摘　　要：文章分析了无线传感器网络的特点以及能量消耗的问题,提出了一种基于最优多播树的低耗路由算法。通过将网络划分成若干的簇,在簇内采用基于能耗优先的簇首节点动态生成算法,同时构造最优多播树作为数据传输的路由,并在中间节点进行数据融合以减少传输的数据量。理论分析和仿真结果表明,此算法具有较好的性能,可以有效地降低节点能耗,延长网络寿命。This paper analyzes the energy expenditure problem of the wireless sensor network and proposes an energy efficient routing algorithm based on optimal multicast tree.In this algorithm,the WSN is divided into several areas.Each node takes turn becoming the cluster head through a dynamic algorithm based on energy expenditure.It constructs an optimal multicast tree to transmit data and uses data-fusion to fuse the redundant data.Theoretical analysis and simulation results indicate that the new algorithm has better performance which can effectively save energy and prolong the network's lifetime.
