摘　　要：在Ad hoc网络中,为了平衡能耗与鲁棒性,结合基于树和基于网格的多播协议的特点,给出了一个新的多播路由协议,基于Poweraware优化的备用路径的多播协议(poweraware-backuptreemulticast,Pa-BTM)。该协议采用主树和备用树相结合使用的方法,当主树损坏后立即采用备用树进行工作,提高了鲁棒性,同时基于树的结构也减少了能量的消耗。最后,使用仿真工具GloMoSim对MAODV,ODMRP及Pa-BTM模拟仿真。仿真结果表明,该协议在包分发率和能量效能等性能上有所改善,可以较好地提高网络生存时间。In Ad hoc networks, in order to balance energy consumption and robustness, a new multicast routing protocol, called alternative backup tree multicast routing protocol （Pa-BTM） is proposed based on characteristics of tree-based multicast protocol and mesh-based multicast protocol. The routing protocol use two trees called primary tree and backup tree, when the primary tree is broken immediately use backup tree to instead of the responsibilities of the primary tree. The robustness is improved, and the tree-based structure reduce the energy consumption. Finally, the simulation tool GloMoSim is used to simulate our proposed protocol. The results of simulation show that the performance of the proposed algorithm improves the load balance, packet deliverd ratio and the life time of the network.
