Query Processing in Sensor Networks

sensors are small wireless computing devices that sense information such as light and humidity at extremely high resolutions. A smart sensor query-processing architecture using database technology can facilitate deployment of sensor networks. Recent advances in computing technology have led to the production of a new class of computing devices: the wireless, battery-powered, smart sensor. Traditional sensors deployed throughout buildings, labs, and equipment are passive devices that simply modulate a voltage on the basis of some environmental parameter. These new sensors are active, full-fledged computers, capable of not only sampling real-world phenomena but also filtering, sharing, and combinin
