Abstract: RFID technology is a key technology of the Internet of things.In order to solve the problem of anti-collisionin RFID technology with a large number of tag data,a new Q value algorithm based on EPC-C1G2 was proposed in this paper.In this algorithm,the method of Q is improved effectively.Otherwise,combined with the label grouping algorithm,the proposed method achieves higher system efficiency in a large number of tag data.The simulation results show that the proposed algorithm can not only reduce the slot number,improve the time slot utilization,but also maintain a good system throughput rate.
