摘要
随着无线通信技术的不断发展,车载环境下无线接入(Wireless Access in Vehicular Environments,WAVE)技术越来越受到人们的关注。现今车载环境下的无线网络接入技术采用了多种协议,主要协议有IEEE 802.11p WAVE协议和IEEE 1609.4 WAVE协议。本文从两协议的协议结构、功能以及固有算法等方面进行比较分析,并提出了对IEEE 802.11p协议的算法改进研究,提高了协议的平均时延、丢包率以及吞吐量的性能。并且通过Matlab仿真表明其有效性。
With the development of wireless communication technology,People pay more and more attentions to Wireless Access in Vehicular Environments technology.Nowadays WAVE networks has adopted some protocols,mainly including IEEE 802.11p protocol and IEEE 1609.4 protocol.In this paper,we compare the two protocols from Frame formats,Protocol Functions and intrinsical algorithm,also propose improvement to every protocol algorithm,and improve the average delay,package loss and throughput.We testify the effectiveness through software Matlab.
