Enhanced ALOHA-Based Anti-Collision Algorithm for Efficien RFID Tags Identification

Abstract

the main contribution in this paper is to propose an efficient anti-collision algorithm to enhance the efficiency of the RFID systems. The proposed algorithm resolves the collision problem by querying the collided slots only while excluding the idle slots from subsequent processing, and using different methods for estimating the backlog number as means for adjusting the frame length. A simulator is designed for analyzing the performance of the proposed and several recent algorithms. Simulation results conclude that the proposed algorithm achieves higher performance than other compared algorithms and verifies its superiority for implementing RFID systems, specifically at large scale applications.
