Matching grouping dynamic frame slotted ALOHA for anti-collision in RFID systems
Juyi Qiao, Weidong Wang, Yinghai Zhang · 2011
In RFID system, one of key problems is collision between tags, and many methods have been proposed to solve problem. Framed Slotted ALOHA is a widely used algorithm in anti-collision field of RFID system. In this paper, Matching grouping Framed Slotted ALOHA Algorithm is proposed. Compared to conventional algorithms, this algorithm groups tags to match length of frame, and would resolve the Stray problem of tags at same time. The simulation results show that algorithm can improve average throughput of RFID system.
