摘要： 介绍自组网和路由协议，对AODV中的链路修复问题进行分析，提出优化方案并给出具体实现。优化方案使用overhearing技术侦听邻节点路由信息，通过广播数据包来完成路由查找和修复的任务。通过模拟试验发现，与传统方法相比，该方案可以减少重路由带来的时延，在一定程度减少了路由开销。

Abstract: This paper introduces Ad Hoc networks and the routing protocols, presents the analysis and simulations of the link repair of the Ad Hoc On-demand Distance Vector(AODV) protocol and provides a new scheme to improve the performance of link repair. By overhearing the routing information, the new scheme uses broadcasting to repair broken routes. Simulations results indicate that the improvement in less delay and routing overhead while compared with the traditional method to some extent.

Key words: Ad Hoc, Ad Hoc On-demand Distance Vector(AODV), local repair, network simulation
