Abstract
In order to further improve identification efficiency of tag anti-collision algorithm in RFID system, we analyze the performance of the frame-slot ALOHA anti-collision algorithm, apply the idea of grouping in binary search algorithm to frame-slot ALOHA anti-collision algorithm, and on this basis, we propose an improved anti-collision algorithm to identify the collided tags in time slots quickly and correctly. The simulation results show that, the improved algorithm does improve the anti-collision performance, reduce the throughput of data, and improve the tag identification efficiency in RFID system.
