摘　　要：Ad hoc通信网中业务总负载的增大会导致按需多播路由协议(ODMRP)的网络吞吐率下降,为此,提出一种改进的ODMRP。引入负载均衡算法,根据站点当前的负载大小决定是否接收JOIN-TABLE信令作为转发组成员,并选择负载较轻的节点完成多播数据的转发,从而缓解网络拥塞,充分利用网络资源。仿真结果表明,在高负载情况下,改进的ODMRP可有效提高网络吞吐率,减小数据丢失率。Considering depressed network throughput performance of On-demand Multicast Routing Protocol（ODMRP） with increased load in Ad hoc network, an improved ODMRP is presented. It brings in load balancing algorithm, which accepts or discards a JOIN-TABLE based on the recent load of a node, and a node with light load becomes a transmit node to ease network congestion and make full use of network resource. Simulation results show that the improved ODMRP can increase network throughput and decrease data loss rate under heavy load.
