INFORMATION SERVICE SYSTEM USING USN NODES AND NETWORK, AND SERVICE SERVER CONNECTABLE TO USN NODES THROUGH NETWORK

摘要

An information service system using USN nodes, a network and a service server connectable to ubiquitous sensor network (USN) nodes through the network are disclosed. The information sensed by the USN nodes is transmitted to the service server connected to an external network, so that an administrator can check the context of surrounding environment where the USN nodes are installed, through the service server. The operation command for a specific object associated with a specific USN node, input by an administrator accessed the service server, is transmitted to the USN node via the network, so that the USN node can operate the specific object. The USN can be established at relatively small size, reducing installation costs, maintenance fees, and resource waste. Thus, the USN can be widely used in the applications.
