摘　　要：无线传感器网络由于多跳通信和多对一的数据流导致能量消耗分布极不均衡而产生能量空洞,大大缩短了网络寿命,浪费了能量.文章探讨了利用功率控制策略平衡无线传感器网络节点能耗,分析了在节点均匀分布的圆形网络中,采用不等宽圆环划分网络,调节节点发射半径的功率控制策略实现网络中节点能耗的均衡.仿真分析显示网络生命周期结束时,处于网络中内部节点同时耗尽了自身的能量.As a result of multi-hop communications and many-to-one data stream led to energy consumption extremely uneven, energy holes do not avoid in wireless sensor networks. Because of energy holes, the life of a network is greatly shortened. In this paper, the theoretical aspects of the scheme of energy balance are investigated based on power control in wireless sensor networks, and it is analyzed that in a circular network with uniform node distribution, the use of wide-ranging network division ring and adjusting the radius of the launch of the power node control strategy can achieve the network node of a balanced energy consumption. Simulation analysis shows that when the life cycle of the network ends, the internal node in the network consumes its energy depletion at the same time.
