IEEE802.11p无线车载自组网络协议的性能分析与模拟

Performance Analysis and Simulation of IEEE 802.11p Wireless Protocol in Vehicle Ad-hoc Networks

IEEE 802.11p WAVE(Wireless Access in Vehicular Environment)通信协议主要用于高速率的车辆之间(V2V:Vehicular toVehicular)以及车辆与路边基础设施之间(V2I:Vehicular to Infrastructure)的资料数据交换。文章主要对NS-2下IEEE 802.11p的网络性能的模拟情况进行了研究。首先介绍了WAVE系统以及IEEE 802.11p协议标准,在此基础上采用NS-2仿真软件对IEEE802.11p协议进行模拟,同时还对IEEE 802.11a协议进行仿真,并对两者仿真结果进行分析总结。验证了IEEE 802.11p协议是专为车载无线网络设计的一种协议的合理性。

IEEE 802.11p WAVE（Wireless Access in Vehicular Environment） protocol is mainly used for high-speed information and data exchange between vehicles（V2V： Vehicular to Vehicular）,and between vehicles and roadside infrastructure（V2I： Vehicular to Infrastructure）.The performance of IEEE 802.11p using NS-2 simulator has been studied in this paper.First of all,the WAVE system and the IEEE 802.11p protocol standards are investigated.On this basis,the paper uses NS-2 simulation software to simulate the IEEE 802.11p and IEEE 802.11a.The simulation results are analyzed and summarized.It is verified that the IEEE 802.11p protocol is designed reasonably for the vehicular wireless network.
