Improved Tag Identification Method for reducing the Process Time of Tag Recognition

In recent years, radio frequency identification(RFID) technology has moved from obscurity into mainstream applications that speed up in identifying objects(e.g. manufactured goods, healthcare services, etc.) which affect our daily lives. However, there are several issues arises such as RFID tag collision problem which occurs due to the usage characteristics of radio frequency communication. Therefore, to answer these issues, we proposed the tag identification method which uses a multi-reader to minimize tag collision and to reduce the tag recognition time. The proposed method analyze the tag recognition time by applying the adaptive group separation(AGS) algorithm. Based on our experimental results, the proposed method shows the improvement rate of over 40% increased on processing time.
