SYSTEM AND METHOD FOR SUPPORTING LOGICAL SENSOR NETWORK
First Claim
1. A system for supporting a logical sensor network (LSN), comprising:
- a metadata database (DB) for storing metadata of a plurality of available physical sensor networks (PSNs) each having a plurality of sensor nodes;
a LSN generation module for generating a LSN including one or more PSNs among the PSNs stored in the metadata DB or one or more sensor nodes in the PSNs, and storing metadata of the generated LSN in the metadata DB;
a LSN update module for updating the metadata of the LSN including the PSNs or the sensor nodes in the PSNs when a state of the PSNs or the sensor nodes is changed; and
a query processing module for, when a query about the LSN is received from an application program, collecting sensing data from the PSNs or the sensor nodes included in the LSN, generating query result data for the LSN using the collected data, and providing the query result data to the application program.

Abstract
Provided are a system and method for supporting a logical sensor network (LSN) separate from an actual physical sensor network (PSN) to readily obtain sensing data required by a user or application program in an environment consisting of various types of PSNs. The system includes a metadata database (DB) for storing metadata of a plurality of available PSNs each having a plurality of sensor nodes, a LSN generation module for generating a LSN including one or more PSNs among the PSNs registered in the metadata DB or one or more sensor nodes in the PSNs, and storing metadata of the generated LSN in the metadata DB, a LSN update module for updating the metadata of the LSN including the PSNs or the sensor nodes in the PSNs when a state of the PSNs or the sensor nodes is changed, and a query processing module for, when a query about the LSN is received from an application program, collecting sensing data from the PSNs or the sensor nodes included in the LSN, generating query result data for the LSN using the collected data, and providing the query result data to the application program.

12. A method of supporting a logical sensor network (LSN), comprising:
-
generating a new LSN including one or more physical sensor networks (PSNs) or one or more sensor nodes in the PSN, and storing metadata of the generated LSN in a metadata database (DB); when a state of the PSNs or the sensor nodes in the PSNs is changed, retrieving the metadata of the LSN including the PSNs or the sensor nodes from the metadata DB, and updating the metadata; and when a query about the LSN is received from an application program, collecting sensing data from the PSNs or the sensor nodes included in the LSN, generating query result data for the LSN using the collected data, and providing the query result data to the application program. - View Dependent Claims (13, 14, 15, 16, 17, 18)
