摘要
主要针对VANETs网络中的三个典型路由协议AODV、DSDV、DSR进行了仿真分析,通过改变节点数,对数据分组的平均端到端时延、归一化路由开销和分组递交率这三个重要性能指标做了对比,分析了三种协议适用的网络环境,了解它们的可扩展性,仿真的结果表明DSDV协议可扩展性差,ADOV协议和DSR协议有一定的可扩展性。
Three typical routing protocols of AODV, DSDV and DSR in VANETs were simulated and analyzed. By adjusting the number of nodes, three indicators of average end-to-end delay, normalized routing overhead and delivery ratio of packets were compared for these routing protocols. Network environments suitable for these three protocols were analyzed. Their scalabilities were addressed. Simulation results show that DSDV protocol has worse scalability, while AODV and DSR protocols have better scalabilities.
