  We consider the problem of moving target tracking in Wireless Sensor Network (WSN). In WSN which consists of great number of sensors, their capability is limited to quite low performance because of their low cost. Therefore, it is important to satisfy flowing two requirements for the target tracking: (I) Multi-point surveillance with appropriate number of sensors that depends on the characteristics of applications and user requirement, (II)Dynamic switching and quick decision of monitoring sensors in response to the movement of target. Therefore, we propose multi-point surveillance scheme of moving target and evaluate its performance. Through the simulation experiments, we demonstrate that our proposed scheme can quickly and appropriately decide the monitoring sensors with low communication overhead in response to the movement of target, thereby maintaining high tracking probability even for the high speed target.
