Abstract: RFID technology is an important technology of the Internet of Things. The key to realizing large-scale applications is to improve the efficiency of the system. For this reason, a novel RFID anti-collision Q-value algorithm is proposed, which changes the Q-rounding of the original Q-value algorithm to 2Q rounding, so that the adjusted frame length is closer to the theoretical optimal value, thereby the convergence is effectively reduced. Slot utilization of time is improved. By comparison, the actual throughput of the improved algorithm remains at a high level (average is 0.311 3), the total number of time slots is reduced by 26.7% when it is compared with the original Q-value algorithm.
