摘要: The present invention relates to a method of searching a metadata server that searches ubiquitous sensor network (USN) metadata servers in a distributed environment. The present invention stores location information on the metadata servers by using a location-server cluster and searches a location of a metadata server in which a specified resource metadata is stored, during a metadata searching request by a client. Accordingly, the present invention can provide a simple and consistent interface to the client using the metadata management servers in terms of the metadata servers and can improve the clarity of service development and can reduce the entire development costs and the maintenance and repair costs.
