Performance evaluation of information propagation in vehicular ad hoc network

Intelligent transportation systems are based on the acquisition and dissemination of traffic information timely and accurately. Wireless communication technology has made this possible. Vehicles equipped with communication module and road-side stations constitute vehicular ad hoc network (VANET), in which traffic information is collected and shared. On the basis of the most forward within radius (MFR) routing protocol, this article studies the connectivity of information propagation in inter-vehicle communication, mainly focuses on packet loss rate, packet transmission distance and effective coverage range of road-side station. We use such indicators to evaluate the performance of inter-vehicle communication for different equipped rates, wireless communication ranges and typical distributions of vehicle space headway, which can be reference in practical deployment of VANET. Simulation results are shown as well.
