Abstract: In AODV routing protocol，an intermediate node can reply a RREQ when it has a route with a sequence number that is greater than or equal to that contained in the RREQ，no matter how many packets are waiting to send in it.This routes’ performance may degrade because local congestions may incur on those nodes with the increase of offered load.To solve this problem，a multi-path routing methods MP-AODV has been optimized on the basis of AODV.And reduce link invalidation rate by using initiative routing mechanism.The simulation results show that the protocol is improved compared to the original protocol.End-to-end delay and packet loss rate are all reduced，and the transmission efficiency is improved at the same time.

摘要： 为了减少建立路由所产生的延时，AODV路由协议允许拥有积极路由的中间节点响应路由请求，而不考虑该节点当时的负荷，这样虽然快速地建立了路由，但并不一定能有效地传输数据。针对这一问题，在AODV的基础上对一种多路径路由方法MP-AODV进行了优化。并结合主动式路由机制，进一步降低了链路失效。仿真结果表明改进的协议和原协议相比，降低了端到端的延时和丢包率，提高了传输效率。
