A clustering-based multi-channel Vehicle-to-Vehicle (V2V) communication system

Traffic safety in any type of transportation systems is a global concerned issue. In this paper, we propose a clustering-based multi-channel Vehicle-to-Vehicle communication system to provide traffic accident avoidance mechanism. In the proposed system, vehicles are self-organized into different clusters, and the traditional single common medium in ad hoc networks has been divided into multiple control channels and a single data channel. An infrastructure-based TDMA/CDMA technique is designed for the intra- and inter-cluster communications via data channel. The IEEE 802.11 CSMA/CA protocol is utilized by control channels. Our system is evaluated by extensive simulations. The simulation results show the proposed system can support traffic safety efficiently.
