基于空闲时隙消除的超高频RFID防碰撞算法
Idle Slots Elimination Based Anti-collision Algorithm for UHF RFID
摘要
Abstract
Tag collision avoidance is a critical issue in RFID system.In order to further improve the performance of RFID system and reduce the computation complexity,an efficient idle slots elimination anti-collision algorithm based on binary splitting (ISE-BS) is proposed.In ISE-BS,one bit control flag signal is introduced to transmit before data exchange,where tag collision can be informed by control signal and the unnecessary data exchange between a reader and tags can be further avoided.Since the idle slots during BS algorithm are eliminated by ISE-BS,coordination transmission time of identification process is saved.Simulation results show that the proposed ISE-BS algorithm achieves throughput of 0.4065 and time efficiency of 0.3247,outperforms the existing anti-collision algorithms.To the view of implement,we compare the floating point operations(FLOP) cost of various algorithms.The results show that the proposed algorithm significantly reduces the system’s complexity.关键词
