A Novel Fast Anti-Collision Algorithm for RFID Systems

Tag anti-collision algorithm for RFID system is a significant issue for fast tag identification. This paper presents a novel fast tag anti-collision algorithm called DJ (Detection and Jump) algorithm which splits the tag reading procedure into two steps including Collision Detection and Jump Reading. The proposed new algorithm highly improves the tag reading efficiency comparing to the popular Q-algorithm in EPC (Electronic Product Code) international standard. Our simulation evaluations show that the proposed DJ algorithm outperforms Q-algorithm in both identification delay and power consumption.
