基于指数平均模型的无线传感器网络动态功耗管理
Dynamic Power Management Based on Exponential Average Model for WSN
摘要
Abstract
The key factor hindering the development of Wireless sensor network( WSN) is the energy. In order to re-duce the power consumption and extend the node life time of WSN,an effective method of dynamic power manage-ment strategy based on exponential average model is proposed in this paper. The strategy uses historical idle time to make predictions about the future idle time,and the prediction result will be the basis to decide whether the node is converted into a low power state or not. Facing the burst situations, theoretical analysis and experimental results show that the proposed algorithm can adjust quickly adaptive to improve the accuracy of forecasts and reduce the power consumption of the system.关键词
