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。
Ad hoc通信網中業務總負載的增大會導緻按需多播路由協議(ODMRP)的網絡吞吐率下降,為此,提齣一種改進的ODMRP。引入負載均衡算法,根據站點噹前的負載大小決定是否接收JOIN-TABLE信令作為轉髮組成員,併選擇負載較輕的節點完成多播數據的轉髮,從而緩解網絡擁塞,充分利用網絡資源。倣真結果錶明,在高負載情況下,改進的ODMRP可有效提高網絡吞吐率,減小數據丟失率。

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.
