An anti-collision algorithm for RFID system

MA Zu-ju

Open publisher page 0 citations

Abstract

Radio frequency identification (RFID), with the advantage of identifying mobile and multi objects without touch and interference, has provided an excellent solution for achieving the transparency of supply chain information. However, tag collision is a key problem in the RFID system. In this paper, an improved anti-collision algorithm base on binary-tree searching of regressive Index is proposed. And the performance of the algorithm is illustrated by an example and simulation.
