摘要
利用移动自组网中节点的局部冗余性进行链路修复,提出一种新的基于监听的AODV路由协议。节点通过监听邻居节点数据包的发送,获得本地的局部拓扑信息,并在满足备份链路条件的情况下,通知源节点成为其备份链路。当发生链路断开时,直接用路由表中的备份链路进行修复,而不需要广播RREQ分组。NS2仿真结果表明,在不同的动态场景中,算法均表现出良好的性能。
This paper presents a new AODV-ALR routing protocol which makes used of node redundance in MANET to repair link-break.Nodes get local topology by overhearing the data packets transmission of their neighbours,and inform the source node if it could become the backup next-hop node.When link breaks node need not broadcast RREQ.It switches to the backup next-hop node to communication.The results of NS2 simulation show that the algorithm performs well in different dynamic scenarios.
