摘要: 无线传感器网络中各节点能耗不均衡严重影响了网络的生命周期。首先通过理论分析得出了圆形区域网络的数据量转发和能量消耗特性,其次阐述了如何选择最优的发射功率使得网络寿命最长,最后为进一步降低网络能耗,提出了一种有效的数据量转移的能量均衡策略,数值仿真结果证明该策略可以有效降低整网能量消耗,延长网络生存周期。

Abstract: In the wireless sensor networks,unbalanced energy consumption has a strong impact on the network lifetime.Characteristics of data switching and the energy consumption in circular region network are analyzed firstly.And then how to choose the optimal transmitting power to maximize the network lifetime is elaborated.Finally,the strategy is proposed about energy balance based on data transfer.Numerical simulation results show that the strategy can reduce the entire network energy consumption effectively and extend the network life cycle.
