Application of Improved Anti-collision Algorithm of RFID in Warehouse Management System

RFID tag anti-collision is one of the key problems of radio frequency identification technology. Although the correct rate of binary anti-collision algorithm that is most used now is higher, the repeat search process affects the recognition speed. To improve the efficiency of the RFID tag identification system, the article improved the binary anti-collision algorithm. Then the article analyzed the performance of the improved algorithm. Reached a conclusion that compared with the binary algorithm, the improved algorithm could improve the efficiency of identification. Especially when the number of tags to be identified was large, the improved algorithm could save the time spent in identifying the labels significantly. Then the efficiency of warehouse operations was improved.
