Open publisher page 1 citations

Abstract

In RFID systems,one of the problems is the collision between tags,a major issue affecting system performance.This paper detailsthe analysis of several commonly used anti-collision algorithms,i.e.ALOHA algorithm,framed slotted ALOHA algorithm,and dynamic framed slotted ALOHA algorithm.Based on the analysis,the paper proposes a new ALOHA algorithm.The simulation and analysis have shown that with the proposed algorithm the maximum system throughput can reach up to 53% and the efficiency of RFID systems is improved.
