アブストラクト
  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 decisionmaking 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.
