Vehicular Communications and Applications

- Opportunities and Challenges

Wai Chen



 Significant research efforts have been aimed at integrating communication and computing technologies into vehicles and roadway infrastructure. The objective is to improve preventive vehicle safety, reduce traffic congestion, and enable new applications such as remote diagnositics, mobile commerce, and entertainment. Industrial and governmental efforts are underway to accelerate the introduction of vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications functions, e.g., EU C2C-CC, SeVeCom; US VII, CAMP/VSC-2; Japan AHS / Smartway and ASV, ISO/CALM, IEEE WAVE, ETSI TC ITS.

 Much recent research have been directed at developing vehicular ad hoc networking technology as an enabler for many emerging vehicle safety and information applications. The combination of requirements of the emerging applications and characteristics of the roadway environments poses new challenges to the design of vehicular networking systems to achieve dependable, fast and secure V2V and V2I communications. The mobility of vehicles can result in rapid network topology changes, node density fluctuations and constantly changing environment conditions. This could overwhelm the limited bandwidth of the radio links if the communication protocols are not well designed. Achieving security for applications and networking, and maintaining driver privacy in roadway envirnments are also crucial challenges, and as such have received much attention.

 This talk will first overview examples of vehicle safety and information applications and associated technical challenges. The talk will then outline some major current efforts in developing V2V and V2I communications technologies. The talk will conclude by sharing some thoughts on transitioning the existing technical and experimental results into cost-effective and deployable solutions for fully-networked cars via further R&D activities and standardization efforts.


Wai Chen received his B.S.E.E. degree from Zhejiang University; M.S.E.E., M.Phil., and Ph.D. degrees from Columbia University in the City of New York. Currently, he is with Applied Research, Telcordia Technologies Inc. (formerly known as Bellcore) where he is a Chief Scientist and Director of Ubiquitous Networking and Services Research. Dr. Chen has been leading a vehicular communications research program in collaboration with a major automaker, since 2000, on automotive networking technologies for vehicle safety and information applications. He has also been the Principal Investigator of several government funded projects on advanced networking technologies research. Dr. Chen is the Series Editor for Automotive Networking-Technology, Design, and Applications of the IEEE Communications Magazine, served as a Guest Editor for Special Issue on Inter Vehicular Communication (IVC) for IEEE Wireless Communications Magazine (2006), the IEEE Distinguished Lecturer (2004-2006), the Co-Chair for Vehicle-to-Vehicle Communications Workshop (V2VCOM 2005-2008) co-located at IEEE Intelligent Vehicles Symposium, and the Co-Chair for the IEEE Workshop on Automotive Networking and Applications (AutoNet 2006-2008) co-located with IEEE Globecom, and the Co-Chair for the upcoming IEEE Vehicle Networking Conference 2009. His current research interests are vehicle communications and ITS applications, and mobile wireless communications systems.
