分析研究AODV协议本地修复算法的特点，并对其进行改进，形成了改进的AODV路由协议本地修复算法-A new idea about local repair is used to improve the AODV and formed the Improved AODV algorithm.Otherwise，a new approach is proposed for flooding limit.The approach is implemented by using cross-layer

(AODV creates and uses two phases (1) Discovery of route and (2) Maintenance of route. Protocol uses Request (RREQ)of route, Reply (RREP) of route, Discovery of route and Error of route (RERR) control message in Maintenance of route .The beginning
