Abstract
Vehicular communication system is a key part of intelligent transportation system (ITS) while vehicle safety communication (VSC) is a major target of vehicular communication. The use of radio frequency identification (RFID) system for vehicular communication has been proposed for pedestrian-safety. In this paper, an extended RFID system and infrastructure for vehicle safety communication through co-operative routing of information on vehicles' sudden motion and direction changes and warning messages for post-accident scenarios is proposed. It also provides a demonstration on the structure of warning codes and flow of information within the system and the vehicular ad-hoc network (VANET) for the vehicle safety. This paper also includes the simulation results for line-of-sight (LOS) communication and a special non-line-of-sight communication (NLOS) to observe the co-operative distance covered by co-operative routing and the related bit error rates (BERs). Doppler shift effect is also considered in the simulation.
