Research on RFID Label Identification Algorithm Based on Collision Bit Eigenvalue
Massive labels will be deployed in the system perceptive layer of"Artificial Intelligence&Internet of Things(AIoT)"network.To quickly obtain information about items with pasted labels,a label anti-collision algorithm based on eigenvalue strategy is designed.By combining the binary characteristics of electronic label ID identification codes and exclusive or operation,any two collision bits can be accurately inferred,thereby eliminating queries for invalid nodes and accelerating the query process.The simulation results show that the proposed algorithm reduces the idle time slot and the total number of queries effectively,and improves the system efficiency.When the number of labels is 20 000,the system efficiency of the proposed algorithm reaches 0.43,which is 24%higher than that of the classical query tree algorithm,and the total number of queries decreased by 10 905.
