摘　　要：对DSR路由协议进行分析,针对路由维护的不足,提出了一种新的本地修复算法.充分利用邻居节点缓存的信息,将修复范围限制在一跳或两跳内,减少了修复时间和降低了路由维护开销,提高了处理失效链路的能力.仿真表明,新的本地修复算法提高了数据递交率,网络吞吐量,降低了控制开销和路由发现频率.According to the DSR protocol maintenance s weakness,a new idea about local recovery of route was proposed which made full use of neighbor nodes cache,limited the scope of repair in one or two hops,reduced repair time,decreased the routing maintenance expense and increased the capability to handle the link failure.Simulation shows that the new algorithm increases the packet delivery rate,network throughput,reduces control overhead and routing discovery frequency.
