一种基于冗余度的无线传感器网络节能策略

在无线传感器网络中,传感节点由于采用电池供电,因此寿命有限。如何有效节省传感器节点的能量,延长网络的使用寿命,一直是广泛研究的焦点。文章提出一种适用于高冗余度布置的无线传感器网络结构中,节省传感器节点能量消耗的方法-接续调度法。该方法通过协调点对小区域内节点的调度,使区域内节点依次分时段工作。通过这种接续调度,避免了节点间的冲突和串扰,达到延长整体网络寿命的效果。

An Energy Saving Strategy based on redundancyratefor Wireless Sensor Networks

In wireless sensor networks(WSNs),the lifetime of a sensor node is usually limited because of battery power.How to save the sensor node energy effectively and prolong the network lifetime have been widely studied for a long time.This paper proposes a novel scheduling approach,named alternately scheduling method,which is suitable for WSNs with redundant deployment in a high density to reduce the energy consumption of sensor nodes.The proposed scheme schedules sensor nodes inside a small area to work in diffe...
