Abstract
An apparatus for providing sensor network information receives sensing information containing sensing values obtained by sensor resources from sensor network middleware, converts the sensing information into an RDF (resource description framework) form, and stores and manages it in an RDF storage. The apparatus searches for information corresponding to a query from an application service, from among the information stored in the RDF storage, and provides it to the application service.
Claims17
A method for providing sensor network information in an apparatus connected to sensor network middleware, the method comprising:
- receiving sensing information containing sensing values obtained by sensor resources from the sensor network middleware;
- converting the sensing information into an RDF (resource description framework) format and storing the same in an RDF storage;
- analyzing a query provided from an application service;
- and
- searching for information corresponding to the query, among the information stored in the RDF storage, based on the analysis result, and providing the same to the application service.
An apparatus which is connected to sensor network middleware and providing sensor network information, the apparatus comprising:
- a middleware interface processor that interfaces with the sensor network middleware;
- a middleware query processor that receives sensing information containing sensing values obtained by sensor resources from the sensor network middleware;
- an RDF converter that converts the sensing information into an RDF (resource description framework) form;
- a storage that stores the sensing information in the RDF format;
- a query analyzer that analyzes a query provided from an application service;
- and
- a query processor that searches for information corresponding to the query, among the information stored in the RDF storage, based on the analysis result, and provides the same to the application service.
