Abstract

This paper provides a scheme to improve the read efficiency of anti-collision algorithm for the EPCglobal UHF Class-1 Generation-2 RFID standard. In this standard, dynamic frame slotted ALOHA is specified to solve the anticollision problem. Also, the Q-algorithm with a key parameter C is adopted to dynamically adjust the frame sizes. In the paper, we propose a new method, named early frame length adjustment, to adaptively adjust the Q-value to increase the read speed. Our method can achieve the read speed of up to 400 tags per second and reach the read throughput close to the theoretical value. The results indicate our method outperforms the original Q-algorithm. The read performance can be suitable for reading objects in logistics management.
