摘　　要：针对Ad hoc网络中两种路由协议AODV和DSR,用NS2网络环境模拟器对分组投递率和归一化路由开销两个性能指标进行了仿真,分析和对比这两种路由协议在不同的通信模型和移动模型条件下的性能表现。NS2仿真结果表明,两种路由协议AODV和DSR,节点越大,分组投递率越高。节点数大的,路由开销较为平稳。在艰难的作战环境下,AODV协议表现得更加有效,而在相对平稳的环境下,DSR协议表现得更好。Aiming at two kinds of routing protocols AODV and DSR in Ad hoc networks, two characteristics of packet delivery ratio and normalized routing overhead are simulated with NS2 network environment simulator. The performance of two kinds of routing protocols are analyzed and compared with each other in different communication models and moving models. NS2 simulation results show that the greater the node, the higher the packet delivery ratio and the more stable routing overhead for two kinds of routing protocol AODV and DSR. In difficult environments, AODV protocol is more effective in performance, and in a relatively stable environments, the DSR protocol is better.
