摘要： For a sensor network having reference nodes and sensor nodes, A method and apparatus using a distance determining algorithm for a sensor network having reference nodes and sensor nodes. A distance determining algorithm is executed to determine an adequate distance between reference nodes within a preset error range, and a position location table is created. A sensor node sends a location information request to reference nodes, receives the position location table and location information from the reference nodes, and computes the coordinates of its position. Alternatively, without requesting transmission of the position location table, the sensor node may receive calculated coordinates of its position directly from a reference node.

摘要： Method for rapidly detecting identifier (ID) of tags, by radio frequency identification (RFID) reader in communication system that includes RFID reader and at least two tags communicating with RFID reader, is provided. RFID reader generates a prefix when IDs contained in at least two messages received collide with each other, prefix including a first colliding bit, which is set to ‘0’ or ‘1’, from high-order bits and non-colliding high-order bits. RFID reader sends a first message containing information that requests transmission of an assigned ID in a preset transmission period when the bits of the generated prefix match bits corresponding to the prefix, in the assigned ID. Tags receive a first message that contains a prefix including at least one bit, and sends a second message containing an assigned ID during a preset transmission period when the bits of the prefix match bits corresponding to the prefix, in assigned ID.
