Homogeneous RFID 시스템에서 다수의 리더 충돌 방지 기법

Typical RFID readers anti-collision protocol is Low-Energy Localized Clustering for RFID Networks (LLCR). LLCR is the protocol that minimizes the interference by regulating the RFID reader’s cluster radius, but it is difficult in many readers system. In this paper, we propose the protocol that three neighboring readers and another three neighboring readers at a long distance are operated stepwise for homogeneous RFID system.
