Research on the anti-collision algorithm in radio frequency identification system

Tag anti-collision is one of the key problems of RFID system.In RFID system,when data transaction between more tags and one reader at the same time, the data collision will be caused, so a anti-collision algorithm must be adopt to solve the conflict.In this paper,the binary search algorithm and dynamic binary search algorithm are analyzed in detail, and a new anti-collision algorithm is put forward.The experiment proves that this algorithm is more effective to solve the problem of anti-collision for multi-target recognition in RFID system.
