超宽带射频识别(UWB-RFID)是一种将超宽带应用在射频识别中的短距离通信技术,基于UWB-RFID系统提出了一种新的反碰撞算法AURAC(Adaptive Ultra-Radio Anti-Collision Algorithm),算法包括预约机制和自适应M-FSA算法两个内容,其核心思想是利用UWB特性解决大量标签识别问题。实验结果证明AURAC算法与现有的算法相比,优化了系统的识别效率,且该算法的帧长开销和实现复杂度相对较小。
Ultra-wideband radio frequency identification(UWB-RFID)technology is a short-range munication technology that applies the advantage of UWB to RFID.Based on UWB-RFID system,this paper proposes an ultra-wideband adaptive anti-collision algorithm AURAC,which focuses on the issue of resolving a great deal of identification of labels with UWB multi-channel feature.It comprises two elements:reservation mechanism and adaptive M-FSA.Experiment results show that it has optimised the efficiency of the system identification compared with existing algorithms and has distinct advantage in frame overhead and implementation complexity.
