Abstract: 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.
