| 摘 要： | 介绍了自组网和路由协议,对AODV路由协议中的断链问题进行了分析和仿真,提出了对其进行优化的方案并给出具体实现。优化方案使用了本地的反向路由重建方法,通过广播一个链路修复消息同时完成了路由查找和路由建立的任务。与传统的路由重建方式相比,可以节省在重建路由时引入的时延,并在一定程度上减少了路由重建的额外开销,以更好地适应自组网的应用环境。

| Abstract: | Because of the flexibility and convenience it can provide us, the mobile ad-hoc network becomes a very hot research topic presently. There are many related articles presented on various journals in this area, especially concentrated on the ad-hoc routing protocols. But, the solutions provided still have more or less defects. Firstly this article introduces the special characters of ad-hoc network and the existing routing protocols. Then analysis and simulation of the link break of ad-hoc on-demand distance vector in ad hoc networks are presented and a new mechanism to improve the performance of link repair is provided. The simulation results indicate that the improved method results in less delay and routing overhead while reconstructing route compared to the traditional method to some extent. |
