Method of finding metadata server

The present invention relates to a metadata search server, how to retrieve the metadata server USN (Ubiquitous Sensor Network) in a distributed environment (Distributed Environment). The invention is characterized by storing the location information of the metadata server using the location server cluster, and at the time of the client metadata search request, the search for the location of the metadata server, the metadata of a particular resource are stored in a distributed environment, . Accordingly, the present invention can be can provide to clients that use the metadata server metadata server side, simple and consistent interface in further reducing the overall cost and maintenance cost of the development to improve the transparency of service development . USN, the sensor, the sensor network, metadata, directory, a location server, point-to-point structure, the hierarchy
