According to the characteristics of the collision, the algorithm searches forward and backward in a jumping manner to identify N tags, which requires a total of 2N-1 queries. The proof was given by mathematical induction. In addition, when the reader queries, the transmitted EPC parameters are dynamically transmitted in an indefinite length manner, and the information throughput can be further improved. The algorithm simulation results show that the improvement is 34.92%.
