针对24台移动终端在无线自组织网络中的联网通信需求,需要选择一种能够适应Ad Hoc网络拓扑结构不断变化的路由协议。文章对Ad Hoc网络的路由协议进行了分类和比较,并通过GloMoSim仿真平台,结合具体的网络仿真场景,着重对Ad Hoc网络中的AODV和DSR两种按需路由协议进行性能仿真测试,比较不同移动速度下两种协议的平均端到端时延、分组投递率和吞吐量性能优劣。实验表明,节点在GloMoSim平台中成功实现了通信互联,无论节点在静止状态还是高速移动情况下,AODV的性能都要优于DSR协议。

According to the communication requirements of twenty-four mobile terminals in the wireless Ad Hoc network,it's necessary to select a routing protocol adapting to constantly changing of Ad Hoc network topology. In this paper,Ad Hoc network routing protocols are classified and compared,and through GloMoSim simulation platform,focus on testing the performance of two on-demand routing protocols ( AODV and DSR) of the Ad Hoc network with specific network simulation scenarios,to compare the performance difference in the average end-to-end delay,packet delivery ratio and throughput of the two protocols in different speed. The simulation results show that these nodes have successfully achieved communication interconnection in the GloMoSim platform,and the performance of AODV is better than DSR either in static state or in high-speed mobile case.
