“…First, the maximum interrogating range of an RFID reader is limited to the distance where the passive tags' chips can receive enough power to turn on themselves (the range is usually less than 10 meters) [27], [50]. Second, most RFID systems are installed in supermarkets, warehouses or on the conveyor belts, where the communication condition of every tag within the reader's range are almost the same [2], [8], [9], [25], [27], [30], [31], [33]- [38], [51]. Note that, in typical RFID systems, tags communicate and power themselves using same RF waves radiated by the reader antenna [10], [52].…”

“…In other words, the reader sends its energy through the antenna as RF waves to tags in order for them to become energized and respond back to the reader. Third, this transmission setting assumption has been widely used to evaluate the performance of various promising tag management protocols in RFID systems [2], [9], [25], [30], [31], [33]- [36], [38], [51], [53].…”

Internet of Things (IoT) has gained great popularity in various fields including smart warehouse and intelligent manufacturing. As a building block of IoT network, the Radio Frequency IDentification (RFID) technology enables a large and ever-increasing number of physical objects to be monitored across the Internet via tag identification. Efficiently managing massive tags in RFID systems becomes an important research issue for IoT networks. This paper focuses on a fundamental management problem -tag-sorting, which is to (1) put a set S of identified tags into a certain order by informing each tag t ∈ S of a unique integer ∆(t) ∈ {1, 2, • • • , |S|}, and meanwhile (2) keep unidentified tags from receiving any of these integers. For RFID systems, it is critical to solve this problem as quickly as possible in the sense that, once sorted, every identified tag t ∈ S can be manipulated via t's log 2 (|S|)-bit integer significantly shorter than t's 96-bit long tag-ID (log 2 (|S|) 96), boosting efficiency substantially. The existing works of literature, however, fails to solve this problem rapidly, as they accomplish (1) and (2) separately by using aloha-like protocols and Bloom filters, which incur a long communication time far from the optimum. In this paper, we overcome this drawback by proposing a protocol P sort capable of solving the problem fastly. In particular, this protocol is built with a novel data structure and communication scheme to achieve (1) and (2) simultaneously by using a communication time proven to be much less than the stateof-the-art protocols. The simulation results demonstrate the competence of P sort in achieving about 1.4× speedup than the state-of-the-art solutions.INDEX TERMS IoT network, edge server, RFID systems, tag management, tag-sorting, unidentified tag, identified tag.
