[Abstract]:According to the evaluation requirement of mobility support for IEEE 802.11p protocol, a vehicle networking application scenario based on IEEE 802.11p protocol is constructed, and the vehicle arrival model in the vehicle networking system is described by Poisson process.The simulation scene is built based on Veins platform and the simulation parameters are set up. The traffic density is tested and analyzed from the aspects of end-to-end delay, packet loss rate and throughput.The effect of vehicle speed on the performance of IEEE 802.11p and the applicability of IEEE 802.11p in vehicle networking environment.The test results show that the vehicle speed has a great influence on the performance of the vehicle network based on IEEE 802.11p protocol, while the traffic density has little effect on the performance. Meanwhile, the IEEE 802.11p protocol is suitable for active road safety applications and helps to improve the efficiency of cooperative traffic.
