提出了一种能量均衡的无线传感器网络组播路由算法EBMR。EMBR算法的目标是提高组播的能量效率和延长网络生存时间。为了实现这一目标，分析了无线传感器网络的能量消耗模型，研究了一种能量受限的组播转发节点选择方法。然后讨论了EBMR算法的框架。仿真结果表明，EBMR算法能够均匀地降低整个网络的能耗。与最短路径树（SPT）组播路由算法相比，EMBR算法可以延长网络的生存时间。
An energy-balanced multicast routing algorithm EBMR in wireless sensor networks (WSNs) is proposed. The objective of EMBR algorithm is to improve the energy efficiency and extend the network lifetime in multicast. To achieve this goal, the energy consumption model in WSNs is analyzed and an energy-constrained metric for multicast forwarder selecting is studied. Then the framework of EBMR algorithm is discussed. Simulation results show that EBMR algorithm is able to reduce energy consumption of the whole network evenly. Compared with shortest path tree (SPT) multicast routing algorithm, EMBR algorithm will extend the network lifetime.
