System and method for supporting logical sensor networks

PURPOSE: A system and method for supporting logical sensor networks are provided to obtain necessary sensing data through a logical sensor network and a physical sensor network. CONSTITUTION: An LSN(Logical Sensor Network) generation module(111) generates logical sensor networks(120a-120c). If the state of a PSN(Physical Sensor Network) or the state of the sensor node within the PSN is changed, an LSN update module(113) updates meta data(112) of an LSN. If the query for the LSN is received from application programs(130a-130c), a query processing module(114) collects the sensing data from the PSN or the sensor node within the LSN. Through the use of the collected data, the query processing module provides the query result data for the corresponding LSN to the application program.
