摘　　要：为了延长网络生命周期,解决高压输电监测的无线传感器网络中节点能量受限问题,结合应用背景的实际特点,提出一种基于节点动态聚类的功率控制算法。该算法以高压输电监测的网络架构为基础,分析传感器节点间的空间几何位置关系,综合考虑空间几何信息与节点剩余能量,利用聚类分析方法对网络内具有相似性的节点进行动态聚类,使数据转发在类区域代表节点之间传递。同时,采用可变的功率调制技术进行数据传输。仿真结果表明,该算法能够有效地降低网络能量消耗,并延长网络的生命周期。A power control algorithm based on node dynamic clustering is proposed, in order to prolong the network lifetime and solve the problem of limited node energy in wireless sensor networks of high voltage power transmission monitoring. The algorithm is based on the transmission monitoring network architecture. By analyzing the geographical relationship between sensor nodes, considering the residual energy of geographical information and nodes comprehensively, and using cluster analysis method to dynamically cluster nodes that have similarity nature, all packets can forward from one representative node to another node during transmission phase. Meantime, variable-power modulation technology is used for packet transmission. Simulation results show that the algorithm is effective to reduce network energy consumption, and prolong the lifetime of the network.
