Abstract
Mobile RFID, the technology of a cellular phone equipped with a RFID reader, allows users to read RFID tags anywhere. However, signals from more than two readers can interfere with one another, i.e., reader collision problem; reliable tag reading is necessary. This paper proposes GENTLE protocol to use beacon messages and multi-channel for increasing throughput. GENTLE protocol can also put tag ID information into the beacon message and share it among close readers. In addition, we suggest LSWBT protocol that reduces reader collision without beacon messages. Simulation results show that GENTLE and LSWBT protocols outperform existing reader anti-collision protocols.
