A Simple and Efficient Anti-collision Algorithm for RFID System

Abstract

Radio Frequency Identification (RFID) has recently played an important role in wireless sensing network. However, if multiple passive tags are simultaneously transmitted to the reader, the reader is unable to identify the tags. This will reduce the efficiency of a RFID system. To solve this problem, we propose a modified anti-collision algorithm based on ALOHA protocol to improve the performance in a RFID system. Simulation results show that the proposed algorithm is better than that of traditional method.
