In this paper, we present a RFID reader scheduling strategy for an effective identification by varying coverage through power control. A RFID reader is incorporated into a surveillance system which tracks objects with visual sensors. A required separation between objects is defined to avoid group identification with multiple objects. In order to reduce the power consumption of a RFID reader, the power cost is simply modeled with object positions to determine the activation time and the range of a RFID reader. The power cost model also considers the effect of added power consumption establishing group identification. A RFID reader is activated when the estimated power cost for the current sampling time is smaller than the estimated power cost for the next sampling time. The simulation results demonstrate that the proposed method reduces the power consumption with the effective object identification.
