摘　　要：基于场景用仿真方法研究了3种适用于分布式无线网络的路由协议及其网络性能.仿真结果表明,当通信半径一定时,3种路由协议的网络性能均随着网络中节点运动速度的提高而变差;当节点运动速度一定时,3种路由协议的网络性能均随着节点通信半径的增加而变好;同等条件下,Ad hoc按需距离矢量路由协议的端到端通过量高于动态源路由协议和目标序列距离矢量路由协议,分组丢失率低于动态源路由协议和目标序列距离矢量路由协议,而目标序列距离矢量路由协议的平均分组传输时延保持最低.A comparison of three routing protocols developed for mobile ad hoc networks is made. The protocols are: Dynamic Source Routing(DSR), Destination Sequenced Distance Vector (DSDV) and Ad-hoc On demand Distance Vector(AODV). Extensive simulations are made on a scenario where nodes move randomly. The simulation results show that all the three protocols perform worse when the nodes move faster with a specific communication radius, and perform better when the communication radius becomes larger with the specific nodes speed. Furthermore, the results show that the AODV protocol has a higher end-to-end throughput and a smaller packet dropping probability than DSR and DSDV, with DSDV having the smallest packet transmission delay under the same conditions.
