| 摘 要： | 在ODMRP协议中，由于采用周期性地广播Join-Query包来更新成员信息和路由信息，因此网络中流动着大量平凡的Join-Query控制包，造成网络开销增大，网络拥塞。采用能量驱动的概率转发的方法，根据每个节点的能量资源信息为每个节点设置相应的转发投递概率，抑制网络中的Join-Query控制包。模拟结果显示，能量驱动的MANET概率组播路由协议(p-ODMRP)在投递率满足需求的情况下，网络的控制开销减小20%左右，增加了网络寿命，协议的综合性能有明显提高。

| Abstract: | In on-demand multicast routing protocol(ODMRP),as it updates the member and routing information by periodically broadcasting the Join-Query packets,there are many ordinary Join-Query packets in the network,causing the increase of network overhead and network jam.It uses a probabilistic routing scheme driven by energy.It sets the probability of forwarding for every node in the network according to their information of energy resource and exploits this probabilistic forwarding mechanism to reduce the number of Join-Query packets in the network.Simulation results show that the energy-driven probabilistic multicast routing protocol for MANET(p-ODMRP)reduces the overhead of network by 20%and increases the lifetime of the network when the delivering ratio meets certain constraints. |
