说明：  ：Ad HOC网络是随着无线通信技术的快速发展而出现的一种新型网络， 网络层的路由协议对于Ad HOC网络来说尤为 重要。首先阐述了Ad hoc 网络的概念和特点，分析了自组网路由协议的有关情况。重点研究了按需路由协议中的AODV协 议及其中断链恢复的改进，结果表明在数据传输延迟和路由开销方面，采用改进的本地修复方法都可以使性能获得一定程 度的提高
(Abstract：The Ad hoc network is a kind of new network that appears with the development of wireless communication technology，the muting protocol in network layer is very important to Ad hoc network． The concept and characteristics of Ad hoc network was introduced firstly， and the muting protocol was analyzed． Th e AODV protocol Was mainly discussed an d improved in restore of interrupt link．It is proved that in transmission delay and muting consuming improved local restore method could advance the performance．)
