To further enhance the performance of the Internet of things tag identification anti-collision

by researching and analyzing the binary tree anti-collision algorithm and its improved algorithms

an improved bitlocked tag anti-collision algorithm is proposed.Before processing of bit-lock anti-collision

the algorithm divides all the identification tags into two groups according to the parity of the bit sum of each tag

to reduce the occurrence of tag collisions and improve the ability to identify two tags one time.Simulation results show that the tag identification performance of the improved algorithm is better than the original algorithm

this advantage is more obvious when the tag is more focused.
