【摘要】 介绍了Ad Hoc网络中常见的三种路由协议DSDV、DSR和AODV,针对网络拓扑结构的变化,设计了两种仿真方案,利用NS2仿真工具对三个协议进行了仿真。通过分析报文投递率和平均端到端时延比较了三个协议的性能。仿真结果表明,AODV具有优秀的综合性能,更适合于节点移动速度快且网络拓扑结构变化频繁的网络。更多还原

【Abstract】 This paper introduces three main routing protocols including DSDV,DSR,AODV of the Ad Hoc network,designs two simulation schemes which are used for three routing protocols’ simulation by NS2.The packet delivery ratio and average end-to-end delay are analyzed,the results indicate that AODV protocol has the outstanding integrated performance and is more fit for the network in which mobile nodes move more quickly and network topology changes more frequently.更多还原
