摘要
本文利用链路和节点发送缓存的状态信息对DSR协议进行优化和改进,提出了一种Performance-DSR(PDSR)协议。文中对PDSR协议的路由更新和路由选择机制进行了介绍,并对PDSR协议和DSR协议在节点不同移动速度下的性能进行了分析比较,结果表明PDSR协议比DSR协议更能适应网络拓扑变化快的MANET网络。
A Performance-Dynamic Source Routing protocol （PDSR） is proposed in this paper, which uses link state information and node state information to improve on the performance of DSR.The route-update metric and route-select metric of PDSR are described in this paper, and the performance of PDSR is shown in simulations. The simulation results indicate that PDSR has better performance than DSR in high dynamic environments.
