无线传感网能量监测方法研究

Research on Energy Monitoring Method for Wireless Sensing Network

对无线传感网的能量消耗情况进行了研究。提出两种对网络中节点剩余能量进行监控的方法。一种方法基于软件,靠读取最大接收能量指示值判断节点能量的消耗,只适用于节点位置固定情况;另一种方法基于硬件,利用AD采集本地电源供电电压信息,判断节点能量消耗,普遍使用于各种路由拓扑场合。通过硬件实验,证实了这两种方法都能给出整个网络的能量消耗量,并在能量不足时给出提示。

The energy consumption of wireless sensing network is studied. Two of the methods for monitoring and controlling the residual energy in network node are proposed. One of the methods is based on software. By reading maximum receiving energy indication value to judge the consumption of energy on the node, this method is only suitable for the node with fixed position. Another method is based on hardware. By adopting AD collecting local power supply voltage information to judge energy consumption, this method is widely used in various routes topologies. Through hardware tests, it is proved that these two methods can find out the e,ergy consumption of entire network, and alert operators when energy is insufficient.
