Abstract
This paper introduces the radio frequency identification (RFID) technology and the RFID anti-collision algorithms. The application mode of the RFID dynamic grouping anti-collision algorithm based on fuzzy c-means (FCM) clustering theory is stated. The selection of RFID tag grouping indexes is presented. The steps of the proposed anti-collision algorithm are developed. The simulation results show the algorithm can improve the stability and the reading accuracy of the RFID system.
