Over the past decade when RFID (Radio Frequency Identification) technology is fully employed in areas, the redundant data processing in the actual system is one of the most important aspects, which furthermore affects the accuracy and the working performance of the system and leads to the waste of devices resource. Based on the previous algorithms like RRE and LEO, this paper works out an algorithm, TCBA (Three-step Count Based Algorithm), using the number of neighbor readers and the count of the tags which are covered by the neighbor readers as factors to remove the redundant readers. The simulation results show that our algorithm can substantially eliminate more redundant readers than RRE and LEO.
