the fifth speed on the intermediate shaft of vehicle gearbox. The objective is to supplement the current techniques of gearbox fault diagnosis based on using the raw vibration and ordered signals. The test stand is equipped with three dynamometers; the input dynamometer serves as internal combustion engine, the output dynamometers introduce the load on the flanges of output joint shafts.
- 10:40 Hybrid Decision and Data Adaptive Antenna Array Processing for Collision Avoidance Radar
- In this paper we describe a hybrid data and decision adaptive beam forming and processing strategy using a novel W band phased array architecture for automotive collision avoidance radars. We use the term 'decision adaptive' to denote the situation where the output of a tracking algorithm initializes the weight vector of the antenna array such that the main formed beam can be coarsely steered toward a desired, conjectured target location and clutter can be nulled. We use 'data adaptive' in the classic sense where the structure of the data provides fine angular resolution target angle estimates. This is also known as digital beamforming (DBF). This type of approach has three advantages for an automotive radar system: 1) the coarse direction beam weights are stored a priori and a simple look up table is used which makes real time computation trivial; 2) the DBF algorithm is applied at a lower dimension which alleviates both training and computation burdens; and 3) a simplified antenna array system can be used in which the various antenna channels are weighted and pre-combined into subarrays prior to the receiver electronics. This reduces on-chip real estate burden in manufacturing. We will show via analysis and simulation the performance of such a system.Presenter bio: Dr. Subotic is a co-director of the Michigan Tech Research Institute.

- 11:00 Measurement and Modeling of Low-Frequency Electromagnetic Noise Generated by Moving Trains in 25 kV AC High-Speed Railway Lines
- This paper deals with measurement and modeling of conducted and radiated emissions (CE and RE) of high-speed trains in the low-frequency range 9-150 kHz, which are mainly generated by power-electronic converters. Firstly, an experimental procedure and a post-processing method, based on the median filter, is proposed to improve procedures foreseen in current Standard IEC 62236-2. Specifically, magnetic-field RE are characterized by a time-frequency representation, and stationary emissions are separated from transient events. Finally, a simplified model for the prediction of CE and RE is presented and compared versus a previously developed multiconductor-transmission-line approach. It is shown that the proposed simplified model provides useful results, as long as the spatial distribution of the radiated field (and not the estimation of emission levels) is of interest.Presenter bio: GIORDANO SPADACINI is an Assistant Professor of Electrical Engineering with Politecnico di Milano, Milan, Italy.

- 11:20 On the use of bulk current injection for testing the immunity of CAN-Bus lines
- In this work, an immunity test based on the Bulk Current Injection (BCI) test procedure is simulated, with the objective to predict the radio-frequency (RF) noise currents injected into the terminations of a CAN-bus line. To this end, an accurate model of the injection probe is combined with typical injection profiles recommended by automotive Electromagnetic Compatibility (EMC) Standards, and with a distributed-parameter representation of the wiring harness. The model also includes possible imbalance affecting the bus terminal sections, whose non-ideal behavior is recognized to be at the basis of bus susceptibility to electromagnetic interference. As a matter of fact, the obtained predictions prove the great sensitivity of the injected current to the degree of imbalance of the terminal sections, and indicate that, in order to derive from the test consistent information to fix possible susceptibility problems, statistical models accounting for the uncertainty associated with the involved circuit components are preferable, unless accurate characterization of the terminal sections were available.Presenter bio: GIORDANO SPADACINI is an Assistant Professor of Electrical Engineering with Politecnico di Milano, Milan, Italy.

- 11:40 Modeling conducted noise propagation along high-voltage dc power buses for electric vehicle applications
- A multiconductor-transmission-line (MTL) model of the high-voltage dc power bus of electric vehicles (composed of two shielded cables running above a metallic ground) is proposed for the prediction of the propagation of conducted electromagnetic noise up to 100 MHz. Model parameters are computed by knowing the geometry of the system and the permittivity of dielectric materials. The proposed model is validated versus measurements. Finally, an approximate lumped-parameter circuit representation is also derived from the general MTL formulation, which is specifically useful for the implementation of the model in a SPICE circuit solver.Presenter bio: GIORDANO SPADACINI is an Assistant Professor of Electrical Engineering with Politecnico di Milano, Milan, Italy.

- 12:00 Ethernet Video Analyzer for Vehicles
- The great raise in the number of Electronic Control Units (ECUs) transmitting video flows (cameras) and networking vehicular technologies has caused a raised amount of exchanged video data on in-car network. Besides, the real-time audio and video based driver assistance systems have increased swiftly. These developments have imposed new requisites in terms of data rates, efficiency, performance, capacity, etc. To date, the interconnection of in-car stream oriented tools has been accomplished by several automotive networks with restricted transmission capacities. Since IP over Ethernet affords fine conditions for video streaming by recommending high transmission capacities, modern BMW cars exploit Ethernet BroadR-Reach for connecting automotive cameras. In this paper, we will present the Ethernet video analyzer tool that record, store, decode and display the video flow for further tasks such as statistics and camera performance evaluation.Presenter bio: Hela Lajmi was born in Sfax, Tunisia, in 1985.

- 10:20 Monte Carlo Modelling for Domestic Car Use Patterns in United Kingdom
- For the purposes of quantifying the potential impact of widespread electric vehicles (EV) charging on the UK's power distribution system, it is essential to obtain relevant statistical data on domestic vehicle usage. Since electric vehicle ownership is presently very limited, these data will inevitably be for conventional internal combustion engine (ICE) vehicles, and in particular privately owned vehicles. This should not be an issue since the limited journey distances that will dealt with in this work could as easily be undertaken by an electric vehicle as a conventional vehicle. Particular attention is paid to the United Kingdom 2000 Time Use Survey (TUS) as contains detailed and valuable statistical information about household car use. This database has been analysis to obtain detailed car use statistics, such as departure and arrival time, individual journey time, etc. This statistical information is then used to build up two Monte Carlo (MC) simulation models in order to reproduce weekday car driving patterns based on these probability distributions The Monte Carlo methodology is a well-known technique for solving uncertainty problems. In this paper, key statistics of domestic car use is shown in details and two different Monte Carlo simulation approaches are presented and the simulation results have been analyzed to verify the results are as expected and are consistent with the statistics extracted from the TUS data.Presenter bio: Sikai Huang is a research assistant in the Department of Electronic and Electrical Engineering at the University of Strathclyde, where he completed his BEng Honor degree of Electronic and Electrical Engineering in 2008.

- 10:40 Assessment of Electric Vehicle Charging Load and its Impact on Electricity Market Price
- State of the art electric drive vehicles are one of the most encouraging automobile technologies to reduce our dependence on expensive, polluting fossil fuel based conventional vehicles. However, arises a new fear: the grid anxiety - whether the existing power grid, as it stands right now, will be able to handle the additional load put up by these vehicles. In this work, actual transportation statistics, together with two possible charging schemes - constant time and constant power for two charging levels of 3.3 and 6.6 kW, have been used to obtain the load profile of electric vehicles. The augmented charging load of electric vehicles may also affect the behavior of electricity market due to increase in total load. This paper analyzes the impact of vehicle's load on electricity market price in a day ahead market model. The constant time charging along with low charging power comes out to be an optimal scenario, when tested on a modified IEEE 30-Bus system.Presenter bio: Prateek Jain was born in Sagar, India.

- 11:40 Modeling Spare Capacity Reuse in EV Charging Stations based on the Li-ion Battery Profile
- Li-ion batteries, widely used in electric vehicles (EVs), have a specific charging profile where the power consumed varies over time and defines the amount of power the charging station needs to deliver. Achieving a proper tradeoff between charging levels, number of vehicles, and electric capacity of the plant is challenging. In order to give a solid basis for the deployment of efficient charging systems, we propose a bi-dimensional Markov chain model that considers the practical characteristics of Li-ion charging profiles. To this end, we build two scenarios that differ in their capacity to handle idle slots. We show through extensive numerical analysis that the use of spare sockets in different sizes of charging stations contributes to better energy utilization. Moreover, we apply the proposed model to the case of the city of Rio de Janeiro and show that, in a foreseeable future, if all ICE (Internal Combustion Engine) vehicles were replaced by EVs, the adoption of charging station with spare sockets will produce significantly better results in terms of availability of the station, number of admitted vehicles, and energy utilization.
- 12:00 First approach of profiling users of Electric Vehicles in Colombia
- Due to climate change and reduction of fossil fuel reserves, such as oil, the introduction of electric vehicles (EVs) to market is presented as an increasingly necessary option. Not only it promotes a more efficient vehicle fleet, but results in a friendly solution with the environment. The mass adoption of EVs can be guaranteed if the potential user is identified; it implies the analysis of the requirements and constraints for the user who wants to acquire an EV. This will define the trend of the EVs technology that suits better the driver's mobility patterns. This paper evaluates the user's perception of EVs in Bogota and identifies the profile of the potential users, their needs, requirements and constraints when purchasing an EV.

- 10:40 Secure Pairwise Key Establishment in Vehicular Networks
- In vehicular networks, automobiles assist each other in accident avoidance and information sharing. However, securing the On Board Unit (OBU)'s stored and communicated data is not an easy task. In this paper, we suggest a tactic, which combines an elegant key pre-distribution scheme  with a somewhat homomorphic encrypting system (Boneh-Goh-Nissim)  to provide muddled secure session keys that can be used for encrypting transferred data in case of sudden disappearance of the vehicle to infrastructure (V2I) service. To investigate the appropriateness of the suggested model, in-depth analysis in terms of OBU storage and time overhead has been conducted and the analytical results show that our scenario is practical and fast only when some idealistic assumptions are made for small network sizes and compromisation rates.Presenter bio: Sarah Al-Shareeda is a recent PhD graduate from the Department of Electrical and Computer Engineering, The Ohio State University and a Fulbright Science and Technology Award's fellow.

- 11:00 A Demand-Aware Location Privacy Protection Scheme in Continuous Location-based Services
- Location-based Services (LBSs) via mobile handled devices have been subject to major privacy concerns for users. Currently, most of the existing works concerning the continuous LBS queries mainly focus on users' privacy demands with little consideration of the service of quality (QoS). In this paper, we propose a Demand-Aware Location Protection scheme DALP for continuous LBS requests, allowing a user to customize not only location privacy but also QoS requirement. While, this results that in considerable query points the privacy and QoS requirement cannot be met together and the location privacy protection cannot be provided for the continuous LBS query. We point out its underlying reason is that in few LBS query regions the footprints are sparse or the privacy requirements are set unreasonably high. Therefore, a maximum Demands-Aware Query Sequence algorithm MaxDAQS is proposed in the scheme. Through identifying and restraining the queries in those regions, most of LBS queries are satisfied, thus, the longest LBS query sequence is obtained which can satisfy a user's specific privacy and QoS requirements simultaneously. The extensive simulations on a large dataset prove the effectiveness of our approach under various location privacy and QoS demands.Presenter bio: Xinghua Li received the ME and PhD degrees in computer science from Xidian University, in 2004 and 2007, respectively.

- 11:20 Evaluation Criterias for Trust Management in Vehicular Ad-hoc Networks (VANETs)
- Vehicular Ad-hoc networks (VANETs) have been around for some time and are still attracting research. VANETs are one of the ad hoc networks real-life applications, where vehicles communicate which each other and with fixed components known as roadside units. VANETs have unique characteristics and requirements which differ from those in standard ad-hoc networks, but the security remains a major challenge because of the very dynamic topology and the lack of infrastructure. In this autonomous and auto-organized environment, the question of whom to trust and for what becomes very important and difficult to answer. This paper addresses the issues associated with establishing trust between peers in VANET. It defines, discusses and evaluates various trust management approaches and how well they address VANET requirements. The paper also proposes criteria for assessing the effectiveness of trust management models with regards to challenges specific to VANETsPresenter bio: Asma Adnane obtained her PhD degree in 2008 at the University of Rennes in France.

- 11:40 A Secure QoS Proposal for Vehicular Networks
- Currently, VANETs (Vehicular Ad-hoc Networks) are attracting a lot of interest by the scientific community because of their usefulness in the deployment of more Intelligent Transportation Systems. However, due to the high mobility of vehicles the handover process in this sort of networks represents a serious problem, particularly when vehicles are running real-time applications such as VoIP. The goal of this work is to enhance the handover management in vehicular networks. To accomplish this goal we propose a solution, which underlies on a pre-registration phase, which will be used to exchange security and QoS (Quality of Service) parameters before the occurrence of the one handover. The proposed solution allows having secure handovers and supports Quality of Service (QoS) for applications with different requirements in VANETs. The obtained results demonstrate that the proposed solution can substantially reduce the number of handovers, improving this way the quality of the service in a VoIP application.Presenter bio: Nuno Vasco Lopes graduated in Electrical Engineering by UTAD Portugal, in 1998, and obtained a MSc Degree in Telematics at the University of Vigo, Spain, in 2003 and a Phd Degree in Computer Science at the University of Minho in 2011, and made a Post-Doc at the University of Coimbra in 2013.

- We introduce a new view of parked cars as a massive, flexible resource that is currently wasted. Given the power supply in batteries as well as computing, communication, and sensing facilities in cars in conjunction with the precise localization they can provide, parked cars have the potential to serve as a service delivery platform with a wide range of possibilities. We describe diverse applications that can be implemented using parked cars to show the flexibility of the infrastructure. Potential user groups and service providers are discussed. As an illustrative example, a simulation study of the use case of localizing persons in need of assistance is presented. Finally, the need for new algorithms and their analysis adapted to the specifics of parked cars is also highlighted.
- 11:00 Service-Based IoT Architecture For VANETs
- The Internet of Things (IoT) which provides integration of various objects over the Internet, has been widespreadly accepted as a new key technology for the Future Internet. The ability of creating intelligent IoT ecosystems by communicating devices with different networking standards has challenged researchers to apply IoT in different domains such as e-health, military, cities management, logistics, and Intelligent Transportation Systems (ITS). Internet of Things based ITS implementations, specifically for Vehicular Ad Hoc Network (VANETs), essentially focus on seamlessly and transparently incorporating a numerous in-vehicle and out-of-vehicle smart devices which run on heterogeneous protocols, supporting car-to-car communication with allowing data dissemination between them, and providing effective management and optimization on services and underlying algorithms within the vehicular network. As future VANET technology direction is integration of adequate information transfer, reliable and comfortable transportation and energy oriented services, VANETs are considered within the IoT scope. However, taking over control during the communication and computation process is not an easy task. This paper, proposes a service-based IoT architecture in particular for VANETs to precisely ensure both the transparency of the IoT and impact of the Internet as part of the vehicular network architecture. The main conclusion of the research confirms the introduced structure is suitable and successfully applicable for practical scenarios.
- 11:20 ParkinGain: Toward a Smart Parking Application with Value-Added Services Integration
- Drivers cruising for parking are an important cause of traffic congestion in cities. Smart parking applications that make easier the parking search task can help to reduce this traffic and its associated environmental burden. This paper presents the conceptual modeling phase of ParkinGain, a smart parking application that helps drivers to find and reserve parking spots based on their current needs, using their car HMI system or their smartphone. In addition, the application allows the driver to extend the parking time if needed. Since the cost of deploying smart parking technologies is not negligible, the integration of other value-added services such as digital coupons of nearby merchants can help to subsidize the associated costs related to the adoption of these technologies in parking facilities. Our application is designed to integrate these services, allowing to create a smart parking ecosystem that can also be beneficial to other 'non-parking' related parties such as the aforementioned merchants.Presenter bio: Dr. Joachim G.

- 13:30 Beyond mileage - Towards more secure techniques to assess the fitness-levels of smart cars
- Today, mainly the (mile)age is used to assess the value and/or condition of a car. This is a bad/unreliable concept, because the mileage alone is no representative indicator for a car's condition (which truly depends on much more factors) and constitutes a focus point of (frequently successful) attacks. In this paper we propose a new approach of determining a more reliable "fitness level" that extends these basic criteria and illustrate advantages such a fitness level estimation would yield for different use cases and also with regard to security issues like attack resistance. The vision of this concept is to realize this using multimodal, complementary sensor information already present in modern cars. To open the discussion with the community, we discuss the potential of a first set of 18 proposed properties, ranging from 9 physical via 4 digital to 5 behavior-based ones which are open for further future extensions and improvements. As a further contribution this paper proposes a first concept to weight the identified properties by discussing the impact of differences among them in terms of their explanatory power, freshness, security and available options to verify their plausibility. To a basic extend, this concept could even be applied to existing cars which is finally illustrated based on practical analyses using a laboratory setup of a 2008 SUV vehicle and a real 2006 limousine car.Presenter bio: PHD Candidate at the OVGU Magdeburg, Advanced Multimedia and Security Lab under Prof. Dr. Jana Dittmann, graduated computer scientist.

- 13:50 Network-Based Safety-Related Vibration and Position Analysis for Railway Vehicles
- Nowadays many considerable efforts are being focused on the development of efficient and effective systems that increase the productivity of vehicles by controlling and manipulating the extraordinary states during the operational time. Extraordinary states ,such as sliding and spinning, play a central role in the performance of the vehicles described as interaction among different mechanical parts regarding their life-time, their wear and tear, as well as the maintenance costs. In addition, these states ultimately affect the safety of target system and their environment. Therefore, the necessity of avoiding, controlling, or manipulating these states to lower their effects into a tolerable level has become the major driver for conducting the current research work. In this paper, a prototype for safety-related platform for detecting and controlling railway vehicles, states by means of vibration capture is presented. Additionally, test procedures in order to collect the vibration data related to each state are presented; these tests were performed under the supervision of an industrial partner. Moreover, the recognized initial patterns of the vibration signals related to the studied states are also introduced.Presenter bio: Research Assistant in the Institute of Computer Architecture and System Programming at University of Kassel.

- Optimization of circuit breakers (CBs) maintenance schedule based on RCM can enhance substation reliability and lower maintenance cost. In this paper, a RCM approach based on Least Squares Support Vector Machines (LS-SVM) is proposed. Historical operation data are utilized to build a defects tree. A bi-level optimization algorithm is used to choose LS-SVM parameters. The LS-SVM algorithm is used to predict the distribution of defects before and after scheme optimization using aggregated defect data, outage duration, maintenance operation defect detection rate, etc. After the defect loss is quantified based on an expert scoring method and the Gross Domestic Product to power consumption ratio, a cost effect measurement is used to determine the best scheme. The effect of the proposed approach is verified using a numerical simulation of an electric power corporationPresenter bio: Kai Yuan received Bachelor from Wuhan University (WHU) in electrical engineering and automation.

- 14:30 Role of Consumer Electronics platform in vehicular Architecture
- As more features have been added to vehicles, the electrical architecture of the vehicle has transformed a lot. The growth has resulted in a greater degree of complexity in electrical network designs, more ECU's in the vehicle and an increase in the wiring required in supporting these ECUs. The aim of this paper was to analyse technical feasibility and challenges in introducing CE device in to vehicular Architecture and to create an interface between the vehicle and a Consumer Electronics (CE) Device, such that the logic processing for the feature (or as much as possible) was contained within the CE Device and for the feature itself to be controlled by the user via the CE Device. In off-boarding the logic progressing from the vehicle to the CE Device, the intention was to understand whether it is possible to reduce the processing, which each ECU is supposed to do, thereby ideally reducing the ECU count, and hence weight, complexity and power consumption of the vehicle's electrical system. Preferably the vehicle would be left with an IO gateway ECU with minimal logic to interface between sensor actuators and remote CE device where in vehicle features shall be hosted. How this interface is achieved was part of the scope of this technical paper. The proposed paper shall explain the below points on the basis of experimental results, • Understand how a CE device can be used to carry out logic and processing algorithms from an existing ECU. • Understand any issues for the real time control of motor, sensors, actuator etc. from a CE device connected over a Wi-Fi link • Identify any underlying issues with development of vehicle feature on the CE Device platform • Provide feedback into re-defining vehicular architecture with support of CE device platform
- 14:50 Commutation Strategies of Double Sided Linear DC Motor
- Requirement of linear motion in automation systems is an indispensable reality. Linear motion is commonly obtained from rotary motion via gear or belt mechanisms with additional equipment since linear motors have been less preferred than its rotary counter parts because of their problems to be solved. The most significant difficulties with DC linear motors are short stroke, low static thrust-current ratio and necessity of complex power electronic circuit for driving. In this study, commutation strategies of novel double sided PM DC linear motor which was developed has been investigated. The PM DC linear motor devised has no stroke limitations as its stroke could be extended in modular approach. It has a high static thrust-current ratio and does not require any power electronic circuit to drive although it has flexibility to be commutated with electronic circuits. Experimental results of the prototype with different commutation strategies have been presented.
- 15:10 Enabling rapid first-aid alert via smartphones' inertial sensors: the case of two-wheeled vehicles
- Road accidents involving two-wheeled vehicles are numerous indeed, and quite often cause the riders severe injuries. Therefore, developing automatic features that are able to detect the fall of the vehicle and autonomously issue first-aid calls is of particular interest for this type of vehicles. Such systems constitute a very interesting additional feature to be installed on new vehicles, even though vehicle-based solutions could hardly be cost-effective, as they would require additional sensors. To solve the problem in a low-cost and portable way, this paper proposes to use the GPS and the acceleration sensors that are on board of any modern smartphone. By properly processing these signals it is possible to detect whether the vehicle and/or the rider is lying on the ground and to issue an emergency call. The results are based on the analysis of experimental data measured on both an electric and a traditional two wheeled vehicle.

- 13:30 Thermal management consumption and its effect on remaining range estimation of electric vehicles
- This paper investigates the significance of thermal management energy consumption on the range of electric vehicles. It is necessary to combine consumption models of powertrain components such as the electric machine, power electronics and high voltage battery that take into account trip-based information containing a predicted speed profile and elevation data with a thermal management system that has the ability to incorporate predicted thermal losses of the powertrain. The thermal management system refers to the sum of all components within the refrigeration cycle of the vehicle as well as the associated control strategy. Based on the results of a real world drive study in an electric vehicle, it is demonstrated, that the range uncertainties introduced by the consumption of the thermal management are significant and should be considered when developing predictive range estimation algorithms. These uncertainties are further investigated by an energy flow based thermal system model. In order to minimize range uncertainties, a system architecture for the prediction of thermal management consumption is proposed.Presenter bio: Achim Enthaler is a predevelopment engineer at AUDI AG, Germany and a doctoral candidate at the Institute of Vehicle System Technology at Karlsruhe Institute of Technology.

EVs with excess of energy in their batteries can transfer this energy among other EVs which need charge during their daily trips.

- 14:50 Driving Without Anxiety: a Route Planner Service with Range Prediction for the Electric Vehicles
- In modern smart cities, mobility based on Electric Vehicles (EVs) is considered a key factor to reduce carbon emissions and pollution. However, despite the global interest and the investments worldwide, the user acceptance level is still low, mainly due to the lack of charging services support. This is one of the main causes for the so called "EV driver's anxiety", and has led people to consider EV mobility suitable only for short routes. To contrast this issue, we propose here a route planner application supporting EV mobility also on medium and long routes, through prediction of range and charging stops. Our application estimates the minimal energy consumption path, by also considering the overhead to reach the charging stations along the way towards the destination. We demonstrate the optimality of the algorithm and we describe its implementation within a Web-application which connects to charging providers' services (to retrieve the locations of charging spots) and to Google services (for routing directions and real-time traffic data). Finally, we evaluate the scalability of our application, and we study its effectiveness in supporting EV routes on large-scale scenarios (e.g. the Emila-Romagna region in Italy) through immersive simulation techniques.Presenter bio: Marco Di Felice received a Master and Ph.D degree in Computer Science in 2004 and 2008, both from the University of Bologna, Italy.

- In automotive and ITS industries, quality of wireless communication technologies become a hot research topic, as wireless technologies have been applied not only to entertainment or information applications, but also to mission critical safety applications. These applications have challenges, such as, large speed of wireless transmitter/receiver in a vehicle, critical radio environment for example building canyons and tunnels. Moreover, in crash warning applications by using peer-to-peer (vehicle-to-vehicle) communications, vehicles have to exchange their locations, speeds and directions between neighboring vehicles, within a few seconds prior to potential vehicle crashes, even in freeway intersections crowded with over 100 vehicles. In this paper, we will first introduce crash warning applications with vehicle-to-vehicle communication and its preliminary field assessment. Then we will introduce our simulation results of vehicle-to-vehicle communication quality for crash warning applications with considering radio interference from neighboring vehicles. Then we will introduce various multi-antenna solutions, including MIMO (Multi Input Multi Output) that improve the vehicle-to-vehicle communication quality to help more vehicles exchange data within shorter time even in areas crowded with many vehicles, including their advantages and challenges for automotive and ITS applications.Presenter bio: Hiro Onishi is specialist at Alpine Electronics Research of America, Inc., and he is researching ITS (Intelligent Transportation System) and Intelligent vehicle technologies, more than 25 years.

- 13:50 Assessment of Design Methodologies for Vehicular 802.11p Antenna Systems
- In this contribution, we propose and analyze performance metrics for vehicular antenna systems. Considered metrics are the following: Delta(D, RSS) giving the difference in received signal strength (RSS) of the antennas, thus illustrating their supported diversity efficiency. The antenna gain outage rate Rho(G) and the probability of antenna gain differences Rho(D). Further, the proposed performance metrics are evaluated for three prototypical vehicular antenna systems to assess their suitability for supporting IEEE 802.11p. The considered vehicular antenna prototypes employ different design methodologies to limit the interaction between their 802.11p and cellular antennas. By comparing the prototype systems based on mismatch, antenna isolation and metrics for the antenna radiation pattern, we assess their performance. We apply our benchmark results to measurements performed in a 802.11p testbed. Each prototype antenna system is evaluated according to the offered diversity efficiency, which we assess according to the RSS measured with both 802.11p antennas.

- 14:30 Bigger is Better - Combining Contention Window Adaptation with Geo-based Backoff Generation in DSRC Networks
- The vision of safer transportation is strongly driven by the introduction of Vehicular Safety Communications (VSC) to enable new cooperative safety applications. In highly dense traffic scenarios, however, the current Dedicated Short Range Communications (DSRC) technology is expected to face serious performance problems due to simultaneous transmissions making packets to collide with each other. In this paper, we first analyze the sources of packet collisions. The analysis reveals a significant amount of simultaneous transmissions as vehicles have chosen the same backoff counter, especially in the close vicinity, which is the most critical area with respect to safety. Based on these observations, we then introduce a new concept for DSRC backoff generation called geo-backoff. It implements two countermeasures: First, we increase the Contention Window (CW) to reduce the probability of simultaneous transmissions in general. Second, we exploit geographical information for generating the current backoff counter to further reduce the probability of packet collisions at short (critical) ranges. We analyze our concept from a traditional TX-RX perspective (latency) as well as an RX-centric perspective (update delay). The simulation results indeed have shown that geo-backoff is able to improve the communication performance, but the improvement is mainly dominated by just increasing the CW.
- 14:50 Virtual Road Side Units for Geo-Routing in VANETs
- Vehicular networking is the new key context to offload the cellular network of the great amount of contents produced on the move. In this paper, we focus on the exploitation of vehicle-to-vehicle communications to deliver part of the data produced on board to the road side units (RSUs) deployed in the scenario, avoiding, as much as possible, the adoption of the cellular network. Specifically, we propose a novel routing algorithm that is based on the greedy forwarding approach and uses virtual RSUs to overcome the problem of the local minima. Through the exploitation of the proposed algorithm, data can be redirected through optimized directions with limited amount of added information. In addition, system optimization can be performed via software and the choice of the RSU positions becomes less critical. The effectiveness of the proposed algorithm is demonstrated through simulations performed using realistic vehicular traces in two European cities, showing that the proposed solution increases the amount of data transmitted through the vehicular networks.Presenter bio: Alessandro Bazzi is a research associate of the National Research Council of Italy and he acts as Adjunct Professor at the University of Bologna for courses in the field of wireless communications.

- 13:30 Adaptive Cooperative Maneuver Planning Algorithm for Conflict Resolution in Diverse Traffic Situations
- Growing interest in Cooperative Driving within the field of Intelligent Transport Systems (ITS) put forth novel concepts for both enhanced sensing and advanced solution making. Although various approaches deal with advanced solution making, none of the concepts consider the conflict situation as an integrated conflict comprising defined end states and trajectories towards them. We propose a novel algorithm for cooperative maneuver planning that is not meant to optimize a high level strategy but shall solve a conflict in the following five steps: target point generation, risk assessment, trajectory generation, combination including assessment, and execution of the maneuvers. The proposed cooperative maneuver planning algorithm is applicable to all kinds of road users' interferences (safety, comfort, time efficiency, and consumption efficiency), highly adaptive in terms of complexity and scalability, individually parameterizable, and applicable in diverse and mixed traffic situations. Simulations indicate the wide usability and performance of this approach in two different scenarios.

- 13:50 Analysis and Design of ElectromagneticVehicles Climbing on Steel Plates
- For facilitating inspection and maintenance, robots that can wander on walls made of steel are much in demand, Especially in situation like ship hulls and surfaces of large oil tank. So a strategy for such vehicles that carry such robots is presented in this paper based on the theory of electromagnetism. Differing from the former strategies, the proposed one makes use of the steel plate as partial magnetic circuit, which can provide thrust and attractive force simultaneously, so that the vehicle structure is simplified. A prototype was designed and manufactured. Simulating and experimental results show that the proposed strategy is valid.
- 14:10 Gamified Training for Vehicular User Interfaces - Effects on Drivers' Behavior
- In densely populated areas, we currently see a paradigm shift in personal mobility. For the younger generation, car usership is gradually replacing the need of car ownership. However, for example, when relying on car sharing solutions, users often spontaneously drive cars they are not used to. Results are increased stress and a higher risk of accidents. For that reason, we present a mobile application-based training solution for vehicular user interfaces. The evaluation of the training application has shown that a short training cannot counteract the negative influence of operating comfort car functions while driving. The use of game design elements in the application increased the training motivation, but also lowered the information reception.Presenter bio: Stefan Diewald studied Electrical Engineering and Information Technology, majoring in Communication and Information Technology, at the Technische Universität München (Germany).

- 14:30 Predictive longitudinal vehicle control based on vehicle-to-infrastructure communication
- Governments, industries and last but not least customer's demand for low-pollutant, efficient and comfortable vehicles has extended the system development scope towards the combination of in-vehicle systems and environment. Whereas the information from the on-board systems is available for several functions per se the environmental information has to be grabbed using sensors and/or communication devices. Optimizing fuel efficiency whilst offering a high driving comfort is the goal of the predictive cruise control functionality. An assistance function for intersections is presented within this paper. Traffic signal data is used to automatically adjust the optimal vehicle velocity during urban drive cycles through passages with intersections. The target is to avoid unnecessary acceleration and braking maneuvers which results in reduced fuel consumption. In combination with the adaptive cruise control function a full takeover of the longitudinal vehicle control is realized. Communication between vehicle and traffic lights is done using a wireless vehicle-to-infrastructure communication technique. The presented work describes the developed algorithm 'Predictive Cruise Control - Intersection Assist' such as the coupled simulation environment for the examination of the function performance. The later one involves vehicle, driver, traffic lights and wireless transmission. The effect of varying communication ranges is considered using a probability distribution function. Within the study several scenarios with and without traffic were analysed and evaluated. As a result the fuel efficiency of the implemented assistance function is confirmed. Furthermore a trip time reduction could be achieved in most of the scenarios.Presenter bio: Dr. Michael Karner is Lead Researcher at Virtual Vehicle Research Center, Austria.

- 14:50 Dynamic Curvature Path Tracking Control for Autonomous Vehicle: Experimental Results
- This paper discusses a new path tracking controller strategy for autonomous vehicle. Preliminary works done by researchers shows that most of the controller performs well in a straight path and normal curve. However, the problem arises in tight curve or discontinuous path. Therefore, this work aims to reduce the gap on the tight corner problem. The controller is designed based on the dynamic curvature estimation to predict the path condition and modify the wheel speed and steering wheel angle accordingly. In this technique, the curvature estimation algorithm is presented as a required input to the controller. The curvature estimation allows the vehicle to react based on the curvature profile and threshold region detection. The comparison is made based on three different path types. The experimental results on the autonomous prototype platform are discussed to show the effectiveness of the controller.

- 16:10 Benefits of Inerters for Multi-Car Trains
- This paper applies the inerter to multi-car trains, and discusses its benefits in improving system stability and performance. An inerter is a genuine two-terminal passive mechanical element, whose reacting force is proportional to the relative acceleration of its terminals. In this paper, we build the model of multi-car trains, and discuss the advantages of applying inerters in the suspensions. The study is carried out by three steps. First, we construct a thirty-one degree-of-freedom full-train model. Second, we show that inerters can significantly improve the system's stability and performance. Last, we link multi cars, and discuss the impacts of connecting cars on system stability and performance. Based on the results, the inerters are deemed effective in improving the performance and stability of multi-car trains. Furthermore, connecting cars tends to decrease the critical speed and increase the settling time, but has no influence on the passenger comfort.Presenter bio: Fu-Cheng Wang was born in Taipei, Taiwan, in 1968.

- The design of more sustainable transportation systems is an achievement that modern societies are aiming to reach. In effect, the realization of transportation supply systems and services that can help reducing the number of private vehicles is a challenge that have attracted the attention not only of researchers, but also of administrations. In this framework, particular attention is devoted to the design and the management of cheap and flexible transportation modes that can significantly boost the modal shift towards more sustainable modes. The model proposed in this paper represents an improvement of the Generalize Ride Sharing (GRS) system introduced in ICCVE2013 by means of the statement of a new optimization problem for determining the optimal departure and arrival times of users in addition to the optimal user/mode matches. Additional aims of this work are the completion of the dynamic models of the considered transportation modes and the discussion of new simulation results.Presenter bio: Edoardo Cangialosi, Ph.D. student at Dept. of Mechanical,Energy, Management and Transportation Engineering - Polytechnic School, University of Genoa.

In particular, the main purposes of his studies are the definition, design and optimization of a Generalized Ride Sharing (GRS) system where not only the traditional car-owners propose trips to the so-called riders, but also buses, taxies and even car-sharing vehicles can be thought of as drivers.
- 16:50 Mental Workload of Young Drivers during Curve Negotiation
- An experiment was conducted in a fixed-base driving simulator to observe young drivers' performance and their physiology changes under high mental workload, while responding to two sets of mental tasks: n-back and sound counting. 20 drivers (9 of them younger than 25 (range 21-24) and 11 older than 25 (range 29-33) were instructed to drive along two sections on a highway at a constant speed. NASA-TLX scores for workload suggest an overall higher level of workload for the young drivers. For all participants, there were significant changes in heart rate when driving under high workload, compared to the single task of driving. Especially, it is significantly higher during curve negotiation. This effect was again more significant for young driver.

- 16:10 Assessing the Effect of Introducing Adaptive Charging Stations in Public EV Charging Infrastructures
- The availability of publicly accessible charging stations in urban areas can foster the widespread adoption of Electric Vehicles (EVs). However, the introduction of public charging infrastructures will put an additional strain on the power grid due to the possible occurrence of peak demands. This study is a first attempt to quantitatively assess the potential benefits of introducing in a public charging infrastructure smart charging stations that are capable of modulating the current supplied to the EVs. Specifically, we assume that each charging station has limited power resources that must be shared among the EVs attached to its charging sockets according to a given scheduling strategy. To evaluate the performance of such system we utilise SUMO, an open-source and widely used vehicular traffic simulator, along with a highly realistic mobility trace for the metropolitan area of Luxembourg City. Simulation results indicate that the use of simple charging strategies that take advantage of the modulation capabilities of smart charging stations (e.g., fair-sharing or token-based scheduling approaches) can effectively mitigate the impact of EV charging demands on the power grid with a limited degradation of charging performance. However, our results also confirm that a significant investment on charging infrastructure might be necessary to guarantee a non-blocking charging service.Presenter bio: Raffaele Bruno is a researcher at IIT, an institute of the Italian National Research Council (CNR).

- 16:30 A framework for electric vehicle charging strategy optimization tested for travel demand generated by an activity-based model
- This paper presents the cost optimization model which plans a charging strategy for an electric vehicle. In case of time dependent electric prices an intelligent planner is required which plans the charging strategy only at cheaper moments and places to keep the vehicle charged enough to complete its scheduled travels. This model estimates the required charging energy to travel by the electric vehicle. Then using the time dependent electric prices and available power at each period of the time suggests a charging pattern for the electric vehicle which ensures the cheapest charging cost and fulfills the constraints of battery state of the charge. According to the current market share of electric vehicles, a fraction of daily agendas created by the large scale activity-based model are used to test the proposed framework. A central power tracker is introduced which keeps track of available and required power at each period of the day. It also manages the charging requests from electric vehicles. Moreover, an experiment has been set up, it makes use of wind and solar energy production data. Price signal is derived from available power as an indicator of relative cost.Presenter bio: Muhammad Usman is a PhD student working at Transportation Research Institute, University Hasselt.

- 16:50 Lifetime Simulation of Different Lithium-Ion Batteries for Vehicle-to-Grid Application
- This work presents an electrical equivalent circuit model for plug-in (hybrid) electric vehicles. The model features ageing dependent parameter adoption to facilitate the simulation of ageing influences on batteries. An ageing approach based on Arrhenius' law for the standstill time and a cubic equation for transferred charge was used making the model capable of vehicle simulations with high percentages of idle phases during their long lifetime. In this case, the additional ageing through vehicle to grid use of the battery is investigated. Therefore, the model was parametrized with the data from two off-the-shelf large scale automotive cells and one generic value cell based on warranty data of commercial vehicles for comparison. Five different energy-intensive user scenarios are simulated giving lifetime values for applications with and without three different vehicle to grid modes. The cost resulting through the reduced lifetime is calculated and the first cost for the regulating energy is derived from these values.Presenter bio: Hartmut Popp, (male) holds a BSc and a MSc degree in Industrial Electronics from the University of Applied Sciences Technikum Vienna and a Dipl.-Ing. degree (MSc equivalent) in Environment and Bio-Resources Management from the University of Natural Resources and Life Sciences, Vienna.

- 17:30 A Publish/Subscribe Communication Framework For Managing Electric Vehicle Charging
- Electric Vehicle (EV) based applications have recently received wide interests from both commercial and research communities, thanks to the avoidance of CO2 pollution by using electric energy instead of traditional fuel energy. With the deployment of public Charging Stations (CSs), the travelling distance of EVs could be substantially increased by recharging their electric energy during journeys. Different from the existing research on decision making to improve charging performance, in this paper we focus on how necessary dynamic information in relation to the charging service can be efficiently disseminated to on-the-move EVs which potentially require charging at CSs. We propose an efficient communication framework based on Publish/Subscribe (P/S) mechanism to disseminate necessary information of CSs to EVs. Those EVs subscribing to such information could then make their individual decisions to select a desired CS for charging, according to received information such as expected waiting time. A core part of communication framework is the utilization of Road Side Units (RSUs) to bridge the information flow from CSs to EVs, which has been regarded as a type of cost-efficient communication infrastructure. In this context, we introduce two complementary communication modes, namely Push and Pull Modes, in order to enable the required information dissemination operation. Both options are evaluated based on realistic simulation models, in particular on how information freshness can influence the overall charging performance based on a common CS selection strategy.Presenter bio: Yue Cao received the PhD degree from the Institute for Communication Systems (ICS), at University of Surrey, Guildford, UK in 2013.

- 15:50 Traffic Generator for HSDPA Network Simulations
- In the last few years numerous connected vehicular applications and services have been developed. Most of them reside in the infotainment domain, but safety-critical use cases are within the scope of current realizations. As the performance of the wireless link has a major influence on the applications' reliability and functionality, it is important to consider its characteristics as early as possible during the development process. In the prototyping stage network simulators are powerful tools. Dedicated scenarios can be arranged and repeated as often as needed in a reproducible way. To improve the validity of the simulation results, the wireless link has to be modeled as realistically as possible, considering in particular the data traffic of concurrently active users. By focusing on High Speed Downlink Packet Access (HSDPA) we present a novel traffic generator, which is realized in the NodeB's scheduler. The traffic generator places additional User Equipments (UE) inside the scheduling process, which produce the desired network load. The number of additional UEs is derived from large sets of in-field client-side throughput measurements producing simulation results, which are very close to reality. The new approach is presented spanning from the modeling of traffic to the final implementation and validation using the network simulator ns-2.Presenter bio: - studied electrical engineering from 1991 until 1997 at the Technische Universität Braunschweig - worked as software engineer and software architect in projects focussing on driver information and driver assistance systems. - since 2010: technical director of the company "c4c Engineering GmbH" in Braunschweig, Germany
- 16:10 Doppler Domain Localization for Collision Avoidance in VANETs by Using Omnidirectional Antennas
- Vehicle-2-Vehicle safety applications using Dedicated Short Range Communication (DSRC) radios allow automobiles to exchange Basic Safety Messages (BSMs) to avoid automotive collisions. Most of these applications rely on GPS and integrated on-board sensors to obtain the position and motion information that is transmitted in a BSM. In the event that the BSM contents are compromised (i.e. hacking), providing an alternative method to detect impending collisions is critical. This paper proposes a creative architecture that uses omni-directional antennas to achieve 3D localization and employs Doppler domain analysis to determine the threat of collision, without changing any existing DSRC protocols. Through rigorous mathematical modeling and simulations, the feasibility of this architecture can correctly predict a head-on collision with an accuracy up to 60.87% and an optimal false alarm rate as low as of 41.70%.Presenter bio: Billy Kihei, Ph.D. is an active researcher in the connected vehicle industry.

- 16:30 Joint Relay Selection and Power Allocation for Pairwise Multi-Way Relay Networks
- We consider a multi-way relay network in which all source nodes share their data by the help of multiple singleantenna relay nodes. To mitigate a loss in the spectral efficiency, the network employs a pairwise digital network coding (DNC) which pairs the source nodes for simultaneous transmission so that the relay forwards the DNC bits of the pairs. For the network, we devise a joint relay selection and power allocation (RS-PA) scheme based on an approximation on the instantaneous symbol error probability incorporating error propagations. Simulation results show that the network with the proposed RS-PA outperforms the conventional network with the RS only with a larger gain with a larger number of relays.Presenter bio: I received the B.S. degree in electrical engineering from the Ho Chi Minh City University of Technology, Ho Chi Minh, Vietnam, in 2010, and the Ph.D. degree from the Department of Electronics and Radio Engineering, Kyung Hee University, Yongin, South Korea, in 2016.

- 16:50 Fault Tolerance Design and Analysis in Automotive Ethernet Topology
- With the advance of automotive development, the requirements of vehicle network like bandwidth, speed and reliability are increasing continually. To find an extendable, reliable and practical vehicle network, people began to survey the automotive Ethernet network. However, distributed intelligent vehicle control system is complex enough. Therefore, we must consider three issues (1.EMI 2.Topology 3. Reliability) when we design. About EMI, we have already known that low-pass filter used at the network transport can successfully reach the vehicle standard of radiative interference, and the Ethernet immunity can be proven by power injection. Next step is to achieve the best balance between network topology and reliability to figure out the known problems of Ethernet like delay and packet loss. We improved the ITU-T G.8032, the Ethernet ring protection mechanism, to fit the automotive Ethernet network. The target is to make the network system enable to tolerate more than one failure (including node failure), and to ensure the correctness of data transmission on each node. Results showed that an effective algorithm considering with some important factors like network availability and fault model actually affects the optimal choice of network structure design. To conclude, this study hopes to lay the foundation for the new generation vehicle network to provide engineers a reference for vehicle network design.
- 17:10 Toward designing efficient Service Discovery Protocol in Vehicular Networks
- Nowadays, it can be seen that there is an increasing interest in the field of vehicular networks due to its important applications. These applications depend mainly on the service discovery protocols which show the need for giving more work and effort to design an efficient VANET service discovery protocol. In fact, little studies have been conducted in this field. Therefore, this paper attempts to highlight some directions that can be considered for designing service discovery solution for VANETs. To explore these directions, the paper provides a literature review for the earlier studies and presents a qualitative analysis of them in order to provide some recommendations for the best design issues. This is can be considered as a step toward designing efficient protocol and may encourage researchers to contribute more in this field.

- 15:50 Tracking Uncertain Moving Objects using Dynamic Track Management in MHT
- Laser range finder (LRF) has been widely used for detecting and tracking moving objects. In autonomous navigation, LRF provides reliable data of moving objects surrounding the vehicle for obstacle avoidance. Data association is a crucial process for a successful moving objects tracking. In urban area, objects tend to move in various directions, thus increasing the possibility of incorrect data associations. In this paper, a reliable dynamic track management based on Multiple Hypothesis Tracking (MHT) method is proposed. The Interacting Multiple Model (IMM) with Kalman filter provides extra information for track management process which increases the performance of data association. Simulations were conducted to evaluate the proposed track management in various scenarios to deal with the creation of new track, track deletion and detection of cross track. The results suggested that the proposed method produced acceptable results, reflecting the accuracy of object identification for all moving objects in all tested scenarios.
- 16:10 LESY-ECO: Learning system for eco-driving based on the imitation
- In this paper, we propose a learning method for eco-driving based on imitation. The system uses Data Envelopment Analysis (DEA) in order to calculate the driving efficiency from the point of view of the fuel consumption. The input and output parameters have been selected taking into account the Longitudinal Vehicle Dynamics Model. This technique allows us to notify the user about who is the most efficient driver close to him or her and to suggest the imitation of the behavior of such driver. The proposed method promotes learning by observation and imitation of efficient drivers in a practical rather than theoretical way such as attending eco-driving lessons. The DEA algorithm does not depend on the definition of a preconceived form of the data in order to calculate the efficiency. The DEA algorithm estimates the inefficiency of a particular DMU by comparing it to similar DMUs considered as efficient. This is very important due to the dynamic nature of the traffic. A validation experiment has been conducted with 10 participants who made 500 driving tests in Spain. The results show that combining eco-driving lessons with the proposed learning system, drivers achieve a very significant improvement on fuel saving (15.82%).Presenter bio: Víctor Corcoba got his Computer Engineering degree from the University of Granada in 2009 and and the Ph.D. degree in telematic engineering from the Carlos III University of Madrid, Leganes, Spain, in 2014.

- 16:30 A Reference Architecture for CISS/CDAS within the Field of Cooperative Driving
- The V2V communication is a promising technology aiming at the growing demands on safety, comfort and efficiency. A variety of research projects demonstrate the expandability of the V2V communication across the boundaries of current industry standards. The authors divide the expandability into two key aspects: collective scene description and cooperative maneuvers. This article combines the expandability of the V2V communication with systematically deduced essential automotive requirements and the challenges of a distributed decision making process. That leads to a reference architecture for cooperative driver assistance systems (CDAS) and cooperative integrated safety systems (CISS), uniting the flexibility for several implementations and a defined focus by the help of clear modules and interfaces. This article verifies the reference architecture using a cooperative merging onto a highway with a focus on the diversity of feasible implementation. The reference architecture arranges the field of research in separate problems and stimulate discussions about the proposed interfaces as an important step to future standards. Further research will gradually address the separate modules to establish the performance of CDAS/CISS and evaluate several concept variants.Presenter bio: -2014-on going engineer Volkswagen group research, development of cooperative safety systems - 2010-2014 Phd-student, technical University Carolo-Wilhelmina of Braunschweig, Titel of Thesis: "Objectdatafusion of environmental sensors and V2V in order to develop intelligent safety systems for front collisions" - 2004-2010 studies in engineering (mechatronics), Otto-von-Guericke University of Magdeburg
- 16:50 A Probabilistic, Multivariate Approach for Object Recognition in Thermal Infra-Red Images
- For any task that autonomous vehicles may encounter in unstructured outdoor environments a reliable vision system is a key point for success. That is especially true with an autonomous convoy, where each vehicle has to track and follow the one in front. When applying a multivariate based approach for object detection, dimensional reduction of processed data is a vital part of any algorithm. Based on probabilistic classification into two classes (positive and negative) three different approaches for dimensional reduction are examined in this paper: The first method transforms new images in two reduced principal component analysis (PCA) spaces, derived from negative and positive training images respectively. The second approach calculates a mutual PCA space from all training images and the third strategy uses linear discriminant analysis (LDA) for data reduction. In these reduced spaces image classification is done with the Gaussian classifier. Through experiments it is shown that classification in the mutual PCA and the LDA space result in fewer errors and a more reliable class assignment. Furthermore, the use of LDA is more robust if confronted with incomplete training data. Finally it is shown that a confidence approximation using Gaussian processes can, if trained, identify positive and negative images and evaluates untrained images with the appropriate uncertainty.Presenter bio: David Spulak received the degree ‘Bachelor of Science in Engineering’ in 2012.

- 17:10 Cooperative Autonomous Driving using Cooperative Perception and Mirror Neuron Inspired Intention Awareness
- In this paper, we present the concept of cooperative autonomous driving using cooperative perception. The cooperative perception can provide upcoming traffic situations ahead, even beyond line-of-sight and field-of-view. From a control perspective, a spatial map for navigation planning is extended up to the boundary of connected vehicles in a see-through manner. By leveraging this augmented perception capability, a better driving decision can be accomplished in terms of traffic flow efficiency and safety improvement. For this purpose, we propose a mirror neuron inspired intention awareness algorithm along with planning and control methods using the algorithm.

- 10:40 Priority-based Intersection Control Framework for Self-Driving Vehicles: Agent-based Model Development and Evaluation
- Development of in-vehicle computer and sensing technology, along with short-range vehicle-to-vehicle communication has provided technological potential for large-scale deployment of self-driving vehicles. The issue of intersection control for these future self-driving vehicles is one of the emerging research issues. Contrary to some of the previous research approaches, this paper is proposing a paradigm shift based upon cooperative self-organizing control framework with end-user responsibility. Distributed vehicle intelligence has been used to calculate each vehicle's approaching velocity. The control mechanism has been developed in an agent-based environment. Self-organizing agent's trajectory adjustment bases upon a proposed priority principle. Testing of the system has proved its safety, user comfort, and efficiency functional requirements.

- 11:00 A Generic Load Balancing Framework for Cooperative ITS Applications
- The deployment of cooperative ITS applications is due to start as soon as 2015. Large investments in the roadside unit (RSU) infrastructure will be necessary to create a dense network and accommodate an increasing number of services, leading to a discussion about the trade-off between distributed processing and storage solutions on the RSU nodes and the centralized alternative. A strictly central solution might not be scalable, whereas the decentralized approach faces the problem that load in the form of CPU and memory usage may be unequally distributed among the nodes, causing performance bottlenecks on some of the RSUs. This work presents a solution for this problem, in form of a generic framework that balances the load between the nodes and reduces in this way the RSU costs. The interactions are based on a flexible coordination pattern for load balancing that is realized using customizable containers provided by a distributed systems middleware. This mechanism is applied to a probe data collection scenario in which individual messages are aggregated by RSU nodes, causing both CPU and memory load. Simulation results illustrate the operation in dynamic load situations.Presenter bio: Stefan Craß is a research assistant at the Institute of Computer Languages of the Vienna University of Technology.

- 11:40 A Platoon Speed-Adjusting Algorithm for Autonomous Vehicles to Ensure Uninterrupted Traffic Flow on Arterials
- This paper presents the microsimulation results obtained from two scenarios of applying connected vehicles and Intelligent Transportation Systems (ITS) to intersection control. Different from other studies in the literature, the algorithm developed in this study controls the speeds of vehicle platoons approaching an intersection as opposed to traffic signal timing. The simulation results for both scenarios are promising. Significant reductions in queue length, number of stops and delay were observed. Marginal increase in vehicle platoon speed was also observed.
- 12:00 Highway Traffic Flow Measurement by Passive Monitoring of Wi-Fi Signals
- Motivated by the fact that a significant number of personal mobile devices are carried into vehicles and that the majority of those devices continuously emit Wi-Fi frames, we investigate the feasibility to use theses transmissions for road traffic analysis. Background transmissions are emitted by the majority of Wi-Fi-enabled devices by means of so called probe requests. We show by a real-world measurement on an Austrian motorway that a sufficient number of probe requests can be received in order to re-identify devices traveling between two locations and to estimate travel times. Our results show that by proper post-processing of measurement data, the number of generated travel time estimations per hour are comparable with conventional traffic detectors. We show how to increase user privacy by pruning parts of the Wi-Fi device identifier. This way we avoid a unique relation between a travel time measurement and a Wi-Fi device, which could potentially be linked to a user. Using such ambiguous identifiers has an impact on travel time measurements. Based on our measurements we show a trade-off between privacy and accuracy of the results.Presenter bio: Paul Fuxjaeger is a researcher at the Telecommunications Research Center Vienna (FTW) where he works in the field of wireless mesh networks and intelligent transport systems.

- 10:20 Automated Planning of Charge Processes for Privately Owned Electric Vehicles
- Following the vision of decentrally generated and locally out-balanced renewable electric energy the research project econnect Germany investigates the end user acceptance of Vehicle2Grid and Grid2Vehicle applications. Clearly, the algorithm used to compute the charging/discharging of individual batteries in electric vehicles (EV) will be an essential factor for end user acceptance. This is because it controls the achievable driving range and the cost savings for the individual user of an electric vehicle. Additionally, the algorithm has to allow for an effective control by the energy provider to compensate for the natural fluctuations of wind and solar energy in the region. Furthermore, as the final authority to decide about charging/discharging needs to be the battery management system of the EV, it is a natural choice to embed the algorithm in an electronic control unit of the car. This paper presents an algorithm designed to meet these requirements and demonstrates that it scales down to the low computing power of embedded automotive systems.Presenter bio: Tillmann Nett was born in 1981 in Bonn, Germany.

- 10:40 Improving Energy Distribution for EV Charging Over Public Lighting Systems
- The success of the charging infrastructure deployed for Electric Vehicles (EV) charging should not only rely on the size of the network, but in the proper management of the resources available. When the charging infrastructure is shared in order to provide different services, the constraints imposed by the System Operator (SO) of the electric network must always be respected to guarantee the simultaneous operation of all the services provided. TeleWatt is an innovative EV charging infrastructure which is shared with the electric network deployed for the Public Lighting System (PLS). The first approach of this solution remained quite conservative, as the main scope was to prove that the PLS and the EV charging system could operate simultaneously. The present work proposes adaptation of well-known on-line scheduling policies to the infrastructure of TeleWatt, which is limited by the constraints of the PLS network. This allows to treat the charge of EVs as tasks and manage them according to different priorities. This work demonstrates how the performance of the system could be improved without any physical changes in the infrastructure, but just by the way that the resources are managed.Presenter bio: Mario Alvarado-Ruiz is a PhD candidate at Telecom ParisTech in France.

- 11:20 Two-stage Mechanism Design for Electric Vehicle Charging Involving Renewable Energy
- Integrating massive electric vehicles (EVs) into the power grid requires the charging to be coordinated to reduce the energy cost and peak to average ratio (PAR) of the system. The coordination becomes more challenging when the highly fluctuant renewable energies constitute a significant portion of the power resources. To tackle this problem, a novel two-stage EV charging mechanism is designed in this paper, which mainly includes three parts as follows. At the first stage, based on the knowledge of future energy requests and considering the elastic charging property of EVs, an offline optimal energy generation scheduling problem is formulated and solved in a day ahead manner to determine the energy generation in each time slot next day. Then at the second stage, based on the planned energy generation day-ahead, an adaptive real-time charging strategy is developed to determine the charging rate of each vehicle in a dynamic manner. Finally, we develop a charging rate compression (CRC) algorithm which tremendously reduces the complexity of the problem solving. The fast algorithm supports real-time operations and enables the small-step scheduling more efficiently. Simulation results indicate that the proposed scheme can help effectively save the energy cost and reduce the system PAR. Detailed evaluations on the impacts of renewable energy uncertainties show that our proposed mechanism achieves a good performance in enhancing the system fault tolerance against uncertainties and the noises of real-time data.Presenter bio: Ran Wang currently works as an assistant professor at College of Computer Science and Technology, Nanjing University of Aeronautics and Astronautics.

- 10:20 TCP-like congestion control for broadcast channel access in VANETs
- Broadcasting of position and movement information in vehicular ad hoc networks is essential for achieving an awareness of connected vehicles about their environment. If a vehicle broadcasts its position several times per second, then other vehicles can use this information as input for advanced driver assistance systems. Vehicular communication based on the 802.11p standard in the 5Ghz band provides a channel for dissemination such awareness information. However, the channel access is not coordinated among the participating vehicles and, thus, a congestion of the channel is possible, i.e. a situation where access delays rise and packet reception rates drop. An initial ETSI standard on congestion control tries to solve the problem by assigning transmit rate limits depending on channel load. We investigate here an alternative solution inspired by the congestion control mechanism of TCP. We describe necessary adaptions of the TCP congestion control to a single-hop broadcast communication and evaluate pros and cons in comparison to a fixed-state congestion control by extensive simulations. Our results exemplify typical differences in effective reception ranges and update intervals, and show performance advantages of adaptive DCC algorithms.Presenter bio: Stefan Ruehrup is senior researcher at the Telecommunications Research Center Vienna (FTW), where he manages the Communication Networks Area and works in the field of mobile communications and ITS.

The proposed radiators are optimized in terms of unhindered EMC function, even when other vehicle electronic systems are involved. Moreover, to attain reliable designs, a generalized explicit method of scalable accuracy is developed. The 3-D hybrid schemes blend a stencil-based finite-volume time-domain and a Fourier-Chebyshev pseudo-spectral time-domain algorithm that split the overall space into smaller areas. So, the resulting discretization yields highly precise and computationally affordable simulation models, devoid of mesh errors. Numerical results, compared with reference or measurement data, reveal the benefits of the miniaturized antennas and substantiate their potential applicability.Presenter bio: Traianos V.

- 11:00 Analytical model of RTT-aware SCTP
- Connected vehicles are promoted with the use of different communication technologies for diverse applications. A host with multiple network devices is referred to as a multi-homed node. Stream Control Transmission Protocol (SCTP) is an IETF standard which supports multi-homing. However, original SCTP multi-homing functionality is only used when the primary address becomes unavailable. This paper presents an analytical model for a modified SCTP with multi-homed hosts, which selects the primary network address using a utility function based on minimum round trip time.
- 11:20 A Network Access Control Solution Based on PANA for Intelligent Transportation Systems
- The growing interest in Intelligent Transport Systems (ITS) together with the specification of standards carried out by the International Standards Organization (ISO) and the European Telecommunications Standards Institute (ETSI) to define a common ITS reference communications stack have paved the way to new research lines about vehicular networks. In this sense, the application of Internet Protocol version 6 (IPv6) communication technologies is currently living a strong impulse in order to evaluate the application to well-known Internet technologies to the vehicular environment. Currently, most efforts have focused on the definition and testing of ITS applications operating over IPv6 communication technologies. Unfortunately, little attention has been payed to the security needed in these scenarios to ensure that only authenticated systems are granted access to vehicular services in Vehicular-to-Infrastructure (V2I) infrastructures like, for example, the network access service. This paper addresses this problem by improving the ISO/ETSI ITS communication architecture to support network access control functionality. The proposal is based on standardized technologies like the Protocol for Carrying Authentication for Network Access (PANA), which is the most representative contribution of the Internet Engineering Task Force (IETF) to this security problem. Moreover, this proposal has been tested in a real environment in order to validate its performance and suitability for ITS.Presenter bio: Fernando Bernal received an MSc in Computer Science Engineering and an MSc in Advanced Information and Telematics Technologies in 2008 and 2009, respectively; all of them from University of Murcia, Spain.

- 11:40 Cellular-based Vehicle to Pedestrian (V2P) Adaptive Communication for Collision Avoidance
- Road safety is one of the most important applications of vehicular networks. However, improving pedestrian safety via vehicle-to-pedestrian (V2P) wireless communication has not been extensively addressed. In this paper, our vision is to propose a method which enables development of V2P road safety applications via wireless communication and only utilizing the existing infrastructure and devices. As pedestrians' smartphones do not support the IEEE 802.11p amendment which is customized for vehicular networking, we have initiated an approach that utilizes cellular technologies. Study shows potential of utilizing 3G and LTE for highly mobile entities of vehicular network applications. In addition, some vehicles are already equipped with cellular connectivity but otherwise the driver's smartphone is used as an alternative. However, smartphone limited battery life is a bottleneck in realization of such pedestrian safety system. To tackle the energy limitation in smartphones, we employ an adaptive multi-level approach which operates in an energy-saving mode in risk-free situations but switches to normal mode as it detects a risky situation. Based on our evaluation and analysis, this adaptive approach considerably saves electrical energy and thus makes the cellular-based road-safety system practical.Presenter bio: Background and work experience in software engineering, master's degree in embedded and real-time software engineering.

- 12:00 Real Time Traffic Accident Detection System using Wireless Sensor Network
- Automatic vehicle accident detection is a life-saving application that is vital in today's high speed motorways. In case of motorway accidents, notification to the proper authorities must be done efficiently and expediently. The main objective of this paper is to create a Real Time Traffic Accident Detection System (RTTADS) using Wireless Sensor Network (WSN) and Radio-Frequency Identification (RFID) Technologies. This paper explains the hardware prototype setup for RTTADS, the algorithms used, the advantages and the limitations of the entire system. Also the configuration of the setup and application software is elaborated. Sensors installed in a vehicle detect the accident's location, the vehicle's speed just before the accident and the number of passengers in the vehicle. The sensors then send an alert signal to a monitoring station. The monitoring station, in turn, tracks the location where the accident has occurred and directs casualty alert to the authorities concerned.

By observing the dynamics of such automata, we can devise optimal rules that may relieve the traffic congestion, and increase security. Last but not least, this model is an algorithmic framework to devise novel algorithms that use vehicular network and communication between cars.
- 11:00 Development of an omni-directional mobile robot with two automated guided driving modules
- An omni-directional mobile robot is developed by using two automated guided driving modules in a tandem layout. Each module contains a suspension-like mechanism on the upper layer and a rotatable driving chassis with powered wheels on the lower layer. The suspension layers of two modules are fixed to the robot frame, and each chassis can rotate freely about a vertical axis through its centers by a passive rotation joint. A kinematics model is built for this mobile robot, and a cross coupling control algorithm is developed for its omni-directional movement. An on-board camera is mounted on the center of the robot to measure its pose deviations with respect to the guide paths. In order to improve the accuracy of vision measurement, a plane target with the grid pattern is used to calibrate the intrinsic, distortion and extrinsic parameters of the on-board camera. This camera is then used to record the pose deviations in the experiment of the omni-directional motion, the results of which show the feasibility of that the combination of two guided driving modules can be used to improve the maneuverability of mobile robots.

- 13:30 Enhancement of Suspension System Performance of Heavy Vehicles through the Optimized Parameters using Particle Swarm Technique
- Particle swarm optimization (PSO) algorithm has attracted significant consideration among a lot of modern heuristic optimization techniques. Nowadays, PSO is widely applied in various scientific and engineering fields. This paper concerns the investigation of design the passive suspension system parameters of heavy vehicles using the non-linear PSO algorithm, for the first time. A mathematical model and the equations of motion of a passive quarter vehicle suspension are derived and simulated using Matlab/Simulink software. The proposed PSO algorithm aims to minimize the dynamic tyre load generated by vehicle-pavement interaction as the objective function with constraint the natural frequency of the unsprung mass. It is applied to solve the nonlinear optimization problem to find the tyre stiffness, suspension stiffness and the damping coefficient of the passive damper by detecting the optimal problem solution through cooperation and competition among the individuals of a swarm. Suspension performance criteria are evaluated in the time and frequency domains in order to quantify the obtained parameters under bump and random road disturbance. Compared with the passive suspension system optimized using the Genetic Algorithm (GA), the proposed PSO algorithm improves the suspension performance effectively and gives a superior performance.

Emergency Vehicles (EV) such as ambulances, malfunctioning or broken cars, and accidents may appear at any time at any spot in the traffic. Less likely but not inevitably, there might be fires, terrorist attacks, earthquakes which will cause panic behaviour and unexpected traffic congestion. The challenge in our framework is the proposition of a range of innovative solutions for intelligent and efficient traffic management in Emergency and Disaster Management (EDM). In this paper, we propose a multilevel infrastructure which is dynamically reconfigured and thus allows a trade-off between total cost, energy consumption and quality of service in EDM.Presenter bio: Pr.

- 14:10 Vehicular Traffic Predictions from Cellular Network Data - A real world case study
- The emergence of mobile technologies provides the opportunity to carry mobility field into the smart city arena. Transportation data are key factors for improving mobility services: traditional approaches to compute urban dynamics, mobility patterns and real-time vehicular traffic situations are based on cameras, on-road sensors or emergency calls, while more modern approaches merge social warnings and mobile data in collaborative navigation systems to detect traffic congestions. In this paper, we present a novel "passive" approach for gathering, processing, and predicting real-time vehicular traffic conditions from cellular network data. The approach exploits the regression statistical tool to detect whether significant statistical models exist to describe correlations between cellular network events and vehicular traffic situations. The paper discusses the regression model we derived and it presents the results obtained by validating our approach, in a real industrial setting and for the Milan city, against the well-known traffic solutions: Autostrade.it, InfoBlu and Google.Presenter bio: Davide Tosi received his MSc in Computer Science (2002) and his PhD in Computer Science (2007) at the University of Milano Bicocca.

- 14:30 Towards sustainability in multi-modal urban planners
- Public transport systems in modern cities are the key to create the sustainable citizens' mobility of the future where the private vehicle is needed only for transportations that public transport cannot be afforded. Supporting the use of the public transport in the cities is one of the main objectives planned by the European Union for next years, making an important effort to reach a decrease of twenty percent for emissions of greenhouse gases derived from urban mobility before 2020. But for achieving this goal is necessary to make a change in the perception that citizens have about transport systems. Current travel and journey planners may not consider some variables that may contribute to improve the perception of the citizen when he has to face mobility into the urban areas of the city. Besides the transport timetable, the citizen schedules or the travel costs, the route planners have to improve both the quality of the proposed planned mobility and the performance of the public transportation system. We study different factors that have to be taken in consideration to develop new planners based not only the optimization of time, costs, distance or the number of transport changes, but also the elements that can help to make the travel more comfortable to users such as knowing the position of transport vehicles or giving advices to make health, safety trips.Presenter bio: Researcher in scientific instrumentation automation and intelligent transport system.

- 13:30 Current Ripple Evaluation in Dual Three-Phase Inverters for Open-End Winding EV Drives
- Ac motor current ripple in electric vehicles is source of electromagnetic interferences and audio noise, from the inverter-motor power connection cables and from the motor itself. By increasing the inverter switching frequency the ripple amplitude is reduced, but the drive efficiency decreases due to the proportionally increased switching losses. A viable solution to reduce the current ripple amplitude is to introduce a multilevel inverter instead of a standard two-level (2L) three-phase inverter. A simple and effective way to achieve a three-level (3L) inverter in battery-supplied electric vehicles consists of using two standard three-phase 2L inverters with the open-end winding mo¬tor connection. In this paper the peak-to-peak ripple amplitude of the dual-2L inverter is evaluated and compared with the corresponding ripple of the single 2L inverter, considering the same volt¬age and power motor ratings. The ripple analysis is carried out as a function of the modulation index to cover the whole inverter modulation range.Presenter bio: Gabriele Grandi received the M.Sc.

- 14:10 Centralized Cooperative Spectrum Sensing with Multiple Antennas Over Imperfect Feedback Channels
- In this paper, we study the performance of a cooperative spectrum sensing (CSS) scheme over imperfect feedback channels, where N secondary users (SUs) collaborate in order to enhance the detection probability of a primary user (PU). The sensing process is divided into two phases: In the first phase each SU, which is equipped with multiple antennas, independently detect the PU signal. In the second phase, the SUs' local decisions are sent via erroneous and orthogonal feedback channels to a fusion center (FC), where a final decision is made. We utilize Bayesian criterion which accounts for the costs of misdetection and false alarm. Quasi-Newton method is employed to obtain the optimal number of antennas for a given SNR and vice versa. Our simulation results concur the mathematical derivations and validate the optimality of quasi-Newton method. We further show that the derived optimal fusion rule outperforms the OR rule, AND rule and MAJORITY rule.Presenter bio: Graduate student at Khalifa University of Science, Technology and Research.

- 14:30 Analysis for Interference-based Capacity of Vehicular Ad Hoc Networks
- In view of the various quality of service (QoS) requirements raised by the different applications of vehicular ad hoc networks (VANETs), the characteristic of communication capacity is vital for the design and implement of the Intelligent Transportation System (ITS). Although some scaling law-based results had already been obtained for VANETs to describe the general performance changing pattern when the total number of network nodes goes to infinity, they cannot be used directly to estimate the actual capacity of a communication pair or the entire network. To make up with this disadvantage, a interference-based capacity analysis is finished in this paper for the VANETs scenario. For representing the unique constraint of inter-vehicle distance, which directly affects both the signal and interference power decaying, the car-following model is used to describe the vehicles' mobility feature. Based on that, a series of probability characteristics are derived for a general interfering scenario, which finally leads to the expected VANET capacity. We believe the new results obtained in this paper will provide useful guidelines for the deployment of future VANETs.
- 14:50 Chaotic Quantum Particle Swarm Optimization for Parameter Adjustment in Green Cognitive Radio
- In this paper, we study parameter adjustment to maximize the energy efficiency of green cognitive radio. Since the problem of parameter adjustment can be looked as a complex discrete optimization problem，a chaotic quantum particle swarm optimization (CQPSO) was proposed to solve it. CQPSO integrates the characteristics of chaos and quantum theory to particle swarm optimization, which makes it have strong search ability. Chaotic mutation is introduced to avoid premature convergence and keep diversity. Quantum computing has excellent features used to speed up the optimization and enhance the search ability of CQPSO. We design a green cognitive radio system for performance analysis, and a novel parameter adjustment method based on CQPSO is derived. The proposed method has a good performance in terms of convergence rate and convergence accuracy, and can search an optimal solution for parameter adjustment in green cognitive radio network. Through simulations, we can get a conclusion that the proposed CQPSO can improve the energy efficiency and meet the users' quality of service (QoS) needs.

- In this paper we investigate an event-driven Inter- Vehicle Communication protocol to mitigate shock waves in dense traffic situation. From previous work we know that flooding or frequent beaconing require excessive network resources. To overcome this limitation we focus on an efficient message exchange mechanism requiring as few network resources as possible, while still providing timely and accurate traffic information. We designed Density Redistribution through Intelligent Velocity Estimation (DRIVE), an event-driven Inter-Vehicle Communication protocol that learns about traffic conditions ahead and recommends optimal velocities in order to prevent the formation of vehicular shock waves. We demonstrate that our approach of reacting in case of traffic fluctuations leads to significant improvements in overall traffic flow. Furthermore we show that even a low number of equipped vehicles is sufficient to achieve this target.Presenter bio: 2011 - M.Sc in Information and Computer Science 2015 - PhD in Computer Science from the University of Luxembourg

- 14:10 Driver Behaviour Profiling using Smartphone Sensory Data in a V2I Environment
- Road traffic accidents prevention and mitigation are important issues that appear on top of the priority list of many countries around the world today. Many measures and approaches have been put in place in terms of policy level as well as technical level. Driver behaviour is one of many key factors that should be seriously considered to improve road safety. This paper proposes a method for driver behaviour profiling using sensory data on smartphones in a vehicle-to-infrastructure environment. Based on driving behaviours with the most risk to causing accidents, the profiling algorithm takes into account sudden driving events which occur during a journey to categorise drivers into different profiles according to their safety levels. The profiling algorithm offers the flexibility to adjust the parameters weightings in order to put an emphasis on specific driving events for different scenarios and applications. The impact on vehicle- to-infrastructure is that the stored driving profiles can be used to generate a norm for a given road section. Approaching vehicles deviating from the norm can be notified in real-time. Moreover, localised dangerous driving events can be clustered together to form a potential blackspot which can be deployed as an advanced warning for approaching vehicles as a location based service. As a result, the risk of road traffic accidents can be reduced. Real-world driving data was collected over two major routes in Thailand with four distinct profiles and five major factors to road accidents.Presenter bio: Dr. Chalermpol Saiprasert received his masters and PhD from Imperial College London in Electrical Engineering in 2010.

- 14:30 Intelligent traffic control and optimization with cooperative systems on the eHighway
- Making the traffic more efficient, safer and ecofriendly are important global aims for a sustainable future. To reach these goals electro mobility and V2X-communication are important key technologies. To reduce the emissions the automobile industry presented a quantity of electric car models during the last years. While the range of electric cars with about 150 km is adequate for inner city use, the battery-systems are not suitable for truck purpose. To enable electric driving also for long distance heavy goods vehicles (HGV) SIEMENS developed the eHighway technology. While using the overhead contact line it is possible to continuously provide electric energy to the vehicle and thus drive environmentally cleaner and more energy efficient. With the V2X-equipment of the eHighway and the connection to the traffic control centre (Conduct+) it is possible to increase the safety, the road capacity and to provide additional information for eHighway–user and all other V2X-equipped road users. While using the information from existing road sensors combined with the V2I-status-information of the road users, Conduct+ generates a holistic overview of traffic events. Via I2V Conduct+ advises the participants about changes in the traffic flow using in-vehicle signage. On a purpose-build test track SIEMENS and the DLR are proving the interaction of Conduct+, eHighway-infrastructure and V2X-equipped-eTrucks. This paper provides an insight into the eHighway-components and the functionality of the system components which enables the accumulation of traffic-data to enable an intelligent traffic control using V2X.
- 14:50 Analyzing Cooperative Lane Change Models for Connected Vehicles
- This paper examines intelligent lane change models based on the cooperation among connected vehicles for traffic management and travel time optimization. Lane change decisions and speed controls could be coordinated and optimized to reduce overall braking and achieve greater traffic throughput. In an effort to design (D-CLCA) a distributed cooperative lane change assistant within the European Commission's project REDUCTION*, this paper describes the requirements associated with an optimal lane change behavior, and evaluate existing lane change models based on these requirements. We have evaluated these models for travel times, fuel consumptions, number of lane changes and total braking for all the vehicles globally on the considered road segment. For evaluations, we have developed traffic simulations using different traffic densities for both symmetric and asymmetric lane changes and different levels of cooperation among drivers. Our empirical analysis show that an optimal lane change model should optimize the proposed evaluation criteria for all the vehicles simultaneously. These results will be used to develop an efficient distributed and cooperative lane change assistant.

- 15:50 Autonomous Vehicle Public Transportation System
- Under active research, technology of autonomous vehicles (AVs) is getting mature and many AVs will run on the roads in the near future. With the support of vehicular ad-hoc network, AVs become connected. The ability of high degree of control allows AVs to respond to instantaneous situations cooperatively with high efficiency and flexibility. In this paper, we propose a new public transport offering point-to-point services with ride sharing. It manages a fleet of AVs to accommodate a number of transportation requests. Due to the unmanned nature, the AVs operate by following the routes instructed by the control center of the system. With proper scheduling, the control center assigns the transportation requests to appropriate AVs in order to minimize the total operational cost. We formulate the scheduling problem with a mixed-integer program. We study the system performance with a typical artificial scenario. Our results show that ride sharing can effectively lower the operational cost and increasing the vehicular capacity can further enhance the system performance.
- 16:10 An Analysis Model of Queue Length Fluctuation at Signals Using Vehicle Trajectories
- Floating car systems have attracted much attention. In particular, trajectory information of vehicles, which cannot be obtained in legacy traffic monitoring systems, would be significant for more detailed and precise traffic prediction. In this paper, we focus on vehicle queues formed in front of intersections and present a model that analyzes the dynamics of their length using vehicle trajectory information. In general, a queue grows in a red phase of the traffic signal cycle and shrinks in a green phase. We assume that vehicles arrive at a signal with a Poisson process, and estimate the queue length for each signal cycle. Our method was evaluated using a traffic simulator where the real field data were injected. Evaluation results have shown that the queue length could be estimated and the mean error was about 5 vehicles, which is acceptable compared with the whole queue sizes.Presenter bio: Tomoyuki Tange graduated from Osaka University, Department of Information and Computer Sciences in 2014.

To address the security issues and to reduce payload overhead we are proposing a novel method for classification of VANET messages along with a Multi-hashed Binary Tree (MuBT) Algorithm. This algorithm verifies the identity and authenticity of the vehicles and messages exchanged. In addition to this, the concept of public cloud is used to store the location of vehicles, keys, messages and certificates involved in VANET communication. This ensures any time data accessibility from anywhere and helps to track the messages when necessary. The messages exchanged and the Transient Tickets (TTs) used in VANET communication is encrypted using the geolocation key of the RSU. The use of geolocation key provides location confidentiality against vehicles outside the zone and also ensures that a message can be sent only if the vehicle is physically present in the location.Presenter bio: Dr. Manohara Pai M.M. is currently Professor of Information and Communication Technology and Associate Director of Innovation Centre, Manipal Institute of Technology (MIT), Manipal University, Manipal, Karnataka, India.

Today's cars are becoming computer controlled systems in which the driver's commands, car's motion and trajectories can be logged and transmitted to the control center by means of cellular communication, . Furthermore, local dynamic map involving the digital road map, speed limits and average link travel speed can be used to match the driving behavior with respect to the normal conditions of the static and dynamic traffic. On the other hand, driver scoring enforces better driving and operation of the vehicles in the fleets. Fleet managers can take corrective actions to the drivers according to their driving quality. In this paper, we define a safety oriented driving quality index and the corresponding architecture which is scalable up to 50.000 vehicles.

The proposed algorithm unifies the wheel slip controller and the torque blending functions into a single framework. The capability of handling energy performance metrics, actuator constraints and dynamics, represents the main advantages of this approach. Simulation studies demonstrate that, in comparison with state-of-art solutions, the proposed control strategy is able to improve the wheel slip and torque tracking by more than 20%, with minor penalization in the energy recuperation.

- 15:50 Minimum Real-Time Chunk Delay for Active Safe Driving in Vehicular Ad-Hoc Networks
- The active safe driving application, one of the important trends in future wireless mobile applications, offers real-time video streaming services and real-time emergency messages (EMs) to improve the driving safety in the intelligent transportation system (ITS). As the required (or shared) video and EM quality increasing, the constraints of packet delay, packet loss rate and the required bandwidth of packet transmissions become critically in Vehicular Ad-hoc NETwork (VANET). Multicasting is thus adopted to reduce the bandwidth waste rate while a sender wants to send real-time videos to a group of receivers. Although the multicasting VANET can adopt the retransmissions of lost chunks, it yields a long multicasting delay and wastes bandwidth for re-sending video chunks to the receivers that have successfully received chunks. This paper thus proposes a Peer-to-Peer (P2P) overlay network to cooperate with the multicast VANET, namely the minimum Delay-Guarantee chunk Reloading approach (DGR), to reload the lost or unconfirmed chunks timely. In DGR, a chunk with the least delay to the lost-chunk node is selected as the optimal compensating chunk. Numerical results demonstrate that DGR outperforms the compared approaches in successful chunk reload rate, average chunk delay, and chunk delivery ratio. Clearly, the retransmission-based multicasting and the random chunk-selection mechanism lead to obvious long delay and large bandwidth waste rate. DGR minimizes the chunk compensation delay and bandwidth waste rate.
- 16:10 Performance Evaluation of Receiver-based GeoRouting Protocols for Infotainment Services in VANETs
- Inter-Vehicle Communication (IVC) is a promising technology, which enables Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communications, to improve driving safety, reduce traffic congestion and support information services in vehicles. GeoNet project brought the IVC one step further by enabling transparent IP connectivity between vehicles and the infrastructure. Integrating the IVC with existing infrastructure over IPv6 will also enable the use of infotainment services. Specifications produced by the GeoNet project have been incorporated into several ETSI standards, which define the geonetworking layer and the IPv6-over-geonetworking adaptation layer. In this work, we focus on the georouting module of these standards. The default georouting protocol proposed in these standards is a sender based Greedy Forwarding protocol. We investigate the performance of this protocol for infotainment services and compare its performances with several alternative receiver-based georouting protocols. Our experiments shows that receiver based protocols perform better in most of the cases.
- 16:30 Minimizing Emergency Message Collisions and Maximizing Network Throughput in IEEE 802.11p Vehicular Wireless Network
- IEEE 802.11p is proposed as the VANET wireless MAC interface for the transmissions of emergency messages in V2V and V2I Communications. However, in a high mobility VANET, QoS of both the emergency message (EM) and handoff transmissions suffer from high collision probability of the contention-based media access mechanism and high interference exhibiting near the cell-edge that encodes a low coding rate of the Adaptive Modulation and Coding (AMC) scheme. Thus, this paper proposes an efficient MAC for IEEE 802.11p to solve above critical issues, in which the approach consists of three main mechanisms: 1) the Sigmoid-based CW Decrease (SWD) algorithm, 2) the Dynamic Initial CW (DIW) algorithm, and 3) Relay-based partition Collision Domain for Handoffs (RCDH). Note that the CW decrease formulation is determined based on the Sigmoid function. Numerical results demonstate that the analysis results are close to the simulation results, and thus justify the correctness of the mathematical analytical model. In addition, the proposed approach outperforms the compared approaches (including the IEEE 802.11p std.) in EM transmission delay, collision probability, throughput, and MAC frame dropping probability.Presenter bio: Ben-Jye Chang is currently a full professor of the department of Computer Science and Information Engineering, National Yunlin University of Science and Technology, Yunlin, Taiwan.

In order to minimize the interference between macro- and femto base stations, we use a constrained optimization technique to optimally allocate bandwidth and power to macrocell and femtocell UEs. Matlab's CVX library is used to solve the optimization problem. Depending on the UEs' position from their serving base station (macro or femto) and their demand for higher data rates than minimum requirement data rate, the optimal power and bandwidth is assigned to each base station.Presenter bio: Fjolla Ademaj received the B.Sc. degree in electrical engineering and M.Sc. degree in telecommunications from the FECE, University of Prishtina, Kosovo, in 2011 and 2014.

- 17:10 Vehicle Routing with Backup Provisioning Using Wireless Sensor Infrastructure
- Intelligent transportation systems are currently under strong research and are expected to promote the emergence of new solutions for urban transportation networks. Here we introduce a variant of the open vehicle routing problem, called vehicle routing with backup provisioning, where the possibility of reacting to overloading/overcrowding of vehicles in certain stops is considered. This is based on the availability of vehicle load information in real time, which can be captured using wireless sensor technologies. A heuristic algorithm to plan routes is also proposed. Results show that vehicle routing with backup provisioning can be a way of providing sustainable urban mobility with efficient use of resources, while increasing quality of service perceived by users.Presenter bio: Member of Center for Eletronics Opto-eletronics and Telecommunications.

- 15:50 Vehicle Navigation in GPS denied Environment using Image Registration
- If I do not know my position on global map then I am lost. To overcome the problem presently there are many localization and positioning schemes like GPS, GALILEO, GLONASS, BEIDOU etc. The availability of the services from any of the scheme is compulsory for navigation. Almost all the new cars have already GPS navigation system installed from the manufacturer. Instead of availability of the GPS device in the automobile we may not benefits from it i.e. in GPS denied environment, tall buildings and tunnels. So we could not totally depend on this system. Inertial Navigation System (INS) is the main source after Global Positioning System (GPS) for vehicle navigation. In real time scenario errors generated by INS, lead us to wrong destination. To achieve the exact planned path accurately it is required that INS must have minimum error propagation. In GPS denied environments, an alternative localization method is needed which either support INS for exact navigation or provides navigation independently. Visual Odometry (VO) is used for vision based localization and vehicle navigation. It constitutes straightforward-cheap method to estimate the object location. A single consumer grade camera can replace a typical expensive suit (encoders, IMU, GPS, etc.). The visual information from successive images is used to estimate the movements of the object by image registration. The requirements for a successful registration are sufficient illumination in the environment, dominance of static scene over moving objects, enough texture to allow apparent motion to be extracted, and sufficient scene overlap between consecutive frames. In the proposed method modified normalized phase correlation has been used. In particular Gram polynomial basis functions are applied to remove the Gibbs error problem. Entropy based tensor approximation has been used to remove outliers for robust image registration. The pixel movement between two consecutive images is calculated and converted to meters along the vehicle direction. The new position of the vehicle is estimated by adding the projected pixel movement in the Latitude and Longitude values of the previous position. A few hundred images are taken during a test drive along with their heading data. The positions estimates provided by the proposed VO technique are compared with the GPS values. In 200 seconds the accuracy of the last traveled point is quite satisfactory. The trajectory made by the proposed method computed and compared with GPS data.

The method deals with object appearance and disappearance and can handle false detections introduced by the frame-based detector.Presenter bio: Darko Juric received his BSc and MSc degree from the Faculty of Electrical Engineering and Computing in Zagreb.

- 16:30 Inter-Vehicle Communication, License Plate Verification, and Distance Estimation for the Construction of Driving Surroundings
- In this paper, we proposed a crowd-sensing idea to construct the driving environment so that the driver could have better understanding of his/her surroundings on the highway. We assume that intelligent vehicles would embed a sensing system which is composed of three basic modules, including inter-vehicle communication, license plate verification, and distance estimation. Through the help of inter-vehicle communication, a vehicle can receive a set of IDs from its nearby vehicles. Those received IDs, including the license plate numbers of those nearby vehicles, can further improve the license plate verification function and verify the front vehicle under an uncontrolled environment. Moreover, we proposed a regression method, which models the relationship between the image coordinate and the geometric distance, in order to estimate vehicle distance in the front. Finally, by fusing the vehicle verification and distance information from nearby vehicles, the system would provide a global view to tell the driver which vehicles are around you and their distances. Comparing with the existing ADAS (advanced driver assistance system), this system would support a wider view of the driving environment, and provide a more comfortable and safer driving experience. To fulfill the sensing system, a license plate verification method with the help of inter-vehicle communication and a regression method for distance estimation are detailed in this paper. Based on the results, our system could verify the license plate with a high accuracy rate and provide robust distance estimation.Presenter bio: Hoang Tran Vu received the Master degree from National Kaohsiung University of Applied Sciences, Taiwan, in 2015.

- 16:50 Regional Risk Estimation for Drivers Cutting Intelligent Graph with Intra Cells Enabling Risk Transfer for Street Players
- As a vehicle proceeds on urban road that includes possible street players such as pedestrian, vehicles, traffic signs, traffic lights, or crosswalks, we can mention about holistic risk caused by dynamic behavior of each items moving along stochastic directions. In the numerous studies, traditional risk estimation methods have been devoted to utilize traffic agents, which have not resulted in effective outcome for a vehicle resided at somewhere among these agents and sometime at its own place. In our scenario, we consider total emerging risks for a driver owing to continuous movements of some of agents on the scene. Specified partitions are envisaged for each agents referring to players at the sight of driver, each of which might have risks as the time goes on. One or multiple agents may occupy in same partition. Therefore, we can mention about potential risks for the subject vehicle. This study has inspired from conventional Graph Cut theory. Graph vertex representing partitions may have transferable risk capacity for the agents in the scene. Vertexes can be imitated to memory cell array that have transferable risk capacities enabling the system to estimate instant risks as traveling in city traffic. As an outcome of this study, the proposed system suggests a driver to take a caution while moving along the street at clutter environment.Presenter bio: I have been working at Firat University, department of Computer Technology.

- This paper studies the problem of vehicle platooning with a particular focus on evaluation of lateral trajectories when one or several vehicle(s) merge(s) from the adjacent lane into the main vehicle platoon under longitudinal control. The merging vehicles should be capable of executing lateral maneuver in different platoon speeds while avoiding high lateral acceleration. For this purpose two adaptive lateral trajectory generation techniques are proposed and compared. Performances of different controllers are tested under adaptive lateral maneuvers when multi-vehicles change lane to join the platoon. The proposed approaches are then tested and verified in our newly developed simulation platform SimPlatoon.Presenter bio: Azim Eskandarian is a Professor of Engineering and Applied Science at The George Washington University (GWU) where he joined in 1993.

The survey yielded useable responses from 1,596 persons over the age of 18. The main results were as follows: • The majority of respondents had not previously heard of connected-vehicle technology; however, most had a positive initial opinion of the technology. • The majority felt that the expected benefits presented in the survey are likely to occur. • Respondents generally expressed a high level of concern regarding the security and performance issues presented in the survey. • The majority of those surveyed stated that safety was the most important aspect of connected vehicles. • Most individuals said that it is important for personal communication devices to integrate with connected vehicles, as well as for such vehicles to have Internet connectivity. • The majority of respondents expressed a desire to have this technology in their vehicle. • Willingness to pay for connected-vehicle technology was very similar across the three countries. The main implications of these results are that the general public in the three countries surveyed feel positive about connected vehicles, have optimistic expectations of the benefits (while still maintaining some concerns), and generally desire connected-vehicle technology when it becomes available.Presenter bio: Brandon Schoettle is a Project Manager in UMTRI’s Human Factors Group.

- 10:40 OWL: Optimized Weighted Localization for Vehicular Ad Hoc Networks
- Vehicular Ad Hoc Networks (VANETs) allows the exchange of messages between neighboring vehicles or roadside units (RSU). The performance of VANET applications is subject to the ability of determining the location of the vehicles at anytime and anywhere within the network, and thus demands real-time, precise position of vehicles. Accordingly, a number of methods and protocols have been proposed to fulfill this requirement, however, the accuracy of the obtained location is not sufficient for VANET safety applications. We propose an enhancement to our previous localization method, weighted localization using distance information (WLD), that uses signal to interference-noise ratio (SINR) obtained from the exchange messages, and distance between the neighboring vehicles to assist vehicles in estimating their positions. Our proposed optimized weighted localization (OWL) uses the heading information shared by the neighboring vehicles in addition to the SINR and distance information. Our proposed method is an extension to centroid localization (CL) with a weight assigned to each of the neighboring vehicles' coordinates, based on SINR values, distance and heading. We implement a simulation program to evaluate the proposed method against CL, WLD and relative span weighted localization (RWL). The results show the proposed method to have better performance and consistently less average location errors in varying densities.

Geographic information system (GIS), which has strong capabilities of storage and management for geographic information, will play a key role in path planning for UGV. Firstly, construct a GIS database aiming at the needs for perceiving the urban traffic environment and storing traffic information related to the perception and decision-making of UGV; secondly, establish a prediction model of travel time based on RBF neural network to predict the travel time of each section, then use the actual travel time achieved by real car experiments to constantly update the predicted travel time; thirdly, a path selection method based on probability is proposed according to people's demand of daily trips; lastly, the GIS database in the simulation will provide several alternative paths, with which the probabilities of arriving on time and arriving at the optimal time can be calculated for each path, help the travelers select their paths in accordance with actual situations. Experiments have shown that the proposed path selection method based on GIS database can provide more efficient paths for UGV driving, guiding UGV to complete the driving tasks successfully.Presenter bio: Xinping Wang received the B.E. from Beijing Institute of Technology (BIT), China, in 2012.

- 11:20 Geospatial Data Aggregation and Reduction in Vehicular Sensing Applications: the Case of Road Surface Monitoring
- Mobile devices present several features which make them attractive as enabling technology for crowdsensing systems. In particular, their spectrum of sensing capabilities, together with consolidated diffusion and ease of use contribute to an increasing adoption in different mobility-based sensing scenarios. On the other hand, the availability of massive volumes of geospatial data provided by large-scale distributed sensing systems prompts the need for innovative approaches to efficient data gathering and processing. Data reduction strategies are often necessary in order to cope with challenges posed by these volumes, for instance when dealing with real-time visualization of query results. In this paper we present a data reduction and aggregation approach for mitigating the impact of data size in a vehicular sensing application aimed at monitoring the roughness of road surfaces. Data collected by smartphones on board of vehicles is progressively thinned at different levels of the proposed architecture through sampling and spatial/temporal aggregation. Preliminary results show that the proposed methodology provides substantial benefits in terms of reduced impact of data while, at the same time, it enables full exploitation of statistical error compensation.Presenter bio: Born in Berne (CH) in 1984.

- 10:20 Understanding the Channel Busy Ratio Metrics for Decentralized Congestion Control in VANETs
- Most of the emerging applications for road safety and traffic management rely on the frequent exchange of awareness messages among vehicles. Unfortunately, the 802.11 protocol poorly behaves under congested scenarios and cannot guarantee the reliability and timeliness demands of massively transmitted broadcast messages, leading to the severe degradation of safety. Recently, there has been a consensus from academia, automotive industries and standardization bodies in adapting transmission parameters (e.g., rate, transmission power) according to the channel load status. Although the objective of controlling channel load can be met with local load measurements only, the participation and fairness principles require the dissemination and sharing of load information among vehicles. In this paper, we aim to shed light on the dynamics of the channel busy ratio (CBR) metrics (locally measured and shared over one/two hops), commonly used in the literature and at the basis of the Decentralized Congestion Control (DCC) standard, under different density and mobility settings.Presenter bio: Riccardo Scopigno achieved his M.Sc. in 1995 and his Ph.D. in Electronics and Telecommunications 10 years later, while working.

- 10:40 Simulation of Region-based Geocast Routing Protocols
- As one of the most important enablers of Intelligent Transportation System (ITS), Inter-Vehicle Communication (IVC) have been a hot research direction in nearly a decade. To improve vehicle safety and cooperative systems, most of ITS applications need efficient and stable Vehicular Ad hoc Networks (VANETs) among vehicles and infrastructures, which can be set up by Geocast routing protocols. Some of these applications require the protocols, known as region-based Geocast routing protocols, supporting to broadcast messages to vehicles within a specific geographic region. Since different protocols are appropriate for different purposes or occasions, it is significant to simulate protocols and evaluate their performances under a variety of scenarios. Therefore, this paper focuses on investigations of simulation environment configurations for some known Geocast routing protocols. According to the investigations, a region based Geocast routing simulator is designed and developed. To demonstrate the effectiveness and the reliability of this simulator, several protocols are simulated and the performances of them are presented.Presenter bio: Tony Larsson, is Professor of Embedded Systems at Halmstad University.

- Vehicular Ad hoc Networks (VANETs) is a technology to support communication among vehicles or between vehicles and infrastructure in order to exchange traffic information and avoid accidents. Many applications in VANETs need to transmit messages to vehicles within a specific geographic region. This behaviour is called Geocast. Several Geocast routing protocols have been proposed for VANETs. In this paper, some important and representative Geocast routing protocols are summarized and theoretically compared. In order to evaluate the performance of these protocols, the evaluation methods are also defined, which include both the Packet Delivery Ratio (PDR) and the Packet Delivery Time (PDT). Additionally, some important and new models, such as the influences of city lights, and the distance between buildings potentially acting as free line of sight obstacles, are proposed to create a more realistic city environment for Geocast routing simulation.Presenter bio: Rui Wang is from Tianjin, China.

- 11:20 Routing Protocol for Complex Three-dimensional Vehicular Ad Hoc Networks
- Due to the existence of three-dimensional (3D) scenarios in realistic Vehicular Ad hoc Network (VANET), such as the viaduct, tunnel and ramp, the distribution of vehicles is 3D. To the best of our knowledge, the issue of designing a routing protocol for 3D VANET has been rarely studied. Our previous work  has provided the routing protocol TDR for the simple 3D scenario which contains two or more parallel roads with different heights. Because the distribution of nodes in the complex 3D scenarios has no rules and no obvious stratification phenomenon, TDR is not suitable for the complex 3D scenarios. Here the complex 3D scenarios are these flyover scenarios with many ramps and irregular arrangement in a large range. Therefore, we propose a novel routing protocol C-TDR for the complex 3D scenarios. In C-TDR we introduce the concept of virtual neighbor and the completion process of neighbor list considering the feature of fluctuant transmission range of nodes in 3D VANET. Finally, we build a simulation scenario containing the simple 3D scene and the complex 3D scene and conduct the simulation for C-TDR. The C-TDR is shown to increase the packet delivery rate and decrease the end-to-end delay and hop count.Presenter bio: Changle Li received the Ph.D. degree in Communication and Information System from Xidian University, China in 2005.

- 12:00 Cellular Aided Vehicular Named Data Networking
- With the recent new paradigm for the future Inter- net named data networking (NDN), contents are searched by names and not by address, and any node storing a content can also act as a source of information. Such a paradigm appears to be of particular interest for vehicular ad hoc networks (VANETs), where vehicles are expected to be equipped with short range wireless communication technologies such as, for instance, WAVE/IEEE 802.11p. In VANETs, devices not only use, but also generate contents; devices are generally not constrained in power or memory, thus easily carrying large amount of information; furthermore, the high mobility continuously creates new opportunities for data exchange. In such scenario, the TCP/IP networking paradigm shows some performance limitations and NDN appears as a way to improve reliability and efficiency of content distribution. However, when the node density is limited, the exclusive use of short range communications might reduce the effectiveness of NDN. Motivated by this consideration, we propose the use of cellular networks to carry the signaling part of NDN, and the exploitation of short range wireless communications for the content distribution. We will show, through simulations performed in an urban scenario with different vehicle densities, that moving the signaling part to the cellular networks significantly improves the performance of NDN compared to the case when only short range communications are used.Presenter bio: Alessandro Bazzi is a research associate of the National Research Council of Italy and he acts as Adjunct Professor at the University of Bologna for courses in the field of wireless communications.

- 10:20 ADCS: An Adaptive Data Collection Scheme in Vehicular Networks using 3G/LTE
- Vehicular Ad-hoc Networks (VANETs) are special kind of Mobile Ad-hoc Networks (MANETs). The distinctive characteristics of the VANETs include high speed of vehicular nodes and high variability in node density. Collecting data from VANETs is important to monitor, control and manage road traffic. However, efficient collection of the needed data is quite challenging due to vehicles mobility and the tremendous amount of events and data generated. In this paper we focus on vehicle data collection using 3G/LTE. In the first step, we compare proactive and reactive data collection schemes using simulation. The results show that proactive gives the lowest delay and bandwidth usage but the most loss ratio. Interested in optimizing the bandwidth usage, an adaptive data collection scheme will be provided. It is based on the proactive scheme while it uses variable periods depending on the vehicle position and travel time to provide accurate traffic and travel time information to the Traffic Management Center~(TMC). Emulation results, using taxi traces in Qatar, shows that our algorithm consumes an acceptable amount of mega bytes (~ 31MB) per month when the basic reporting period is set to 10s.Presenter bio: Fethi Filali is the Head of Technology Development & Applied Research at Qatar Mobility Innovations Center (QMIC).

In the near future, we shall quite likely mention about new generation drivers who wish to get social based data and its manipulation. Hence, we should develop new driver necessity strategies satisfying Internet based requirements for new generation drivers. Here, we propose a system suggesting sub-trip options without ruining driver's primary trip plan. In fact we consider driving efficiency taking pleasure in driving by means of social computing rather exploiting traditional data manipulations such as safe driving, fuel-efficient driving, and obtaining traffic data. For the sake of new generation driver wishes, we develop a model using trip data and feedback information provided by drivers earlier visiting intended attraction place. Then we utilize a social platform associated with central server holding social data such as road safety, weather conditions, and satisfaction rate of attraction place. In this study, we earlier define driver profiles as gourmand, shopaholic, adventurer, art lover, and technophile. Therefore, we propose a system satisfying possible sub-trip expectations of drivers having different profiles. Eventually, we have modeled a new generation inter car sub-route advice platform for pleasant and efficient trip.
- 11:00 Hierarchical and Hash-based Naming Scheme for Vehicular Information Centric Networks
- In this paper, we propose a hierarchical and hash-based naming scheme for Vehicular Information Centric Networks (VICNs). Our proposed naming scheme makes the best use of the features offered by hierarchical as well as hash-based naming schemes. The hierarchical part of the content name contains information about content owner or generator, content type, sub-types, and attributes of the digital content itself that is shared between vehicles. It serves two main purposes: first, it helps in minimizing the routing table by aggregating the names and simplifying the routing decisions. Second, it contains attributes, spatial, temporal and their range information to easily find and resolve the content. The hash part uniquely identifies the digital content required for VICN applications.Presenter bio: Dr. Safdar H.

- In this paper, we provide the specification of a cloud-initiated Point-of-Interest (PoI) application, and illustrate its requirement for a convergence between IPv6 mobility management and Dedicated Short Range Communications (DSRC) geographic services. We propose to extend a flat IPv6 mobility management architecture with a new functional block, namely LIMME (Location \& Infrastructure Mobility Management Entity), composed of three key functions: a Location Manager (LM) acting as location anchor point for cloud-based services, a Geographic Mobility Management (GMM) function acting as location proxy for the LM and handling IPv6 mobility, and an Infrastructure Node selector, which selects a route based on geographical data and local infrastructure node conditions. As a proof-of-concept, we implemented these extensions on the iTETRIS ITS simulation platform and illustrated their benefits in enhanced IPv6 mobility management and traffic offloading.Presenter bio: Panagiotis Matzakos was born in Athens, Greece in 1986.

- 13:30 Technology Evaluations of Personal Mobility Vehicles in Tsukuba-City Mobility Robot Designated Zone
- Many researchers have been seeking ways to solve traffic problems. Also, some countries, especially Japan, will face an unprecedented situation, with fewer children and an aging society. Thus, new eco-friendly and universal mobility are expected. In order to evaluate new mobility and transportation system, it is necessary to perform experiments under real world condition as a pilot study. We performed technology evaluations and demonstration experiments for personal mobility with Tsukuba city, which is a local city in Japan. In this paper, one of the experiments is explained. We proposed a personal mobility sharing system using two kinds of two-wheel and self-balancing vehicles. The proposed experiment is one of the pilot programs, and its result is valuable for evaluating the social receptivity, safety, and efficiency of a mobility sharing system. These experimental data are utilized to construct simulation model on transportation study for the purpose of exploring the capability of these kinds of system as a future transportation.Presenter bio: Naohisa Hashimoto is a senior researcher of smart mobility Research group in National Institute of Advanced Industrial Science and Technology (AIST).

- Personal vehicle transit is focused on as a key technology to solve transit issues in Japan. Some traveling salesmen and deliverymen in urban areas travel using personal vehicles instead of vehicles or motorcycles. However, few families use personal vehicles. This study investigates coupling technologies that will encourage families to purchase personal vehicles. Coupling technologies should offer reliability, operability, and cost balance.

- 14:10 Variability Analysis of In-Car Gesture Interaction
- In this paper we present an analysis of the variability of contactless gestures performed to control secondary functions in a car. In particular, those used to control the music player. We set up a Wizard-of-Oz experiment in a driving simulator where participants performed the gestures they think they would use to control the functions of the music player. The results of the experiment show a high level of variability in the gestures performed by different drivers for the same function. This could lead to driver distraction as well as user acceptance issues if a gesture vocabulary is 'enforced' in order to use these systems. Thus, vehicle manufacturers should provide solutions to overcome these issues, such as gesture customization.Presenter bio: Dr. Joachim G.

- 13:30 Dynamic base station DGPS for Cooperative Vehicle Localization
- Cooperative approaches are becoming of great interest in automotive research. One of the most important ITS applications is cooperative localization. In this paper, the concept of a dynamic base station DGPS (DDGPS) and its application in the vehicular cooperative localization is introduced and discussed. The DDGPS is a decentralized cooperative method which aims to improve the GPS positioning by estimating and compensating the common error in GPS pseudorange measurements. It can be seen as an extension of DGPS where the base stations are not necessarily static with an exact known position. In the DDGPS method, the pseudorange corrections are estimated, based on the receiver's belief on its positioning and its uncertainty, and then broadcasted to other GPS receivers. A new method for fusing all the received corrections from different sources is proposed and the data dependency problem is also discussed.Presenter bio: Mohsen Rohani was born in Iran in 1985.

- We present an adaptive motion model for tracking the movement of smartphone user by using the motion sensors (accelerometer, gyroscope and magnetometer) embedded in the smartphone. A particle filter based estimator is used to seamlessly fuse the adaptive motion model with a WiFi based indoor localization system. The system applies Gaussian process regression to train the collected WiFi received signal strength (RSS) dataset, and particle filter for the estimation of the smartphone user's location and movement. Simulations were conducted in MATLAB to provide more insights of the proposed approach. The experiments carried out with an iOS device in typical library environment illustrate that our system is an accurate, real-time, highly integrated system.Presenter bio: Xiang He PhD Deep Learning Research Engineer at ReTech Labs Graduated from Electrical and Computer Engineering Department at Oakland University
- 14:10 A Multi-Weights Map Matching Algorithm used in GPS System for Vehicle Navigation Application
- Map Matching (MM) is an important part of Intelligent Transportation System (ITS). GPS fusing electronic map model is frequently used for vehicle navigation application. While most of the existing solutions fail to provide trustworthy trajectory when the situation is ambiguous (U-turn, road intersections … ). Azimuth Angle of GPS point (AZP) started to be utilized as a new feature in Map Matching. This method can enhance the matching accuracy of GPS points around the intersections. This paper proposes an improved Map Matching algorithm based on Multi-Weights. Through integrating these Multi-Weights to search the optimal road among many candidates for GPS point. The navigation solution was tested in urban area by mounting the navigation system on a land vehicle. The assessment of the Multi-Weights algorithm is based on comparing the trajectory after Map Matching with the GPS-Only trajectory and the reference trajectory, obtained with higher grade sensors, through which the proposed algorithm provides a significant enhancement in the positional accuracy.
- 14:30 Vehicle Self-localization in Urban Canyon Using 3D Map based GPS Positioning and Vehicle Sensors
- Precise and robust vehicle localization in the urban canyon is a new challenge arising in the autonomous driving and driver assistance systems. Sensor integration is proposed to realize this target in this paper. Global Positioning System (GPS) has been proven itself reliability for accurate vehicle self-localization in the open sky scenario. However, it suffers from the effect of multipath and Non-Line-Of-Sight (NLOS) propagation in urban canyon. The paper proposes to estimate vehicle position by using 3-dimensional (3D) map and ray-tracing method in order to overcome the problems in urban canyon. The proposed positioning method distributes numbers of positioning candidates around of reference positioning, and then the weighting of the position candidates are evaluated based on the similarity between the simulated pseudorange and the observed pseudorange. In this way, the additional 3D map information is used to reduce the effect of multipath and NLOS. Moreover, the information from vehicle sensors, including motion sensor and rotation sensor, are integrated with the GPS positioning result in a Kalman filter framework. The integration not only smooths the trajectory of vehicle, but also reduces the positioning error. The experimental results demonstrate the accuracy of our proposed method and its feasibility for autonomous driving.
- 14:50 Vehicular Cooperative Map Matching
- In this paper a novel Vehicular cooperative map matching method is presented. This map matching method uses the V2V communication in a VANET to exchange GPS information between vehicles. Then vehicles can apply the road constraints of other vehicles in their own map matching process and acquire a significant improvement in their positioning. The dependency of GPS measurements between different vehicles, which can lead to an over converged positioning result has been considered and circumvented in our method. The performance of the proposed algorithm has been verified with simulations in several realistic scenarios.Presenter bio: Mohsen Rohani was born in Iran in 1985.

- 13:30 Distributing Blackbox Data to Multiple Vehicles in a Secure and Privacy-preserving Manner
- In addition to information such as the track of wheels, vehicle blackbox data (like a blackbox in an aeroplane) provides another major source of information for the study of the cause of car accidents. However, according to a study, 5\% of blackboxes were destroyed in traffic accidents and about 35\% data inside a blackbox could not be retrieved. With the setup of vehicular ad hoc network (VANET), it is motivated to store the blackbox data in a distributed manner in the road-side units of such a network. This scheme works well provided that there are enough road-side units installed. But this assumption is not valid in rural areas and also may impose a large overhead to road-side units. In this paper, we propose a distributed scheme that allows vehicles to periodically broadcast blackbox data to nodes nearby (other vehicles) as extra backup. And the trusted authority can reveal those data from recipients. The proposed scheme will ensure the integrity and confidentiality of messages as well as the privacy of drivers. We show that our scheme is secure and the performance is reasonable through simulation.Presenter bio: C.Y.

- 13:50 Providing Internet to Trains using MIMO in LTE Networks
- Providing broadband passenger internet on board trains with continuous connectivity at high speeds and over large rural distances is a challenging issue. One solution to the problem is to use an onboard WiFi network connected to multiple 3G and 4G networks deployed outside the train and aggregate their combined capacity at the IP protocol level. In order to be able to provide the capacity and the data rates that tomorrow's travelers are expecting, the future 4G standard (LTE - Advance) uses a combination of high order MIMO and carrier aggregation. In this study we use the Swedish company Icomera's passenger internet system for our investigation. The system provides aggregation of multiple carrier and handover on an IP level. For about 10 years the system has in Sweden primarily been using multiple 3G communication links. However, here we present analysis and onboard measurements of the MIMO channel to fast moving train in a live LTE 900 network. The results indicate that MIMO works surprisingly well and it is discussed that by combining 8x8 MIMO with carrier aggregation in future releases of 4G, it may be possible to bring gigabit internet connections to trains.Presenter bio: Claes Beckman is a visiting antenna systems engineering professor and the founding director of the research center wireless@kth.

- 14:10 Optimal Deployment of Road Side Units in Urban Environments
- In this paper, we address the problem of Road Side Unit (RSU) deployment in urban environments. One of the main goals in designing a Vehicle-to-Infrastructure (V2I) network is to find optimal locations for deployment of all the RSUs. The objective in our case is to cover all the road parts that have the highest car density using a limited number of wireless access points (the number of available RSUs is an input parameter in our formulation). Such design improves data delivery to moving vehicles by maximizing the network coverage and enabling higher data rates. To deal with the RSU deployment problem we propose a methodology which starts by characterizing the mobility of cars using real data traffic. In this step the parts of the road that have the highest average car density over a long period of time are identified. This data is used as input for the formulated nonlinear integer programming problem. The solution to this problem determines the optimal location for RSUs deployment given a fixed budget for networking equipment. Numerical results show that our formulation provides a more optimal solution for RSUs deployment when compared with other deployment strategies proposed in the literature.Presenter bio: Dr. Piotr Szczechowiak is a Senior Research Scientist at Zylia Sp. z o. o.

- 14:30 A Survey on Intersection-Based Routing Protocols in City Scenario of VANETs
- As is known, the intersection-based geographic routing protocol is a promising solution to the information dissemination in realistic city environments. Also, there exists a series of special issues for VANETs urban area. Aiming to tackle these issues, many such routing protocols have been proposed in academia. In this paper, we present four important issues for city scenarios which not only strongly affect the performance of routing protocols, but also will be key factors to prompt us to redesign more suitable routing protocols. Those issues include intermittent connectivity, traffic light at intersections, three-dimensional and traffic accident city scenarios. Then we give a survey on recent intersection-based geographic routing protocols and explore how those issues impact the performance of these protocols. In order to better reflect the influence of these issues, we perform a simulation-based analysis. We evaluate the performance of the existing routing protocols including GPCR, GyTAR, STAR, and TDR in city scenarios with above issues. Simulation results prove that these scenarios affect the performance of routing protocol significantly. Finally, we put forward guidelines which are conductive for designing VANETs routing protocols.Presenter bio: Changle Li received the Ph.D. degree in Communication and Information System from Xidian University, China in 2005.

- 14:50 A 3D Web-based Visualization Tool for VANET Simulations
- VANET Simulation schemes require a combination of mobility and wireless network simulation packages, coupled with custom scripts, visualization tools and various scenarios. The results of simulation studies need to be supported by special tools or scripts to analyze or visualize them easily. Some additional difficulties arise at sharing the results, visually comparing simulation runs across different platforms and showcasing the findings of a research to a larger audience. As a solution, we have developed a 3D Web-based Visualization Tool for VANET Simulations (WGL-VANET), which takes advantage of HTML5 and WebGL technologies to create a cross platform, easy-to-use and flexible visualization tool for VANET simulations. WGL-VANET reads simulation data from a JSON document and supports a variety of visual features, and displays the simulation run on a WebGL canvas inside a web-browser.
- 15:10 Making Inter-flow Network Coding Possible for Unicast Routing in VANETs
- Designing an efficient unicast routing protocol for vehicular ad hoc networks has been a challenging issue due to the vehicle movement, limited wireless resources and lossy feature of wireless channel. We propose a protocol which utilizes inter-flow network coding to route data messages. The proposed protocol uses common backbone vehicles for different traffic flows. A reliability connected backbone is selected by considering vehicle movement dynamics and link quality between vehicles. By using inter-flow network coding at the backbone vehicles, the protocol can reduce the number of generated packets by 25% in most cases as compared to conventional routing approach. As a result, the proposed protocol can provide high packet delivery ratio, low overhead and low delay. We show the effectiveness of the protocol using theoretical analysis and computer simulations.Presenter bio: received his M.E. degree from Beijing Institute of Technology, Beijing, China, in 2006, and PhD degree from the University of Electro-Communications, Tokyo, Japan, in 2010.

- 13:30 Efficient engineering of safety-critical, software-intensive systems
- The transportation ecosystem is currently in a transition phase from combustion to electrified, from isolated to connected, and from hands-on to automated. During this transition, new disruptive technologies replace existing technologies and then quickly become obsolete themselves. As drivers provide less input into driving decisions, safety and efficiency become even more critical and difficult to achieve: driving decisions increasingly rely on software, while automotive engineering traditionally relies on mechanical solutions. In the rush to deploy solutions with the latest technology the quality of the software can suffer. The objective of this work is to suggest changes needed in current automotive software engineering to meet the levels of quality demanded by autonomous, connected vehicles. One of the biggest changes is that vehicle and infrastructure technology needs to be developed in context. Strategic decisions concerning which technologies to integrate and the development processes to use require an understanding of the emerging markets. The development method outlined here provides an organization with guidance on using ecosystem roadmaps and a high integrity software development process to accommodate emerging technologies and ever shorter product cycles. In part guidance is given by fitting those technologies into existing, validated architectures and in part by specifying V&V techniques that detect defects early. The result is an environment in which safety-critical products are developed more effectively and efficiently.Presenter bio: Dr. Joachim G.

- 13:50 An Approach to Designing an Autonomic Network of Traffic Managers
- Critical improvements are needed to handle a huge increase in the volume of vehicles that use the current urban transportation network. The surface transportation must become safer and smarter. Current advances in wireless communication technology can be brought in to achieve connectivity in surface traffic and based on it services can be provided for drivers of vehicles to avoid collision and congestion, while improving safety and security on one hand, and facilitating navigation and routing on the other. To achieve this kind of vehicle-to-vehicle (V2V) connectivity, interoperability between wireless devices is necessary. However, managing the communication complexity in a huge traffic network is hard, whether or not the vehicles are driven by humans. In the former case the drivers may be loaded with information from external sources and the task of reasoning with the information, which are often conflicting, will effectively distract them from driving. In the later case, the embedded system in the vehicle must also include policy databases and a reasoning engine. Putting such a demand on the embedded system only increases the complexity of the system, because there is no guarantee that correct decisions can be made in real-time. In this paper the goal is to provide the vehicle a minimum set of simple tasks, and allow it to be largely guided by the smartness of the infrastructure. This vehicle-to-infrastructure (V2I) connectivity is emphasized as the basic building block to ultimately (perhaps indirectly) achieve V2V. Assuming that every vehicle has a built-in set of embedded systems which perform intelligent actions, such as location sensing, Anti-lock Braking System, and Lane Change Warning System, it is shown that a collision-free coordinated motion of vehicles can be achieved by designing a network of autonomic Traffic Managers (TM), where each TM manages vehicles using its own resources such as real-time controllers, arbiters, and other external actuators. Being autonomic a TM will have the ability to reconfigure the system owned by it, protect itself from unauthorized attacks and repair itself in order to minimize its downtime.Presenter bio: Dr. Vangalur (Vasu) Alagar is Professor Emeritus at Concordia University, Montreal, Canada.

It handles real traffic situations in urban environment. The validation is performed in order to determine the extent of conformity of the model i.e. simulator with the real traffic stream in urban environment. The process itself is based on qualitative and quantitative comparative analyzes of the model parameters and experimentally obtained traffic stream parameters.

- 14:30 Safety Management on Hazardous Material Transportation
- The safety management of hazardous material transportation is important for the people's life, the environment and the economy. Currently, trajectory monitoring systems are set up to manage the hazard material transportation in China. However, the coordination among different departments of government on accident prevention, handling and investigation is still in low efficiency due to lack of means. This paper proposes a centralized monitoring and safety management system for all the users, including the transportation enterprise and every related government departments and service organizations. Based on the Internet-of-Things technologies, this system uses various methods to monitor the status of the person, the vehicle, the goods and the roads, so as to detect every sign before an accident try to avoid it. To elevate the efficiency of accident handling, this system coordinates every relevant department of the government to be alerted at the first time and react immediately according to the prepared emergency plan with full information of the site. This system also collects sufficient information for accident investigation. This system can improve the efficiency on accident prevention, handling and investigation.Presenter bio: Wenjie Chen is an associate professor at Software School of East China Normal University (ECNU).

- 14:50 Infrastructure based sensor fusion for enhancing the positioning accuracy to vehicles for enabling safety critical ITS applications
- Intelligent cooperative transportation systems (ITS), dedicated short range communication (DSRC), vehicle to vehicle /infrastructure communication (V2X) technologies support applications for improving traffic information and road efficiency. Using this technology for increasing safety such as real-time crash mitigation, an accurate position matching of vehicles to driving lanes of a given topological map is required. Today's vehicles or mobile devices use satellite based positioning systems and data fusion of additional sensors, which is still not a guarantee for a reliable position acquisition, satisfying the requirements for safety applications. This paper presents positioning calculation procedures, based on road infrastructure sensors, for driving vehicles and moving pedestrians. An ITS infrastructure equipment, mounted on the road side, is stationary and therefore knows exactly its GPS position. Such an ITS roadside station is able to track moving ITS stations (vehicles, bicycles, pedestrians, etc.) by reception of their radio signals and using additional sensing technologies like angle of signal arrival, radar, video, etc. The combination of infrastructure based sensing technology and the exact knowledge of the surrounding map, allows an ITS roadside station to execute a correlation algorithm for reliable estimation of the position of moving ITS-stations. The combination of infrastructure based positioning computation and vehicle own positioning information will lead to a high accurate and reliable position computation and enable pedestrians or vehicles to execute critical safety applications (e.g. execution of lane based maneuvers in intersections, wrong way driving, etc.)Presenter bio: Fritz Kasslatter has received his Diploma degree in communication engineering from the Technical University in Vienna in 1988.

- Due to population ageing, the number of people that depend on mobility aids, such as walking frames, mobility scooters, or wheel chairs, will increase steadily over the next decades. In order to support the physical impaired outside traffic participants, barrier-free navigation and trip planning solutions have been developed. In this work, we go beyond these approaches and investigate potential benefits arising from the integration of mobility aids in vehicle-to-x communication.

- 16:30 Understanding Traffic: Towards a Smart Traffic Control Architecture
- We address the problem of traffic jams at connected intersections by proposing a simplified model for a network of four connected intersections, each has four incoming and four outgoing single lane roads. The proposed model, on the other hand, is flexible and can fit to any real case study with different intersections structures and topologies. We conduct discrete-event simulation in order to sturdy the effect of traffic arrival rate and traffic directions on average processing time for cars. We show that delay exhibits exponential behavior with regards to poison arrival model, which is expected, however, it is essential to identify the break point for traffic delay based on the arrival rate, which can be used for further consideration of methods to reduce this delay.Presenter bio: Amjad Gawanmeh is an assistant professor at the Department of Electrical and Computer Engineering at Khalifa University, UAE since 2010.

- 16:10 A street safety inventory aid using an automated smartphone-cloud application
- Potholes, debris, sunken manhole covers and others are common street safety hazards drivers experience daily as they "bump" into them unexpectedly while driving. The repair and maintenance process by municipals is an ongoing effort that requires periodic streets inventory to guarantees safety. Unless someone reports the location of a street problem, such process cannot take place. This paper presents a simple, yet an effective technique to aid in reporting such street hazards automatically using a smartphone application. The smartphone's accelerometer is used to detect bumps during driving and report the data and location to cloud service. The cloud application utilizes an artificial neural network that is trained to differentiate between a "shock" resulting from normal driving maneuvers from those possibly resulting from road problem. It also analyzes the location and based on the frequency of reporting a certain "shock" data from the same geographical location it reports a street hazard location. The city's municipal can then take the suitable actions for inspection and repairs. Promising results were obtained by using a preliminary test implementation indicating the effectiveness of the proposed technique.
- 16:30 Intelligent driving lane with RF-ID for vehicle navigation system
- In our residential area, northern part of Japan, we sometime meet heavy snow fall and are put into low visible condition due to the snowstorm. Unfortunately, some drivers go out from their driving lane. In order to prevent, such traffic accidents with low visible condition, we developed a vehicle navigation system with UHF RF-ID system. There are several studies related on lane departure and vehicle positioning. Some of them uses GPS, DSRC, and other technique, and are some application of triangular surveying. Our navigation system finds vehicle position using information written on RF-ID tag buried under the road surface. From the view point of lane support system, buried RF-ID tags has capability to make the driving lane intelligent with driving support information. We will show our navigation system on this viewpoint.
- 16:50 Automatic estimation of road inclinations by fusing GPS readings with OSM and ASTER GDEM2 data
- This work presents a method of estimating the slope of road networks that are ground-modeled by OSM originally. The aim is to get 3-D road vectors including their 2-D location and inclination, that is an important parameter to ensure more reliable route planning. This is done from GPS data that are collected by a vehicle traveling on an existing OSM road network whose a DEM, like SRTM or ASTER data, provides a modeling of the terrain surface. GPS, OSM and DEM data are modeled as measurement equations in order to account for their errors in an UKF that fuses them in a centralized scheme. Here, the key step is to match GPS/OSM/DEM measurements successively by computing statistical Mahalanobis distances. The experimental framework show some results of road inclinations estimation and the significant contribution of a DEM as baseline.Presenter bio: Christophe Boucher received the PhD degree in computer science engineering from the Université du Littoral Côte d'Opale (ULCO), Calais, France, in 2000.

- In this paper we present a novel algorithm which minimizes peak-to-average power ratio (PAPR) of the orthogonal frequency division multiplexing (OFDM) signal used in IEEE 802.11p like transmission. The proposed algorithm is an extension of the widely known selected mapping (SLM) algorithm.

Simulation results prove the usefulness of the proposed algorithm.
- 16:10 The Impact of Jamming on Threshold-Based Agreement in VANET
- In Intelligent Transportation Systems (ITS), Dedicated Short Range Communication (DSRC) enables communication among vehicles (V2V) and vehicles to infrastructure (V2I). ITS safety applications are designed to increase road safety and to reduce accidents. The reliability of DSRC-based ITS safety applications is essential. Thus, improving resiliency against faults, and enhancing reliability, are primary goals. Research has shown that threshold-based agreement methods effectively reduce the impact of value faults through validating events, by receiving the Basic Safety Message (BSM) from multiple sources. Whereas previous work considered value faults, e.g., injection, data fabrication and sensor manipulation, it does not address the impact of omission faults and jamming. This paper investigates the impact of jamming on threshold-based agreement in Vehicular Ad Hoc Networks (VANET). It is shown that jamming drastically reduces the correctness of the voted upon decision. We consider the Emergency Electronic Brake Lights (EEBL) safety application, and demonstrate how jammer position and power affect the correctness of the decision. Furthermore we show how the number of vehicles impacts the correctness of decisions in the presence of jamming. Finally a new adaptive threshold algorithm is introduced that improves the resilience against jamming attacks compared to algorithms presented in previous research.
- 16:30 An Information-Centric Approach for Data Dissemination in Vehicular Networks

However, some design principles of ICN must be implemented and extended in order to realize efficient data dissemination in vehicular networks. This paper proposes an information-centric data dissemination approach in vehicular networks. An architecture for organizing and disseminating information in a vehicle has been suggested. Clusters of common interests are proposed, which are established dynamically by vehicles based on the information in which the they are interested. Within each cluster, information are disseminated to the vehicles in a way decided by the features of the information. To show the feasibility of our approach, we have implemented the approach in the simulation environment.Presenter bio: Prof. Dr. Ing.

- 16:50 Mobility Pattern based Misbehavior Detection in Vehicular Adhoc Networks to Enhance Safety
- Vehicular Ad-hoc Networks (VANETs) can make roads safer, cleaner, and smarter. It can offer a wide range of services, which can be safety and non-safety related. False or bogus information is a real threat in VANET's safety applications, security and privacy. Vehicles or drivers may react to false information and cause serious problems. In VANETs Drivers' behavioral tendencies can be reflected in the mobility patterns of the vehicles. Monitoring mobility patterns of the vehicles within their transmission range helps them in earlier detection of the correctness of the received message. Detection of the false message is not enough to enhance the security and safety. The misbehaving vehicles must be also detected and penalized, so they will not misbehave in the future. Existing misbehavior detection schemes have not adequately addressed this issue in the highway. In this paper we present a misbehavior detection scheme (MDS) and framework based on the mobility patterns analysis of the vehicles in the vicinity of concerned vehicles. The proposed MDS is a hybrid mechanism of both Data-Centric and Entity-Centric to cover wide range of misbehaviors. Simulation results demonstrate the potential of the proposed MDS and framework especially in highway safety applications.Presenter bio: Dr. Mohammad Abdur Razzaque (raz) is Senior Lecturer in the Faculty of Computing, UTM, Malaysia.

- 15:50 A Novel Formulation for the Distributed Solution of Load Balancing Problems in Mobility On-Demand Systems
- In this paper, we propose a distributed solution to the load balancing problem in Mobility On-Demand (MOD)systems. First, we present a novel optimization framework for the load balancing problem, then we propose the Distributed Load Balancing (DLB) algorithm, which aims to keep the system balanced and, at the same time, to maximize the number of accepted customers' requests. The DLB algorithm is iterative, and each iteration consists of two phases: in the first phase a feasible assignment to the customers' requests is defined, while in the second phase the assignment is evaluated (and, as a consequence, confirmed or rejected) in order to maintain the system balanced. The performance of the proposed strategy is assessed through an extensive simulation campaign. We validate the performance of the DLB in several operational conditions, by varying the number and locations both of the customers and of the vehicles, also considering different communication topologies among the pick-up and drop-off stations. Finally, a comparison of the performance of DLB with an optimal solver is provided.Presenter bio: Francesco Acquaviva was born in Bari, Italy, in 1985. He received the B.Sc. and M.Sc.

- 16:30 Ontology layering in an early warning sensor (EWS) bicycle accident prevention system
- Every domain has a core ontology, with conceptualization specifications, which defines individuals, class attributes and relations. These abstract relations between classes and sub-classes, governed by events and observations are aligned to specific restrictions, rules and functions, which have structural similarities. Similarly, a descriptive ontology structure exists for sensor devices, which represent concepts unique to sensors. We investigate how sensor devices from multiple domains perform as an early warning collision avoidance system. Sensor characteristics define sensor behavior; this awareness prescribes typical sensor activity related to a particular domain. Primary sensor event processes, associated with event observations, function as a result of trigger or stimuli activities. Matching and correlating sensor event data integration, challenge the collection and analysis of streamed sensor data from various sensor-typical domains. As a consequence, individual sensor ontologies prescribe class relations with specific relevance to sensor ontology domains and how sensor characteristics are portrayed in the intended semantics of the descriptive ontology. Our mock-up Early Warning Sensor (EWS) system, investigates methods to identify, localize, and track users movement in a wireless signal area. The EWS system identifies and correlates different wireless sensor devices, unique to specific sensor ontology, which interact with other devices in a wireless sensor network. As a result device localization estimations, which are required for integrated multisensory data is produced. Approaches in our EWS system may apply to localization techniques in environmental and military positioning, where device and user positions need to be localized with more exactness. Hence, core processes in our approach extend to other domains where uncertain event instances may influence mobile localization prediction. Our spatiotemporal sensor event identification model presents layered event occurrence similarity. Similar sensor event data are obtained during the initial ontology layering processes, and filtered data are temporally layered to a new data set, which includes specific annotated sensor data. This layered new dataset presents sufficient data for localization, based on radio signal strength indicators (RSSI), required for early warning detectionPresenter bio: From a diverse social science background to a Masters MCIS in Digital Forensics at AUT, I am in the last months of my PhD. research at the University of Adelaide.

- 10:20 Vehicle Navigation in GPS denied environments using Image Registration
- Due to the more accuracy and robustness of vision based sensors, the magnetic and optical sensors are ignored in many applications, like in quality control, optical measurement and biomedical applications. Vision based navigation is an open issue nowadays which is generally carried out by image registration technique. The requirements for a successful registration are adequate illumination in the environment, dominance of static scene over moving objects, enough texture to allow apparent motion to be extracted, and sufficient scene overlap between consecutive frames. In the proposed method modified normalized phase correlation has been used. The distinction between changed and unchanged surfaces is based on an identification of corresponding features. In particular Gram polynomial basis functions are applied to remove the Gibbs error problem. Entropy based tensor approximation has been used to remove outliers for robust image registration. The pixel movement between two consecutive images is calculated and converted to meters along the vehicle direction. The new position of the vehicle is estimated by adding the projected pixel movement in the Latitude and Longitude values of the previous position. Velocity of the car could also be found by the method. A few hundred images are taken during a test drive along with their heading data. The positions estimates provided by the proposed technique are compared with the GPS values. In 200 seconds the accuracy of the last traveled point is quite satisfactory. The trajectory made by the proposed method computed and compared with GPS data.

- 10:20 Automatic Traffic Sign Recognition based on Saliency-enhanced features and SVMs from Incrementally Built Dataset
- This paper proposes an automatic traffic sign recognition method based on saliency-enhanced feature and SVMs. As when human observe a traffic sign, a two-stage procedure is performed by first locating the region of sign according to its unique shape and color, and second paying attention to content inside the sign. The proposed saliency feature extraction attempts to resemble these two processing stages. We model the first stage via extracting salient regions of signs from detected bounding boxes contributed by sign detector. Salient region extraction is formed as an energy propagation process on local structured graph. The second stage is modeled by exploiting a non-linear color mapping under the guidance of the output of the first stage. As results, salient signature inside a sign is popped up and can be directly used by subsequent SVMs for classification. The proposed method is validated on Chinese traffic sign dataset that is incrementally built.Presenter bio: Keren Fu is a Ph.D. candidate with the signal processing group at Department of Signals and Systems in Chalmers University of Technology, Sweden.

- 10:40 Probabilistic Risk Assessment using Major Features of Rural Road Curves via Rear and Front Car Cameras
- Rural and secondary roads inherently exhibit road curves and turns. This study aims to predict the risk associated with rural road curves exploiting major curve features such as curvature, slope type, and direction. The images acquired by rear and front cameras are utilized to capture the underlined features. Slope type is obtained by two-view images while direction and curvature are estimated by single-view front camera. Our approach is based on geometrical derivations using visual clues such as vanishing points and curb borders. Consequently, the impact of major features on the risk has been assessed using the Bayesian belief theory and network. The proposed model is expected to be an advanced driver assistant system for long distance drivers, which tackles with prominent risk components associated with road curves. In turn, this type of advanced driver assistance systems would become a critical part of autonomous vehicles.Presenter bio: I have been working at Firat University, department of Computer Technology.

- 11:00 Implementation of a Multivariable Modular Structure for Fuzzy Taxi Scheduling System (FTSS)
- Taxi scheduling problem represent the heart of management problems for most Taxi companies. This is due to the fact that information in such environment is dynamic in nature with a high degree of uncertainty. Fuzzy logic can be utilized to deal with such uncertainty in the information. Genetic algorithm can be utilized for optimization of solution. This paper describes the implementation of a hybridized intelligent algorithm to reach a decision under uncertainty and to tune the possible solution using genetic algorithm. This hybridization is one type of Genetic Fuzzy system termed the Genetic Fuzzimetric Technique (GFT). GFT was used with AHP technique to develop a prototype system to illustrate the proposed solution to the taxi scheduling problem termed as "Fuzzy Taxi scheduling System" (FTSS). The developed prototype can also act as an educational tool towards illustrating the mechanism of building modular multivariable fuzzy system. Using FTSS, five criteria were chosen as inputs and one needed output which is the score of specific driver/taxi. An example of 4 Taxis/Drivers with different characteristic values was executed on FTSS to achieve the final optimized Taxi choice.
- 11:20 Enhanced Work Zone Safety Through Cooperative Autonomous Vehicle Systems
- Despite improvements in work zone safety, injuries and fatalities remain a significant problem for work zone personnel. Crew and vehicles are often protected with the use of a vehicle located at the rear of the work zone, which is fitted with a mechanism to attenuate the impact energy of a vehicle. This vehicle, called an impact attenuation, or crash cushion, vehicle, is designed and placed to be struck by any errant vehicles; however, this vehicle is an active part of the work crew and is often manned by a member of the work crew, and this person can still be injured or killed when the vehicle is struck. This paper will present recent work by SwRI in conjunction with the Texas Department of Transportation (TxDOT) to replace this manned vehicle with a fully-autonomous vehicle, capable of communicating with other vehicles in the work crew, traffic management systems, and, using visual recognition techniques, follow other vehicles in the crew or even respond to arm gestures by a member of the work crew.Presenter bio: PAUL A.

- 10:20 Energy-Efficient Design for TDBC-Based Two-Way Relay Network with Weighted Fairness
- In two-way relay network (TWRN), both end nodes may have different quality-of-service (QoS) requirements accord- ing to their priority, traffic demand, and/or their downlink and uplink split ratio. This paper proposes an easy and energy- efficient weighted fairness solution that can be implemented at the relay node to control the uplink and downlink traffic according to the dynamic traffic changes. An energy efficient design is proposed for two-way relaying (TWR) with time division broadcast (TDBC) protocol that minimizes the allocated power to the two transceiver end nodes and to the relay node under a weighted quality-of-service (QoS) bidirectional data rates. This design utilizes the signal combining process at the relay node in TDBC, also known as relay power allocation (RPA), to provide a new simpler way to ensure the weighted rates without increasing the complexity to control different power allocation of the three nodes. Adaptive calculation of the relay power allocation factor, , is adopted for combining the two received signals to satisfy the QoS requirements with (α) weighting factor. Simulation results shows an improvement in efficiency in terms of the average allocated power and a perfect users fairness compared with tradition Variable-gain relay power allocation (VG-RPA) and with scenarios where a predetermined fixed value of is used.Presenter bio: Basem M.

- 10:40 An Intelligent Clustering Algorithm for VANETs
- Vehicular Ad-Hoc Networks (VANETs) is an emerging technology which is being used in wide areas of applications especially to provide safety and comfort to the users sitting in the vehicles. Vehicles in VANETs act as an intelligent machines for taking adaptive decisions for information dissemination from source to destinations. Vehicles can send warning messages to drivers sitting in the other vehicles about the varying road conditions to increase safety on the roads. But due to high mobility and varying traffic conditions, the delivery of messages to their final destination is a challenging task in VANETs. Clustering is one of the most effective ways of managing and stabilizing such networks. In this paper, a learning automata based clustering algorithm for VANETs is proposed. The concept of number of links and vehicular mobility is used for cluster formation and cluster head selection. During cluster formation, nodes with relatively higher degree of connectivity initially form a backbone which is designated as leader. The leader then participates in cluster-head election and efficient cluster reorganization using aggregate degree of connectivity of vehicles is proposed. Simulation results show that the proposed algorithm has comparable cluster stability in urban scenarios.Presenter bio: Joel Rodrigues [S'01, M'06, SM'06] is a professor and senior researcher at the National institute of Telecommunications (Inatel), Brazil and senior researcher at the Instituto de Telecomunicações, Portugal.

- 11:00 Optimizing Lifetime of Homogeneous Wireless Sensor Networks for Vehicular Monitoring
- Wireless Sensor Networks have several applications such as medical monitoring, automotive safety, and many more. Sensor networks, however, have several limitations, such as vulnerability, short transmission range, small memory, and limited battery life. Several algorithms were proposed to address network lifetime problem in wireless sensor networks. Geographic distribution and density of nodes dramatically affect the choice of protocol, nodes life, and the suitability of the method. Sensor networks are effectively used for vehicular monitoring on highways and hence form a linear topology. Therefore, existing clustering methods and routing protocols are not effective when applied on a network of linear topology. In this paper, we introduce a new method to enhance the lifetime and performance of a homogenous wireless sensor network with linear topology that is dedicated for vehicular monitoring. The experimental results show the effectiveness of the method by enhancing the lifetime of the wireless sensor network compared to direct transmission and clustering methods.Presenter bio: Amjad Gawanmeh is an assistant professor at the Department of Electrical and Computer Engineering at Khalifa University, UAE since 2010.

- 11:20 Fairness-Oriented Channel-Capacity Distribution in Wireless Multi-Hop Networks
- Wireless Multi-hop Networks (MUNETs) are emerged as a key technology for network infrastructures. Thought the several advantages of multi-hop networking, the shared medium access represents a major issue for resource distribution in MUNETs. Therefore, the network topology forms an essential point for determining resource distribution in such networks. Although the importance of network topology for resource distribution is well known, none of known studies analyzed the related effects deeply, i.e., without a comprehensive concept. In that respect, this paper presents the Fairness-Oriented Capacity Distribution (FOCD) concept for analyzing and providing capacity distribution in relation with the network topology (neighborhood graph). For purpose of simplicity, this paper considers only the time-shared medium access based MUNETs, such as MANETs and VANETs. This work determines the major conditions for channel capacity utilization and defines factors for evaluating the capacity distribution. Accordingly, two main algorithms are introduced and evaluated. The analytical (numerical) results of selected examples show that the topology of such networks totally affects the way the channel capacity can be distributed/assigned on the network nodes. Consequently, the analytical results confirm that the maximized distribution of the channel capacity does not necessarily means distributing the whole capacity on the neighboring nodes, but only the part that enables having (stable) nodes.Presenter bio: Robil Daher is currently an Assoc.

- 11:40 Fairness aware Chunk-Based Resource Allocation in Multi-Cell OFDMA Networks
- Resource allocation in multi-cellular OFDMA systems is highly considered nowadays to either maximize system throughput or minimize transmitted power. Although resource allocation per sub-carrier is optimum in terms of system throughput, resource allocation per chunk instead is highly considered to simplify allocation algorithms and minimize required signalling. In this paper, we propose a fairness aware chunk-based resource allocation algorithm for the downlink transmission of multicellular OFDMA system with fractional frequency reuse (FFR) adoption. Simulation results reveal that our proposed algorithm performance exceeds two reference algorithms in literature in terms of average system spectral efficiency (SE), fairness and cell-edge users rates.Presenter bio: Mahmoud M.

- Vehicular ad hoc networks (VANETs) support safety applications to prevent car accidents. Beacons are periodically broadcasted for various safety applications but very sensitive to collision and delay. In this paper, we propose a new transmission scheme, called Bi-Beacon, which transmits two levels of power to reduce collision and maintain maximum transmission range. High collision problem still remains in high vehicle density condition and contention window (CW) control with Bi-Beacon reduces collision but results in larger delay time. We propose a new beacon update scheme which reduces delay time in high density condition.Presenter bio: Heecheol Song (S' 05) received the B.S. and M.S. degree in electrical engineering from KAIST, Daejeon, South Korea, in 2004 and 2006, respectively.

- 10:40 Connection Sharing on top of a Virtualization Layer to Support Vehicular Cloud Computing
- The vision of vehicular cloud computing (VCC) is to harness the wealthy resources contributed by groups of vehicles to enable innovative information services on the road. Thus far, the scenarios envisaged for this paradigm are limited by the challenges derived from the mobility of the vehicles, to the point that most of the proposals in the literature have merely dealt with vehicles in parking lots, stuck in traffic jams or moving as a flock for a long time. We present an approach to overcome those limitations by engaging the vehicles in collaboration to emulate an infrastructure of stationary virtual nodes, which can be made responsible for computing, sensing, storage and communication tasks. We present the architecture and the main procedures of the proposal, along with simulation results for the VCC service model known as Network as a Service (NaaS), aimed as exploiting the various connections available to groups of connected vehicles as an integrated whole.Presenter bio: Jack Fernando Bravo Torres, PhD in the Department of Telematics Engineering at the University of Vigo, Spain.

- We aim through this work to investigate the optimal deployment of roadside units, the stationary component in the vehicular network, in order to improve the performance, the reliability and the connectivity of the network. RSUs have a critical role in safety applications but also in infotainment applications. Hence, spreading RSUs should take into account to cover with its best effort the dark zones and to serve the biggest number of vehicles with continuous services all with keeping in the range of the deployment budget. To reach our objectives, we consider stationary and mobility-based statistics to model our traffic network as a graph with weighted links showing the importance of each link in terms of amount of vehicles, hazardous level, and mobility-based parameters (speed, speed limit, average of connected time). Then, all the potential positions are designated and two different algorithms, Knapsack and PageRank, are applied to select the optimal set of RSUs positions within the cost range. Finally the output set of each algorithm is evaluated against real traffic records and statistics to show the network performancePresenter bio: Fethi Filali is the Head of Technology Development & Applied Research at Qatar Mobility Innovations Center (QMIC).

- 11:20 Emergent Behaviors and Traffic Density among Heuristically-Driven Intelligent Vehicles using V2V Communication
- In this paper, we study the global traffic density and emergent traffic behavior of several hundreds of intelligent vehicles, as a function of V2V communication (for the ego vehicle to perceive traffic) and path-finding heuristics (for the ego vehicle to reach its destination), in urban environments. Ideal/realistic/no V2V communication modes are crossed with straight-line/towards-most-crowded/towards-least-crowded path- finding heuristics to measure the average trip speed of each vehicle. The behaviours of intelligent vehicles are modelled by a finite state automation. The V2V communication model is also built based on signal propagation models in an intersection sce- nario and a Markov-chain based MAC model. Our experiments in simulation over up to 400 vehicles exhibit attractive insights: 1) communication's impact is positive for the performance of the emergent vehicles' behaviour, however, 2) the path-finding heuristics may not obtain their expected collective behaviour due to the communications errors in realistic road environment.Presenter bio: Dr. Oyunchimeg Shagdar is a researcher at the institute VEDECOM, FRANCE.

We focus on the prediction at the receiver vehicle and suggest two novel frameworks, which allow real-time and short-term prediction whether a predefined application-specific QoS will be maintained in the near future. Both frameworks are developed based on the measurement data which was gathered through the 4.5 month of the field trials in the simTD project.In our paper we also suggest an optimization method to increase prediction accuracy and validate both frameworks through additional real-world measurement campaign. The main advantages of both developed methods comparing to the existing work is their completely generic nature and simultaneously high performance in urban, rural and highway environments as well as low to no memory requirements. We demonstrate that in low network density scenarios prediction accuracy can reach up to 97%.Presenter bio: Tetiana Zinchenko is currently working as an engineer in Volkswagen group research in the field of mobile services.

Its objective is to provide differentiated services to vehicular networks which are delay-sensitive and requires high communication throughput.

We propose a Markov chain-based analytical model that depicts accurate representation of the IEEE 802.11p MAC sub-layer. We take into account the internal collision probability that occur among different Access Categories (ACs) in the same vehicle. We also consider an unsaturated traffic condition and include the probability of finding the medium busy when sensed during the backoff period.

- 13:30 A Novel Forecasting Algorithm for Electric Vehicle Charging Stations
- In this paper, a recently proposed time series forecasting algorithm, Modified Pattern-based Sequence Forecasting (MPSF), is compared with three other algorithms. These algorithms have been applied to predict energy consumption at individual EV charging outlets using real world data from the UCLA campus. Two of these algorithms, namely MPSF and k-Nearest Neighbor (kNN), are relatively fast and structurally less complex. The other two, Support Vector Regression (SVR) and Random Forest (RF), are more complex and hence require more time to generate the forecast. Out of these four algorithms, kNN with k=1 turns out to be the fastest, MSPF and SVR were the most accurate with respect to different error measures, and RF provides us with an importance computing scheme for our input variables. Selecting the appropriate algorithm for an application depends on the tradeoff between accuracy and computational time; however, considering all factors together (two different error measures and algorithm speed), MPSF gives reasonably accurate predictions with much less computations than NN, SVR and RF for our application.Presenter bio: Mostafa Majidpour is a PhD candidate in the Electrical Engineering department and Smart Gird Energy Research Center at UCLA, developing Statistical and Machine Learning algorithms to analyze various data in the context of smart grid.

The outcome of each of these methods have been used as the input to a prediction algorithm to forecast the EV load in the next 24 hours at each individual outlet. The data is real world data at the outlet level from the UCLA campus parking lots. The Median imputation improved the prediction results.

- 14:10 Intelligent Driver Support: Integration of Coupon Services into On-Board Infotainment Systems
- There are exist various types of coupon- or special offer-based scenarios. For example, one can have a set of coupons (e.g., in an electronic form) and he/she has to choose the right coupon and the right store/service depending on the current situation (location, needs, etc.). Another possibility is when one receives notifications for coupons available at nearby stores/service and can buy those, which are needed at the moment. It is also possible that instead of coupon, there are available special offers in the area (e.g., discount for coffee if you buy 30 liters or more of gas) to choose from. From the user's point of view, all these scenarios have to be processed in the same way. This is especially important for drivers, who cannot be distracted from driving. The development in-vehicle electronic systems has recently made a significant step forward. Such systems have transformed from simple audio players to complex solutions (referred to as "infotainment systems") that enable communication with smartphones, sharing information from different vehicle sensors, information delivery through in-vehicle screen or stereo system (e.g., Ford SYNC, GM OnStar MyLinkTM, Chrysler UConnect®, Honda HomeLink, Kia UVO, Hyundai Blue Link, MINI Connected, Totyota Entune, BMW ConnectedDrive, Apple CarPlay, Google's Auto Link, etc.). One of systems integrating the coupon idea into Ford's AppLink is Roximity: "ROXIMITY enables registered users to input individual preferences and interests. Then, as users drive, walk or bike past a restaurant or store that might have a deal or special they would find appealing, a push notification is sent to their phone informing them of what they are near." However, taking possibilities provided by the modern infotainment systems let us provide a better support. Let us consider the following scenario. One drives through an area. The system identifies that (s)he needs to re-fuel the car (based on the automatic gas level identification) and have some rest (based on the automatic fatigue level identification depending on how long one has been driving). Conventional driver support would react on the first of the two events (low gas level or high fatigue level) and propose the nearest corresponding point of interest (POI). The most advanced systems might take into account the preferred by the driver brand. However, it would be more convenient to react on both events (taking into account the gas level and fatigue level change in the future) and propose a gas station and cafeteria of preferred brands with good feedback from their customers, where one can have a discount due to available coupons or special offers. In order for such a mechanism to operate efficiently, it requires a continuous adjustment of the services information about the driver preferences. This can be done through collecting information and knowledge from different sources. Among those, mentioned in the taxonomy, the following ones can be mentioned: 1. User feedback (the driver can increase or reduce the utility of a certain service). 2. Initial driver profile (the driver can fill out the initial preferences in his/her profile). 3. Analysis of driver decisions (the system can analyse if the driver followed the proposed solution, or which solution is preferred if several alternative solutions are presented to the driver). 4. Analysis of decisions of drivers with similar interests/habits. The first two information sources are reliable, however, in real life it is very unlikely, that the driver will provide such feedback, and information once entered into the driver's profile will be outdated after some time. The third information source is less reliable, but such information will never be outdated and development of learning algorithms can significantly improve such feedback. The fourth information source is the least reliable. It originates from the methods of collaborative filtering used in collaborative recommendation systems, which are currently being widely developed. The interaction between services is supported by the usage of AppLink for interaction with the vehicle and the driver. In addition to the information already stored in the services (associated databases, user settings, revealed preferences, etc.), they acquire the following information from other services, namely: - Gas station advisor obtains current car location, gas level, and predefined driver preferences. - Restaurant advisor obtains current car location and predefined driver preferences. - Coupon service provides information about available coupons and special offers. - Recommendation service obtains driver's schedule from his/her smartphone to estimate current time restrictions, predefined driver preferences and information obtained from the above mentioned sources. The generated solutions are transferred to the AppLink screen so that the driver could choose the most appropriate one, and to the in-car navigation system. If a coupon is needed to be paid for, the driver can do it directly from the in-car system. There is a number of business models for coupon deal Web sites, e.g. having a percentage of the promotion revenue or of the sold coupons. Any of these business models could be used in the proposed scenario. The main difference that can attract the customers is the way of offering the coupons unobtrusively, in the right time as an added-value feature of an information support system.Presenter bio: Head of laboratory "computer aided integrated systems" of St.Petersburg intitute for informatics and automation of Russian Academy of Science and internation laboratory "intelligent technologies for socio-ciberphisical systems" of ITMO University.

We address this problem by developing a GPS-based solution that equips roadside workers and vehicles with GPS units to estimate the trajectory of oncoming traffic, and estimate whether worker strike is imminent. The results of our study show that our approach is 91% accurate in alerting the worker and vehicle of collisions and near misses. Furthermore, accurate warnings can be provided 5-6 seconds before any potential collision, allowing time for mitigating solutions.Presenter bio: Jason Forsyth is a PhD candidate in the ECE department at Virginia Tech.

- 13:50 Optimised Consensus for Highway Speed Limits via Intelligent Speed Advisory Systems
- In this paper, an application based on the Intelligent Speed Adaptation (ISA) system is proposed to reduce CO2 emissions of vehicles running on the highway. We apply the idea of optimised consensus to solve the emission optimisation problem in a simplified highway scenario through simulation study. Our approach shows that total CO2 emissions of vehicles can be minimised if all vehicles follow the reference speed signal derived from the ISA.

- 14:30 Early Estimation of Multi-Objective Traffic Flow
- Intelligent Transportation Systems (ITS) have come a long way targeting problems such as increasing emissions and growing vehicle numbers. Current approaches address a variety of objectives including congestion management, collision avoidance, energy-efficiency and emission reduction. However, respective solutions typically are designed for and tailored to a predefined set of objectives. Consequently, the effects of drastically changing objectives cannot be assessed easily. To address this situation we present a lightweight approach to estimating multi-objective traffic flow early in systems engineering using non-deterministic models and stochastic optimization techniques. We demonstrate the feasibility of the framework using a basic traffic scenario and conclude with an outlook.Presenter bio: Dominik Ascher received his B.Sc. degree in Information Systems in 2013 and is currently pursuing the M.Sc. degree in Information Systems at Technical University of Munich.

- Lane-level roadway modeling is a key enabling technology in the deployment of automated vehicles and connected vehicle systems. A variety of applications for these systems would be enabled by the availability of up-to-date lane-level maps; however, current mapping solutions lack this resolution and are not dynamically updated. This paper will present a method for passively collecting vehicle basic safety messages (BSM), as defined by SAE J2735, through roadside equipment (RSE), and a set of learning algorithms that utilize the information contained in the BSM to produce a local map of the roadway at an accuracy level of individual lanes. This map can then be transmitted back to vehicles in the local area as a set of sparse GPS waypoints.Presenter bio: PAUL A.

- 13:30 Performance Analysis of Alamouti Coded OFDM Systems over Wideband MIMO Car-to-Car Channels Correlated in Time and Space
- In this paper, the performance of Alamouti coded orthogonal frequency division multiplexing (OFDM) systems over car-to-car (C2C) fading channels correlated in time and space is analyzed. Taking different geometrical scattering models into account, a generalized expression of the time-variant transfer function (TVTF) is derived for wideband multiple-input multiple-output (MIMO) C2C channels. We present a generalized expression for the bit error probability (BEP), which will be used to describe the performance of Alamouti coded OFDM systems over different types of C2C channel models, such as the rectangle model, the tunnel model, the street model, and the curve model. The effect of the maximum Doppler frequency and the antenna element spacing on the system performance is discussed. Furthermore, the proposed generalized model allows us to study the impact of the parameters of the geometrical model on the BEP. The proposed procedure enables us to investigate the system performance using different kinds of C2C fading channel models in a straightforward and time-efficient manner.Presenter bio: Matthias Pätzold received the Dipl.-Ing. and Dr.-Ing. degrees in electrical engineering from Ruhr-University Bochum, Bochum, Germany, in 1985 and 1989, respectively, and the habil. degree in communications engineering from the Technical University of Hamburg-Harburg, Germany, in 1998.

- 13:50 Vehicle Node Localization without GPS in VANET
- In Intelligent Transport System (ITS) there is a new kind of ad hoc network: Vehicular Ad-hoc Networks (VANET). In VANET, vehicles get useful information by communicating with each other or with a roadside unit. The location information is important in VANET. It is easy to obtain the locations of vehicle by GPS technology. However, there still are some unexpected problems such as not always being in signal coverage or not being strong enough for some applications. It is necessary to develop additional localization techniques to overcome GPS limitations. In this paper, we discuss localization techniques via V2V and V2R communications in VANET when there is no available GPS information, design a dynamic positioning system based on IEEE802.11p and IEEE1609 standards, and simulate positioning algorithms of DV-Hop, RSSI and MDS-MAP.Presenter bio: Wei Xiong was born in Hubei China in 1986.

- 14:10 A Handoff Algorithm for Packet Loss Optimization in Vehicular Radio-over-Fiber Picocellular Networks
- In mobile picocellular network topologies a very critical issue is the handoff procedure in conjunction with the corresponding packet loss, due to the limited overlapping areas between adjacent cells. Handoffs and packet loss are more frequent and even more critical in picocellular vehicular networks, since the afore-mentioned limitation is combined with the high velocities of the mobile end-users. In this paper we present a mathematical model that depicts the packet loss results of a promising handoff algorithm, i.e., the "moving extended cell", for vehicular Radio-over-Fiber (RoF) picocellular networks at 60 GHz against the corresponding "traditional" handoff algorithm, respectively. Furthermore, we evaluate and verify the mathematical analysis with a simulation study, and, finally, we present the respective results, which reflect that moving extended cell handoff algorithm can be applied to minimize packet loss in vehicular RoF picocellular networks.
- 14:30 VeSCA: Vehicular Stable Cluster-based Data Aggregation
- In-network data aggregation is a promising technique to reduce data transmission that contributes the effective usage of bandwidth and co-existence of different application in vehicular ad-hoc networks (VANET). Early aggregation schemes in VANET are grouped into two categories; structure free and structure based data aggregation. In structure-free data aggregation, vehicles apply pre-defined delay value before forwarding a data packet to the next hop. On the contrary, structure based data aggregation uses a hierarchical structure, based on either road information or vehicles, to perform data aggregation. To provide efficient and scalable VANET communication, data aggregation is essential for reducing per vehicle bandwidth requirements. In this paper, we propose a multi-hop structure based data aggregation method namely VeSCA where mobile nodes are grouped based on relative mobility with minimum overhead cluster construction and cluster members apply data aggregation before forwarding data packet to the parent node. Using various key metrics including data aggregation ratio, delay and aggregated data delivery ratio, we demonstrate superior performance VeSCA compared both previous cluster based data aggregation and alternative aggregation mechanism via extensive simulations in ns-3 with the vehicle mobility input from the Simulation of Urban Mobility (SUMO). VeSCA achieves over 70% aggregated data packet delivery ratio with aggregation ratio 40%.Presenter bio: Seyhan Uçar received his B.Sc. degree in Computer Engineering from İzmir Institute of Technology in 2011.

- 14:50 Propagation Measurements in 5.8GHz and Pathloss Study for CEN-DSRC
- The Dedicated Short-Range Communications (DSRC) technology in the $5.8$ GHz band is a key enabler to support a safer and more efficient vehicular transportation in the future. The chosen $5.8$GHz frequency band is therefore of great interest for us to study the propagation of signals under various environments. In this paper we investigate and record the propagation affects of $5.8$GHz radio signals in an urban and sub-urban like environments with experiments conducted in the city of Melbourne for an infrastructure to vehicle (I2V) use case. The experiments were conducted for a T-R separation from $20m$ to $150m$ with line of sight conditions for the three chosen environments with and without the vehicle for comparisons as described in the paper. Based on the measurements we estimate the pathloss exponent and the shadowing standard deviation for the chosen scenarios. More interestingly our results also show a constant pathloss for the measurements with the car when compared to the measurements without the car for different scenario.Presenter bio: Gianmarco Baldini (M'08) received the Italian Laurea degree in electronic engineering from the University of Rome "La Sapienza," Rome, Italy, in 1993, with specialization in wireless communications.

- 13:30 Fair Downlink Traffic Scheduling for Energy Sustainable Vehicular Roadside Infrastructure
- Many vehicular roadside units (RSUs) or infrastructures are deployed along the highways to provide information service. However, most of them are powered by renewable energy, such as solar power, due to the unavailability or prohibitive expensive of the wired electrical power. In this paper, the timeslot based traffic scheduling problem is considered with the objective to fairly and energy efficiently serve the vehicles. The contact durations between the vehicles and the RSU are slotted into timeslots, during each of which one unit of the traffic can be transmitted from the RSU to one vehicle, and then one unit of vehicle's requirement can be satisfied. The downlink traffic scheduling cost is defined as the transmission energy cost to deliver the traffic. The fairness of the traffic scheduling strategy is evaluated by the Jain's fairness index of the unsatisfied vehicle requirements. The proposed problem is formulated as a three-step optimization problem. To address the difficulty of the three-step optimization problem, a flow network based algorithm is proposed. Both the offline and the online traffic schedule strategies are derived. Simulation results show that the derived offline traffic scheduling strategy outperforms the original energy optimal traffic scheduling strategy in terms of fairness, while the transmitted traffic and the transmission energy cost remains almost the same. The derived online traffic scheduling strategy outperforms the GMCF algorithms in terms of fairness, at the expense of larger transmission energy, and with the same total transmission traffic.Presenter bio: Zhongjiang Yan received the B.E. and PhD degree in telecommunication engineering from Xidian University in July 2006 and 2011, respectively.

- 13:50 A Flexible Backhaul Architecture for LTE-Advanced
- The proliferation of data-hungry smart electronic devices, such as smartphones and intelligent vehicles, has driven the capacities of current mobile communication systems towards their limits. To tackle this formidable challenge, 3GPP Long Term Evolution has recognized network densification with low-power small cells (SCs) as a key paradigm in the upcoming 5G communication system. In this article, we introduce a novel wireless backhaul framework for small cell networks by introducing a new backhauling component, which is referred to as Type-A relay. This new entity is capable of communicating simultaneously with two macrocells by leveraging the downlink resource of one cell as well as the uplink resource of the other, which effectively operates in full-duplex mode without incurring additional costs to acquire carrier resources. The proposed approach offers increased architectural flexibility and substantial capacity enhancement over the current LTE relaying-based solutions. Simulation results are presented to demonstrate the strong potential of the proposed approach in future 5G communication systems.Presenter bio: Yi Shi(S'06-M'10) received the Ph.D. degree in Electronic and Computer Engineering from The Hong Kong University of Science and Technology, Hong Kong, in August 2010.

- 14:10 Messages Prioritization in IEEE 802.15.4 based WSNs for Roadside Infrastructure
- Wireless Sensor Networks (WSNs) have gained a wide popularity for real-time events monitoring and detection due to their high accuracy and ease of deployment. Therefore, they have become increasingly prevalent solutions in several application domains such as health-care, transportation, etc. Many studies in the literature have focused on optimizing the energy consumption of the wireless sensors in order to ensure their autonomous operation for longer periods. Some applications of WSNs, however, have strict delay requirements due to the nature of the information being transmitted. This delay should be kept as short as possible to ensure timely and efficient reaction of the system, such as a Traffic Management System (TMS) dealing with an incident on the road. In this context, we propose, in this work, two novel schemes to improve the transmission delay of prioritized messages in WSNs deployed in road networks to report regular traffic as well as event-driven (i.e. incidents) information. These schemes consist in an improvement of the backoff computation mechanism at the MAC layer of IEEE 802.15.4 standard protocol, in addition to an original dual mode operation mechanism, in order to speed up the transmission of event-driven messages, while keeping the transmission delay of periodic messages reasonably low. Simulation results show that our schemes succeed to reduce the transmission delay of event-driven messages and achieve a very high packets delivery ratio.
- 14:30 Performance Analysis of a Combined STC-SVD MIMO-OFDM System
- Multiple-Input Multiple-Output (MIMO) systems using orthogonal frequency-division multiplexing (OFDM) technique are considered as promising solutions for the next generation communication systems. MIMO-OFDM systems can be enhanced using Space-Time Coding (STC). In this paper we introduce a combined Alamouti Space Time Block Coding/Repetition coding (STBC/STRC) with Singular Value Decomposition (SVD) system for future generation WLANs. The introduced system improves the Symbol Error Rate (SER) performance of MIMO-OFDM systems. Two schemes are applied on a (2×2) MIMO-OFDM antenna configuration. MATLAB® simulations show that the proposed system performed better over its standalone Alamouti-STC and SVD counterparts. Moreover, we show that better performance is not associated with a significant increase in the computational complexity of the algorithm, especially in the STRC-SVD case.Presenter bio: Sherif M.

- 14:50 Propagation Model for Vehicle to Vehicle LOS Communication in Foliage Scenario
- Available propagation models for Vehicle to Vehicle communication in foliage scenario are based on empirically derived formulation, where attenuation is caused by the absorption of vegetation when propagation through the body of vegetation. In this paper, we analyze the scenario where high-profile trees along both roadsides with a LOS communication link between testing vehicles. We present a multi-ray model to simulate the propagation loss and validate the model with raw data from measurements performed in the rural area of Lippstadt, Germany. Two dominant reflection rays aroused by vegetation and ground respectively are mainly considered for computational simplicity. The proposed model reflects the condition observed from our measurement results, and has a high performance in estimating the attenuation.Presenter bio: Yuan Chen received B.Eng. degree in communication engineering from Tongji University, Shanghai, China, in 2012.
