Improved CT Algorithm Based on Bit Transform

Abstract

The RFID system is the core technology of the future Internet of Things system and Industry 4.0, and the RFID anti-collision algorithm is the basis for realizing the communication between the tag and the reader. Aiming at the problems of high computational complexity, low recognition efficiency and complex recognition process in existing RFID anti-collision algorithms in existing international standards, based on the query tree algorithm, combined with the extended bit transformation method, a relatively simple method is proposed. We propose a relatively simple anti-collision algorithm for RFID: Improved Collision Tree based on Bit Transformation Algorithm (ICTBTA). The simulation results show that the system efficiency of the tree algorithm proposed in this paper can be stabilized at more than 80%, and the efficiency of the currently used CT algorithm can be improved by more than 50%. Therefore, ICTBTA can be applied to common RFID passive tag identification systems.
