Metropolitan VANET: Services on the Road

The application of mobile communication technology to support road traffic constitutes a challenging, but at the same time very promising working area for research and development. Services reach from vehicular safety applications including collision and other safety warnings to non-safety applications like real-time traffic congestion and routing information, high-speed tolling, mobile infotainment, and many others. The creation of high-performance, highly reliable, highly scalable, and secure wireless vehicular ad hoc network (VANET) technologies, though, presents an extraordinary challenge to the wireless research community: a high degree of communication reliability is needed under unfavorable channel conditions. Clearly, the specificity of VANETs in terms of mobility behavior and applications scenarios and requirements makes VANET research an exciting and demanding application- and purpose- driven sub-discipline of wireless networking. In this talk, we discuss the challenges and opportunities of VANETs in metropolitan scales. A concrete case in Shanghai was also studied.
