Internet of Things (IoT) has attracted much attention today. As the key component of IoT, the Radio Frequency IDentification (RFID) network has been growing in usage. An RFID network is composed of a backend system (including the database), one or more readers, and several RFID tags. Most of the RFIT tags cannot transmit signals actively, except the active RFID tags. The active RFID tags may gather information from sensors and store the information for later delivery to the reader. To extend the coverage of the RFID network, some RFID multi-hop relay systems (using active RFID tag as relay tags) have been proposed.
