A Critical Survey and Analysis of RFID Anti-Collision Mechanisms

Free registration required

Executive Summary

The anti-collision mechanism is an important part of RFID systems. Many algorithms were proposed in the literature, but most of them were designed based on the theory of Random Access (RA) systems. In this paper, the authros review the various types of anti-collision systems and their corresponding algorithms. Different reading strategies are critically analyzed and compared by computer simulation. By comparing the different working mechanisms of RA and RFID systems, they show that a new theory is needed for the design and analysis of RFID anti-collision algorithm.
