Abstract

In RFID field, it is easy to interfere between adjacent channels as the frequency band and channel bandwidth are narrow. Especially, in case of the dense reader mode where the number of readers is more than the number of channels, the readers easily collide with each other. In this paper, we propose an algorithm to avoid reader collision in dense reader environment. First, we introduce the operation of our algorithm. And next, we show the simulation results of the proposed algorithm. Simulation results show performance improvement of our algorithm compared to existing LBT algorithm.
