We consider the problem of moving target tracking in a wireless sensor network (WSN) in which the capability of each sensor has relatively limited performance enabling us to construct large-scale systems/networks at reduced cost. In order to achieve moving target tracking with high resolution, the following two requirements must be satisfied: (I) Multipoint surveillance with the appropriate number of sensors, which depends on the characteristics of the applications and user requirements, and (II) Dynamic switching and quick decision-making of monitoring sensors in response to the movement of the target. In the present paper, we propose a simple and robust multi-point surveillance scheme for moving targets in WSNs. Through simulation experiments, we demonstrate that the proposed scheme can quickly and precisely assign monitoring sensors on a WSN of any density with low power consumption in response to the movement of the target, thereby maintaining high tracking probability even for high-speed targets.
