【摘要】：针对IEEE 802.11p协议移动性支持的评估需求,构建基于IEEE 802.11p协议的车联网应用场景,利用泊松过程描述车联网系统中的车辆到达模型。基于Veins平台搭建仿真场景并对仿真参数进行设置,从端到端延迟、丢包率、吞吐量方面测试并分析车流密度、车辆行驶速度对IEEE 802.11p性能的影响以及IEEE 802.11p应用于车联网环境的适用性。测试结果表明,车辆行驶速度对基于IEEE 802.11p协议的车联网性能影响较大,而车流密度对其性能影响较小,同时IEEE 802.11p协议适用于主动道路安全应用且有助于提高合作交通效率。
[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.
