Sensor-gateway apparatus based ubiquitous sensor network, system for providing application service using the same and method for providing user context date based ubiquitous sensor network
A sensor gateway apparatus based on a ubiquitous sensor network, a system for providing an application service by using the same and a method for providing user circumstance information based on the ubiquitous sensor network are provided to prevent information loss due to unexpected communication disablement and reduce development costs. A sensor data collecting unit(24) collects sensor data about circumstance information of a user measured with at least one sensor adhered to the user or a thing. Sensor data are transmitted to a data management unit(21) from the sensor data collecting unit. The data management unit extracts sensor data corresponding to a predefined data format, a user profile and requirements according to a query of an application service system. A transceiver(27) receives the query of the application service system. The transceiver transmits the sensor data in the application service system.
