METHOD AND SYSTEM FOR DATA AGGREGATION IN A SENSOR NETWORK

A sensor profile based data aggregation method for aggregating data in a sensor network, which includes a plurality of sensor nodes, is provided. This method includes steps of determining types of sensors included in the sensor nodes, and generating a sensor profile that includes information on each type of the sensors. The information includes a filtering criterion and aggregation operators defined for the each type of the sensors. Once the sensor profile is created, the profile is parsed into a header file, and the header file is compiled with other sub-modules to generate a sensor profile based aggregation module. The sensor profile based aggregation module is installed in each of the sensor nodes. Whenever, sensor data is received in the sensor node, the data is filtered according to the filtering criterion defined in the sensor profile, and data aggregation is simultaneously with given operators.
