摘要： 在时间敏感的大规模射频识别技术(RFID)应用中,为快速地检测出集合中丢失的标签,提出一种基于迭代识别的RFID丢失标签检测方法。通过对多轮检测过程中的历史检测信息进行迭代识别,挖掘帧时隙ALOHA中空时隙、单响应时隙和碰撞时隙中的信息,使得每一轮检测出存
在或者丢失的标签数量明显增加,从而提高整体的检测效率。实验结果证明,相比IIPS-CM协议,在不同的丢失率和丢失数量下,该方法都能降低丢失RFID标签的平均检测时间,其检测效率也具有较好的稳定性,不随丢失标签数量变化而变化。

Abstract: Due to its low cost and convenience,Radio Frequency Identification(RFID) technology is widely deployed in social life.In time-sensitive large-scale RFID applications,efficient RFID missing tag detection is a key problem.Based on analysis on recent research,a detection method based on iterative update is proposed.The method makes use of history information in each round,and acquires more information in empty slot,singleton slot and collision slot to identify more existing or missing tags,which improves the efficiency of detection.Compared with IIPS-CM protocol,it achieves higher performance as well as good stability under various rates,and does not change the number of missing tags.
