Modeling the Anti-Collision Process of RFID System by Markov Chain

In recent years RFID technology has become very popular in many service industries, purchasing and distribution logistics, industry, manufacturing companies and material flow systems. In RFID system, one of the problems that we must solve is the collision between tags which lowers the efficiency of the RFID system. Framed Slotted ALOHA is a common used algorithm in anti-collision field. In this paper, we use Markov Chain to model the identification process of FSA algorithm. Then method to improve the system efficiency is proposed. According to analysis, the method shows better performance than conventional algorithm.
