Improvement on the Binary Anti-collision Algorithm Based on RFID

The research on anti-collision algorithm for the label of RFID was carried out in this paper.The theory of binary anti-collision algorithm and binary search algorithm in RFID system were introduced,based on which,the improvement of the algorithm was proposed.The encoder mode needed by the binary algorithm together with the basic principles of instruction and algorithm were all introduced,and the workflow of the algorithm was explained through example.From three aspects of the communication frequency,transmission delay and throughput of the reader,the improved binary algorithm was simulated and analyzed.The results show that the performance of the improved algorithm is higher than that of binary search algorithm.
