摘要
路由问题一直是移动Ad Hoc网络(MANET)研究中的难点和重要问题。按需路由协议是当前移动Ad Hoc网络的主流路由协议。文中通过对AODV和DSR两种典型的按需路由协议的分析与比较,提出了一种利用DSR的路径收集机制来改进和提高AODV路由协议性能的方法。通过NS2仿真实验表明,该方法能有效减少路由请求的数量,从而降低路由的开销,提高分组发送的成功率,减少端对端的延时。
Route is a hard and important issue in the research field of MANET, and on-demand protocols are dominating protocols in MANET. With the analysis and comparison on AODV and DSR, a perfarmance improvement of AODV is proposed by utilizing the path learning mechanism of DSR. The NS2 simulation results show that, this means can achieve more effective performance than AODV in reduction of the numbers of route request, thus cutting down the routing overhead, raising the ratio of packet delivery and shortening the end to end delay.
