摘　　要：为了提高无线传感器网络在数据采集过程中节点能耗的均衡性,延长网络的生命周期,提出一种基于能量平衡的动态分簇算法。在簇的建立阶段,该算法考虑节点基于距离与剩余能量的竞争函数构建能量平衡的分簇,并将各簇内节点数据依据竞争函数进行分级处理。为避免节点集中死亡,在簇的运行过程中,周期性检查各簇的能量情况,并动态调整分簇以维持整个网络能量的平衡状态。对比LEACH、HMDC算法,仿真结果显示,该算法使得节点能耗更加均衡,能量使用效率得到提高,网络生命周期得到延长。In order to improve energy consumption balance and extend network lifetime during the period of data gathering in wireless sensor networks,it proposes an energy balanced dynamic clustering algorithm.At the stage of cluster establishment,the algorithm considers the competing function of distance and residual energy to construct clusters with energy balance,and classifies the data of nodes in each cluster according to the competing function.In order to avoid many dead nodes in one cluster,the total energy of each cluster is checked periodically during the operation of the cluster,and the cluster is dynamically adjusted to maintain energy balance of the sensor network.Compared with LEACH and HMDC algorithms,simulation results show that the proposed algorithm makes the energy consumption in the sensor network be more balanced,the energy consumption efficiency be improved,and the network lifetime be extended.
