A Protocol Minimizing Missing Tags in a Moving RFID Tag Environment

Chul Wan Park, Ji Hyoung Ahn, and Tae-Jin Lee
Abstract— A collision caused by transmitting several tag IDs simultaneously reduces throughput and increases identification delay in Radio Frequency IDentification (RFID) systems. In a moving tag environment, frequent collisions may lead to a situation wherein unidentified tags may leave the reader's identification range. These missing tags lower the identification rate of tags in a moving tag environment. In this paper, we propose a new method to minimize the missing tags in a moving tag environment to increase the identification rate. The proposed method, ALOHA-based Minimizing the Missing Tags (AMMT), is designed to improve the identification rate by minimizing the missing tags. Simulation results show that AMMT provides better identification rate compared to Dynamic Framed Slotted ALOHA (DFSA).

Index Terms— Anti-collision, DFSA, missing tag, moving tag, RFID.
