摘要: 针对无线传感器网络能量分布不均匀的特点,提出一种基于能量平衡的节能机制。在随机性睡眠节点调度机制基础上,引入了反映网络能量状态的概念——能量平衡度。依据能量平衡度来修正节点睡眠概率使网络能量平衡。仿真结果显示机制可以保证较高覆盖率下并使网络能量平衡。

Abstract: The characteristics of energy uneven of wireless sensor networks are considered,a balanced-energy energy-efficient mechanism is proposed.Based on the stochastic sleeping node-scheduling scheme,energy balance level that reflect state of energy of network is introduced.The mechanism depends on energy balance level change node’s sleeping probability to balance energy consumption of network.The simulation result shows the mechanism can guarantee a high coverage rate and maintaining balanced-energy.
