摘要
针对基于无线传感器网络的目标追踪应用提出了一种节点唤醒策略。对于目标是否进入网络监测范围,提出了巡逻监测法。对于已经进入监测范围的目标,提出了基于传感器节点自身的唤醒方法。理论分析与仿真表明该方法相对基于目标位置预估计的节点唤醒方法,提高了节点唤醒效率,减少了能量消耗。
The method of node awakening on target tracking the web area inspection, the patrol means is put forward, and itself is proposed. Theoretical analysis simulation shows that application based on WSN has been proposed. Against the technique of node awakening based on sensor node this method is efficiency improved and consumes less energy.
