双层协作的无线传感器网络目标跟踪方法

Double-circle Cooperative Target Tracking Method in Wireless Sensor Network

通过在无线传感器网络中引入双层监测机制,提出一种基于象限定位的目标跟踪方法。该方法依据位置关系选取相关性高的内外层节点,利用外层节点的快速侦测和内层节点的准确定位对移动目标进行定位跟踪,同时向汇聚节点快速上传移动目标轨迹。理论分析和实验结果表明,该方法可以降低无线传感器网络功耗,提高目标定位精度。

By introducing the double-circle monitoring mechanism into Wireless Sensor Network（WSN）,this paper proposes a target tracking method based on quadrant location.It selects the high-relative nodes based on the relation of the nodes positions,locates the mobile targets which are rapidly detected by the outer circle and accurately located by the inner circle,and uploads the mobile target track to the sink simultaneously.Theoretical analysis and experimental results show that the method can reduces the power consumption of WSN and increases the locating precision.
