Abstract

With the recent developments in RFID systems, many readers are needed to apply to the same work place, which easily leads to the reader collision. When the communication with tags of a reader is disturbed by the operation of other readers, a reader collision will occur, which is achieved less attention than the tag collision in previous studies. To solve several types of reader collisions, we propose an efficient multi-channel reader collision avoidance (EMRCA) protocol, which is suitable for the multiple readers RFID system. After analyzing the relationship between the distance of two readers and the types of reader collisions, we give the solutions of reader collisions, and present the principle of choosing data channels. Using several data channels, the new processing procedure of communication with tags is designed, in which the neighbor readers and the relevant readers have the different communication principles. The simulation results show that the proposed protocol has many better performances than the previous protocols in terms of the number of failed interrogations, the process time of interrogation, and the network overhead.
