SENSOR NETWORK SYSTEM USING HYBRID BRIDGE NODE SUPPORTING WIRED COMMUNICATION AND WIRELESS COMMUNICATION

摘要

PURPOSE: A sensor network system using a hybrid bridge node which supports wired/wireless communication is provided to operate two sensor networks as one sensor network by converting a first wireless sensing data packet into a first wired sensing data packet. CONSTITUTION: Sub sensor networks(102,103) are installed in a first area. Each sub sensor network includes a first sensor node and a first hybrid bridge node. A main sensor network(101) is installed in a second part. The main sensor network includes one or more second sensor nodes and one or more second hybrid bridge nodes.
