摘要 Ad hoc移动网络是一种无任何有线基础设施的多跳、临时性自治系统,而路由协议是Ad hoc网络体系结构中不可缺少的组成部分,所以路由协议的研究十分重要。文中使用NS2仿真软件对Ad hoc网络中DSDV、DSR和AODV三种典型路由协议,从分组投递率、端到端平均时延和路由负荷三方面进行性能仿真分析。仿真对比结果表明:DSDV的平均时延和路由负荷要小于AODV和DSR,但分组投递率性能不如AODV和DSR。根据它们的这些特点分析得出:AODV协议适用于网络拓扑变化频繁的情况;DSR协议适用于节点较少、网络变化较小且对时延要求不高的情况;而DSDV协议更适用于网络节点移动速度较小的情况。 Ad hoc mobile network is a multi - hop, interim self - government system without any cable infrastructure, and the Ad hoc routing protocols are indispensable components of the network architecture. So it is very important to study the routing protocols. In this paper, three typical routing protocols （IT）SDV, DSR and AODV） of Ad hoc network were simulated based on NS2 simulation software. Then it evaluated the simulation results with three performance parameters：packet delivery rate,average end - to- end delay,routing load. The simulation results showed that the average end - to - end delay and routing load of DSDV are less than DSR and AODV,but packet delivery rate is worse than which of DSR and AODV. The conclusion can be drawn according to the characteristics： AODV applies to the situation with frequent changes in network topology;DSR applies to the situation with fewer nodes and less demanding in network delay. But DSDV is suitable for the situation in which node traveling speed is lower.
