| 摘 要： | 移动自组网多跳、动态拓扑的特性,使得路由信息易老化,源节点在路由失败后不能及时启动路由发现,造成TCP有效吞吐率随移动速度增加而下降。在DSR路由协议的基础上,提出一种新的基于接收方参与启动路由发现的新路由协议RP DSR,它通过接收方的ACK确认包启动路由发现,主动为发送方提供最新的路由信息,从而提高了自组网的TCP的性能。仿真结果表明,在节点快速移动环境中,RP DSR协议的TCP性能明显优于DSR协议。

| Abstract: | In wireless mobile ad hoc environment, the characteristics of multi-hopping and dynamic topology make route information stale quickly, and the sender cannot activate route request in time when route fails. All these make the throughput of TCP over DSR degrades when mobile nodes move fast. RP-DSR was proposed based on DSR, in which the receiver participated in route discovery. The simulation results show that RP-DSR protocol can get more satisfying performance than DSR in the status of fast and dynamic topology. |
