摘要
针对射频识别系统(RFID)标签碰撞问题,本文结合较常用的两种防碰撞算法的优点,提出了一种新型RFID联合防碰撞算法,从而有效地提高了系统吞吐率,缩短了标签读取时间。仿真结果表明此种新型联合防碰撞算法的吞吐率比改进的动态帧-时隙(IDFSA)算法提高了57.30%。
Focusing on the tags collision problem of Radio Frequency Identification （RFID） system,this paper proposes a new com-bined anti-collision algorithm in RFID by combining the merits of the two usual algorithms. This new algorithm effectively improvesthe throughput and shortens the reading time. The simulation indicates that the throughput of this new algorithm is higher than thatof Improved Dynamic Framed—Slotted ALOHA （IDFSA）algorithm by 57.30%.
