A Protocol Minimizing Missing Tags in a Moving RFID Tag Environment
Keywords:
Anti-collision, DFSA, missing tag, moving tag, RFID.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).
