Research on anti-collision algorithm in Radio Frequency Identification system

In the RFID system,the anti-collision algorithm is used to avoid the data collision resulted from the data transaction between more tags and the reader at the same time.Anti-collision technique is a key technique in the RFID system.In this paper,the binary search algorithm and dynamic binary search algorithm is analyzed in detail,and a new anti-collision algorithm is put forward.According to the characteristics of the tags collision,the algorithm applies the obtained collision information and the method of the dormancy count,which improves identification efficiency and reduces the search range.Moreover,the performance analysis shows that the algorithm has more obvious advantages than the binary search algorithm and the dynamic binary search algorithm.
