Workshop on MIMO and Cognitive Radio Technologies in Multihop Network

Friday, 12 June 2015 • 09:00 – 18:00

WS-12: MIMO and Cognitive Radio Technologies in Multihop Network (MIMOCR)

Organizer: Xuemin (Sherman) Shen (University of Waterloo, Canada)

Multiple-input multiple-output (MIMO) and cognitive radio (CR) technologies have gained increasing attention recently. MIMO effectively increases data throughput without using additional radio spectrum, and CR exploits the existing wireless spectrum opportunistically. MIMO and CR effectively address the problem of limited available spectrum. However, the distributed coordination of MIMO and CR functionalities in a multihop ad hoc network remains to be addressed. The non-trivial coupling of ad hoc networks with MIMO and CR will pose new challenges on protocol design and resource management, create exciting new topics in MIMO and CR research pertaining to optimal leveraging of local information, and greatly advance both the networking and communication technology of decentralized architecture. The objective of the workshop is to bring together practitioners and researchers from both academia and industry in order to have a forum for discussion and technical presentations on applying MIMO and CR technologies to ad hoc networks.

Welcome Session

Keynote-1: Channel-Quality-Aware Opportunistic Relaying, Cooperative Cognitive Radios and All That...

Buffer-aided channel-quality-aware opportunistic relaying allows thelinks momentarily benefitting from the best channel quality to beactivated, but naturally, this requires the storage of the hithertountransmitted information, which imposes a delay. Hence the integrityversus delay trade-offs of these networks have to be investigated.The specific routing strategy of ad hoc networks also plays a pivotalrole in determining their overall performance. Diverse objectivefunctions may be conceived and optimized at the potential erosion ofthe remaining performance metrics. As an enhanced design approach,multi-objective optimization may be pursued, where additionalconstraints may be imposed in the interest of finding the optimumPareto front without an exhaustive brute-force search.The efficient spectral access of multiple Primary Users (PUs) andCognitive Users (CUs) may be arranged in cooperative CognitiveRadio (CR) networks with the aid of game-theoretic techniques, wherethe PUs negotiate with the CUs concerning the specific amount ofrelaying and transmission time, whilst reducing the requiredtransmission power or increasing the transmission rate of the PU.

Keynote-2: Cognitive Radio for 5G and Future Cellular Networks

The 5G and future cellular networks are expected to support the explosive growth of mobile data for various types of services. Besides increasing the spectral efficiency and exploring unused spectrum, the need for spectrum sharing to support the deployment of various networks becomes unavoidable. Over the past decade, there have been a lot of research and development activities devoted to the spectrum sharing research. In this talk, I will highlight the key cognitive radio ideas and technologies that could contribute to the development of 5G and future cellular networks, including, e.g., spectrum refarming, LTE-U, D2D communications, and software-defined wireless network access.
