Abstract: Classic RFID tag anti-collision protocols mainly aim at the identification of tags in small area. That is, all unidentified tags are located in the reader's read-write region. When there is one or more tag outside the reader coverage area, multi-reader RFID system is an effective method of identifying all tags. However, the cost of multi-reader RFID system is much higher than that of a single reader system. There are many other tag identification scenes where tag distribution area is only slightly larger than a reader coverage area. For the scene, in the paper, we let the all tags, including outside the reader coverage area, have an opportunity to enter the reader coverage area by moving reader and be identified. The scene is called single mobile reader systems (SMRS) at the paper. However, SMRS cause the tag reappearance phenomenon (TRP), which leads to the multiple identification problem of tag (MIPT). TRP and MIPT make low the effective tag identification efficiency happen. In the paper, we propose an improved EPC C1G2 protocol, which can decrease MIPT effectively and increase tag identification efficiency.
