摘　　要：MANET网络中的路由协议大多是采用洪泛的方式进行路由查找。如AODV,在节点密度较大的情况下容易造成网络堵塞;当路径发生断裂时,也是以广播RREQ封包来重建路由,修复速度较慢,同时也会产生更多的网络控制封包。因此在AODV的基础上,以多点中继的广播机制来减少广播封包,并利用2跳的邻居表进行路径的局部修复来设计新的路由机制。模拟实验证明该协议能够减少网络中的封包,快速有效地修复路由,提高网络的性能。Most of the routing protocols of MANET use flooding, such as AODV, in the route lookup, but this may lead to the network congestion in case of high node density. AODV will rebroadcast the request packet to re- build route when the path is broken, which is relatively slow and will generate more control packets. A new routing mechanism is proposed on the basis of AOVD to reduce broadcast packet through the multipoint relay broadcast scheme and to repair route by using an additional 2-hop neighbor table. It has been proved in the simulation experi- ments that this protocol can reduce the number of packets and effectively repair the route, so as to improve the net- work performance.
