Workshop on Dependable Vehicular Communications (DVC)

Vehicular communication and applications: who depends on whom?In this talk, we look at the "co-design" of inter-vehicular communication and applications. The communication and networking community has primarily followed the track to come up with an application-agnostic "best" communication strategy by focusing their research work on beacon-based communication and aspects of congestion control. More recently, protocols for cooperative driving applications have been specified and their range of operations has been checked against the characteristics of the assumed vehicular communication systems. We look at rear end collision avoidance, virtual traffic lights, and remote diagnosis and update and discuss dependability issues as well as methodologies to check for fail-safety. We also show the differences in dependability definitions with respect to safety as well as to traffic performance. In addition, we address some research challenges, both scientific and pragmatic.V2X Deployment: Safety and BeyondThe safety use cases of V2X communication have received a lot of attention and are fairly well understood. In this talk we explore two questions: 1) How will deployment unfold in the US and other regions? 2) What is the V2X story after initial deployment? We will consider differences in strategy in the US, Europe, and Japan, including emphases on classes of application and assessments of benefits. We discuss potential technical and policy challenges, including standardization, certification, security, congestion management, and spectrum. We also look at the role that alternate technologies, including LTE, may play in delivering some V2X services. Looking further into the future, we also consider the challenge of technology evolution and the large opportunities for innovation in the application space.
