标签移动场景下的防碰撞算法研究

ag collision is one of the most common and difficult problems in RFID system. Solving the collision problem and reducing the tag recognition time are of great significance for the application of RFID. In order to solve the problem that some existing anti-collision algorithms were mostly applied in tag fixed scene but had poor performance in tag moving scene, this paper proposed an anti-collision algorithm in tag moving scene (TMS) . The algorithm first distinguished between the move-in tag and the resident tag, and then estimated the number of tags, finally used a hybrid recognition strategy to identify the tag based on estimated number of tags. The simulation results show that compared with other algorithms, TMS algorithm can effectively reduce the tag recognition time in tag moving scene, which has certain significance for the research of RFID tag anti-collision algorithm.
