摘　　要：ODMRP协议是无线自组网环境下的一种按需式多播路由协议。提出了一种对该协议的改进,即ODC-ODMRP路由协议。协议继承了ODMRP协议对拓扑频繁变化的良好适应性,并采用按需式分簇机制(ODC),有效减少了泛洪带来的控制开销,提高了网络的路由效率。实验结果表明,该算法具有路由收敛速度快、泛洪效率高、控制开销小等特点。ODMRP protocol is an on-demand multicast routing protocol in Ad hoc network. This paper presented the On- Demand Multicast Routing Protocol with On-Demand Clustering. ODC-ODMRP introduces on-demand technique to reduce the flooding control overhead and improves the performance of networks. At the same time, ODC-ODMRP reserves other key merits of ODMRP such as high performance in conditions with frequently changing topology. Analysis and simulation show that the protocol is characterized with its quick convergence and low maintenance costs of routing, robust and efficient flooding platform over dense, large mobile networks.
