Radio Frequency Identification (RFID) is a technology that uses radio frequency signals to identify objects. RFID is one of the key technologies used by the Internet of Things (IoT). This technology enables communication between the main devices used in RFID, the reader and the tags. The tags share a communication channel. Therefore, if several tags attempt to send information at the same time, the reader will be unable to distinguish these signals. This is called the tag collision problem. This results in an increased time necessary for system identification and energy consumption. To minimize tag collisions, RFID readers must use an anti-collision protocol. Different types of anti-collision protocols have been proposed in the literature in order to solve this problem. This paper provides an update including some of the most relevant anti-collision protocols.

“…[6]With RFID technology, Wal-Mart can detect the product information in real time, which greatly enhanced the supply chain efficiency of Wal-Mart, However, because RFID technology standards were still not perfect at that time, the production cost of RFID tags was high, and the high RFID label leakage rate led to the full development of RFID in Wal-Mart's supply chain. Today, the price of RFID tags has dropped to a few cents from the first generation of $ 1.25 in 2003, [7]and the high cost of labeling is no longer a problem, and with the continuous improvement of RFID protocols in recent years, RFID technology has made rapid progress Development, this project through in-depth study of the effective distance of medium-power card reader produced by Guangzhou East Core Technology Co., Ltd. under ISO5693 agreement, found and mastered the valid card reading range and card reader blind zone of the card reader under the ISO15693 protocol.…”

Abstract. The valid distance range of the reader of 13.56MRFID card reader is obtained through the theoretical inference and actual measurement of the reading distance of the RF card reader according to ISO14443A and ISO15693 protocols, and the mathematical modeling is made to obtain a more accurate effective distance The model can provide a reliable theoretical support for the layout and leakage rate of RFID card readers.

“…Generally, the existing RFID tag identification protocols can be classified into two categories [10,11]: ALOHA-based protocols [27][28][29][30] and tree-based protocols [19,31]. In ALOHA-based protocols, on average a tag needs to transmit its ID e times to the reader before being successfully identified [10,27], where e is the base of natural logarithm whose value is approximately equal to 2.72.…”

Radio Frequency Identification (RFID) is a key enabling technology of Internet of Things (IoTs) and has attracted much research attention in recent years. RFID can support automatic information tracing and management during the management process in many fields. A typical application of RFID is modern warehouse management, where products are attached with RFID tags and the inventory is managed by retrieving tag IDs. Many practical applications require searching a group of tags to determine whether they are in the system or not. The existing studies on tag searching have mainly focused on improving time efficiency and paid little attention to energy efficiency that is extremely important for active tags powered by built-in batteries. To fill in this gap, this paper investigates the tag searching problem from the angle of energy efficiency. We first propose an Energy-efficient tag Searching protocol in Multiple reader RFID systems, namely ESiM, which pushes per tag energy consumption to the limit as each tag needs to exchange only one bit
