Abstract: The identification of RFID tags in small-medium regions usually adopts the reader network to realize, which is because multiple readers can statically implement the reader’s full coverage of the unrecognized tags. However, it is faced with high cost of readers, collision between readers and low tag identification ratio. In order to improve these problems, a performance evaluation method of single reader movement RFID system is proposed for small?medium regions, which takes the tag loss ratio and the total identification lap number as indicators, and the performance of the existing anti-collision algorithms is evaluated in the single reader movement RFID system. The experiment determines whether the reader can recognize the tag successfully by judging the current slot type, and the position of the reader is adjusted once for every 1 slot consumed, so that the signal area and the area tags are re-determined, until the end of the reader tag recognition task. So the simulation results show that this method can effectively evaluate the performance of various existing tag protocols in the small-medium RFID tag recognition environment, and improve the efficiency of RFID system.
