摘要
移动A d hoc网络(M ANET)是一种多跳无线网络,网络中的节点互相通信而不依赖于预先架设的固定基础设施,它在军用和紧急救援等特殊环境的应用前景非常广阔,其中多播路由技术是当前研究的热点.文中在M AODV的基础上,提出了基于G roup H e llo消息机制、路由发现和路由维护的M AODV多播路由协议的改进方案,并进行了仿真试验,结果表明改进后的协议减少了开销、降低了时延,在高负载的网络中尤为明显.
Mobile ad-hoc network is a multihop wireless network,where nodes communicate with each other without any pre-deployed infrastructure,and will be widely used in critical environment such as military or civilian emergency operations. The multicast routing technology of MANETs is a hot point of study. This paper presents an MAODV-based improvement protocol with the group hello message mechanisis,routing discorvery and routing maintaining. The simulation shows that the improvement protocol could reduce the routing overhead and delay in high load networks.
