分组部分时隙帧预测的RFID防碰撞算法
RFID Anti-collision Algorithm of Grouping Part Time Slot Frame Prediction
摘要
Abstract
To solve the tags collision problem in Radio Frequency Identification( RFID) system where the maximum size of frame is limited, this paper proposes a new Grouping Part time Slot frame Prediction ALOHA ( GPSPA ) algorithm. Tags are divided into smaller groups considering the limited frame size ’ s capability. Part slots prediction scheme is used in identification to decide whether to change the frame size immediately. If the empty or collision slots percentage exceeds the threshold value, the frame size is changed promptly. Simulation results show that the proposed algorithm can increase the system efficiency and consume fewer slots than previous work. Besides,the influence of the parameters of the algorithm is discussed by simulation tests. The system identification efficiency can maintain 35. 58% , approximating to the limit value, where dynamic tags are changing greatly. The proposed algorithm provides a good solution for RFID systems where the tags are changing within a wide range and the frame size is limited.关键词
