Abstract:

Radio frequency identification (RFID) systems have been widely deployed for inventory management, personal identification, and asset tracking. In such environments, RFID tags frequently move in and out of a reader's interrogation zone. Consequently, it is necessary for a reader to keep track of all tags in its interrogation zone in a periodic manner. This requirement not only increases workload of a reader but also generates large amount of traffic from a reader to a management server. In this paper, we propose a selective tag identification protocol which has two sub-frames: an identification frame and an access frame. The proposed protocol improves RFID tag identification performance by introducing a frame counter that enables readers to discriminate newly arriving tags and leaving tags. In addition, simulation results show that the proposed protocol reduces the amount of traffic from a reader to a management server by updating only the changes in tag population.
