Abstract

Recently, the UHF-band RFID (Radio Frequency IDentification) technology that has been spotlighted. A RFID system is comprised of readers and tags. In the RFID environment that multiple readers exist, the mutual interference causes collision problems. This paper proposes the centralized arbitration scheme for avoiding the collision problems between multiple readers. By the centralized arbitration scheme, readers that want to communicate with tags are allotted to operate at different times. This paper presents the algorithm, modeling and simulation, of the centralized arbitration scheme.
