Abstract

Tag identification is the most fundamental problem in Radio Frequency Identification (RFID) systems. Time efficiency is the top quality of service (QoS) metric in RFID tag identification. Traditional tag scanning approaches suffer from low time efficiency because they need to transmit tag IDs that are usually very long (e.g., 96 bits). In this paper, we investigate how to employ handheld readers to improve the time efficiency of tag identification and provide flexibility to scan tags on different purposes. A fast and flexible tag scanning mechanism called LOCK is proposed, which combines both the information and the replying slot index of a tag's response. In LOCK, tags transmit only short responses instead of tag IDs. Based on LOCK, we propose two novel tag scanning protocols that progressively add new techniques on top of one another to improve the time efficiency. Compared to the state-of-the-art solution in literature, our best protocol reduces scanning time by up to 53 percent.
