摘　　要：Ad hoc网络是由一组带有无线收发装置的移动终端组成的一个多跳的临时性自治系统。MAODV协议是MANET环境下的一种按需组播路由协议。提出了一种基于链路失效预测机制的MAODV协议的改进协议。采用该协议,时延略有增加,但分组投递率极大提高了,在整体上提高了网络的性能。通过仿真实验验证了协议的改进效果。Ad hoc Network is a multi-hop provisional autonomy system made up of a group of portable terminals with wireless transmitter. MAODV protocol is an on-demand multicast routing protocol in MANET. This paper presents an improvement of the MAODV based on link failure forecast. The improved protocol introduces link failure forecast technique to increase the delivery ratio, thus improves the performance of the networks with a small increase of protocol delay. The performance of the protocol with MAODV for MANET is evaluated via extensive simulation.
