摘　　要：在移动自组网接入Internet的过程中,为适应节点高速移动导致网络拓扑频繁更新的特性,在混合式路由发现中引入自适应机制,从网关通告跳数的合理范围、广播风暴的避免、各节点和网关负载的动态变化等方面进行自适应性优化。以AODV路由协议为基础,改进网关发现算法的自适应机制,在NS2平台进行仿真,实现移动自组网与有线网络的互联,且其接入性能有一定程度优化。For the Internet connectivity ol MANET , in order to meet the frequent updates ol networktopology caused by high speed mobile nodes,this paper introduces the adaptive mechanism in the hybridrouting discovery,to design an adaptive optimization from aspects ol the reasonable range ol TTL , theavoid ol broadcast storm and the dynamic load ol each node and gateway. Based on the AODV protocol,the gateway access can improve adaptively, through the simulation ol NS 2 , MAN E T connects withInternet successlully,and its access gateway performance has a certain degree ol optimization.
