Bi-slotted Fast Query Tree-based Anti-Collision Algorithm for Large Scale of RFID Systems

Abstract

Radio Frequency Identification (RFID) technology uses anti-collision algorithms to avoid collision event and to achieve identified many of the tag in shared channel communication. Increasing the number of tags, make the collision problem is getting worse. In this article, we propose a new anti-collision algorithm which increases the system efficiency in large scale RFID systems. The simulation results show that the proposed algorithm, consider the tag identification process with improved efficiency compared with existing anti-collision algorithms.
