基于NS2的无线自组织网络路由协议仿真

Simulation of Ad-hoc Routing Protocols Based on NS2

在无线自组织网络中,由于节点移动,网络拓扑结构变化频繁,所以路由协议的选择一直都是关键问题。该文采用NS2软件对两种主要的协议:动态源路由协议(DSR)和自组网按需距离矢量路由协议(AODV)进行了仿真。并且通过端到端延时、路由开销和分组投递率三种参数在不同条件下的数据对两种协议进行了评估。实验结果表明没有一种协议能够完全适用于自组网,对于特殊环境选择不同协议以满足需要。

In ad hoc networks, due to the mobility of nodes and frequent changes of network topology,the choice of routing protocol has always been the key issue.In this paper,two main protocols：Dynamic Source Routing protocol（DSR） and ad hoc networks on-demand distance vector routing protocol（AODV） are sim- ulated by using NS2 software.And evaluated the two protocols through the three parameters：end-to-end delay,routing load and packet delivery ratio that under different conditions.The results show that there is no protocol can fully applicable to ad hoc network,we should select different protocol to meet the special en- vironment.
