WSNs are usually composed of small, low cost devices that communicate wirelessly and have the capabilities of processing, sensing and storing. A sensor network consists of an array of numerous sensor networks of diverse types interconnected by a wireless communication network. The system extracts relevant information from the available data. Sensor data is shared between these sensor nodes and used as input to a distributed estimation system. This data is then forwarded via internet or other gateways to the user where the next course of action will be decided.
