摘要
从无线车联网的实际需求出发,提出了一种双层拓扑结构的网络模型,并通过NS2软件进行模拟仿真,对簇树、AODVjr和ZBR 3种路由协议在车联网应用环境下的性能做出了详细分析。结果表明ZBR协议能够在保持较高分组递交率和较短时延的前提下,大幅降低网络的控制开销。
Considering the fact requirement of wireless network among vechicles,a network model named double-deck topology structure is proposed,and is simulated by NS2.At the same time,the performance of three kinds of routing protocol,which are Cluster-Tree,AODVjr and ZBR,in the application of wireless network among vechicles is studied.The simulation experiment demonstrates that ZBR routing protocol can decrease control overheard while keeping higher packet delivery rate and shorter time delay.
