一种时间高效的易于实现的多标签射频识别技术
A Time-Efficient and Easy-to-Implement RFID Technology for Multiple Tags
摘要
Abstract
Multiple tags collision problem severely degrade the identification efficiency of an RFID system.Based on the research of sub-frame observation mechanism,a sub-frame based dynamic framed slotted Aloha (SUBF-DFSA) algorithm is presented to tackle the high computation complexity and low time efficiency existing in the conventional DFSA algorithm.The SUBF-DFSA algorithm makes effective use of the idle and collision statistics during a sub-frame to estimate the tag backlog,determine the optimal frame size for the next identification round,so that it can dramatically improve the identification efficiency of an RFID system with large volume of tags.It is easier to implement into the conventional RFID reader because of the low computation overhead.Simulation results are supplemented to demonstrate the advantages of the proposed algorithm in achieving low computation complexity,good stability,and high identification efficiency compared to the traditional Aloha-based algorithms.关键词
