摘　　要：为了延长无线传感器网络的生命周期,提出了一种基于动态分簇的集中式数据存储算法。根据节点的剩余能量选取簇头,节点依据距离簇头远近和存储代价初步成簇,簇头通过衡量簇规模来动态调整簇成员节点的退出或加入,改善簇规模过大或过小的情况,动态分簇成功后进入网络数据的采集和存储阶段。仿真结果表明,该算法能够节省能量,更好地均衡负载,延长网络的生命周期。To improve the lifetime of wireless sensor networks,a centralized data storage algorithm based on dynamic clustering is proposed.Cluster heads are selected according to the residual energy of the nodes.The node chooses to join the cluster,which depends on the distance from the cluster head and the storage cost.The cluster head dynamically makes the cluster member nodes exit or join by measuring the cluster size,so as to improve the situation that the cluster size is too large or too small.After successful dynamic clustering,the network enters the stage of data collection and storage.Simulation results show the proposed algorithm can save energy consumption,balance the load and prolong the network lifetime.
