    Abstract: PURPOSE: A collision preventing system considering a channel state and an RFID(Radio Frequency ID) tag having mobility and a method thereof are provided to improve the recognition speed and reliability of an RFID system by improving the recognition rate when the RFID tag is moved. CONSTITUTION: An RN16 received from mobile RFID tags(10) coincides with an RN16 including an ACK, a first step processing module(22a) determines a collision and determines a transmission sequence by priority of RFID tags not having collisions. A second step processing module(22b) transmits information using the transmission sequence. The first step processing module transmits a first step start command including a frame size to enable the RFID tag receiving the start command to randomly select a slot to be transmitted in a frame size range.

    Abstract: PURPOSE: A network broadcast method using an MAC(Medium Access Control) unicast and a relay node is provided to minimize the loss of a data packet by preventing collision between an MPR(MultiPoint Relay) node and a source node. CONSTITUTION: A source node transmits a data packet to one or more first MPR nodes using an MAC unicast method. One or more first MPR nodes transmit the data packet to a second MPR node using the MAC unicast method. When one or more second MPR nodes are not existed within a first hop, one or more first MPR nodes transmit the data packet to a normal node using the MAC unicast method.

    Abstract: PURPOSE: A collision preventing system considering the mobility of an RFID tag and a method thereof are provided to improve a recognition rate by recognizing the RFID tag with an FSA(Framed Slotted ALOHA) method and recognizing RFID tags retrying more than reference times with an extra recognition method. CONSTITUTION: An RF transceiving unit(21) performs the wireless transceiving of an RF method with RFID tags(10). A recognition module(22a) transmits a recognition start command for recognizing an RFID tag in a recognition area of the RFID tags. The recognition module compares the number of collision times of the RFID tag receiving the command with a collision threshold in order to preferentially recognize an RFID tag higher than or the same as the collision threshold in a binary tree section. The recognition module recognizes an RFID tag lower than the collision threshold in an FSA section after the binary tree section.
