Tag Anti-collision Algorithm for Grouped Frame Time Slots Based on Idle Time Slot Detection Mechanism
Multi tag collision is an unavoidable problem in radio frequency identification systems.A large number of tag collisions can increase the energy consumption and time cost of the system,seriously affecting the recognition efficiency of the system.To this end,a new tag anti-collision algorithm is proposed,which combines the advantages of traditional frame slot algorithms that are simple and easy to implement.At the same time,grouping and idle slot detection mechanisms are introduced to minimize detection slot overhead,eliminate idle slots in the recognition process,and reduce the probability of tag conflicts.The simulation results show that compared to the FuzzyQ algorithm and the frame slot ALOHA algorithm,the average throughput of this algorithm has been improved by 22.64%and 61.74%,and the system communication transmission has been saved by 16.73%and 30.41%on average.
