UBIQUITOUS SENSOR NETWORK SYSTEM AND OPERATION METHOD THEREOF

摘要

PURPOSE: A ubiquitous sensor network system and an operating method thereof are provided to wirelessly transceive a signal with a zigbee coordinator of a main USN(Ubiquitous Sensor Network) through a relay device. CONSTITUTION: A main USN(110) comprises a zigbee coordinator and a plurality of main sensor nodes. A local USN(120) comprises a plurality of local sensor nodes. A relay device(R) is installed between the zigbee coordinator and the local sensor node. The relay device transmits and receives a signal to and from a plurality of local sensor nodes of the local USN. The relay device transmits and receives a signal to and from the zigbee coordinator.
