<p>Smart sensors are small, low-cost, wireless computing devices that sense information such as light and humidity at extremely high resolutions. Smart-sensor technology has enabled a broad range of ubiquitous computing applications, such as agricultural, industrial, and environmental monitoring. Because sensors collect and transmit information while managing limited power and radio bandwidth, traditional approaches for deploying these applications requires months of design and engineering time. A smart sensor query-processing architecture using database technology can, however, facilitate deployment of sensor networks greatly reducing programming effort and time-to-deployment for many such applications. The authors describe the design and implementation of an architecture to support the building of data-collection applications using sensors. Users specify the data of interest through simple, declarative queries, just as in a database system, and the infrastructure efficiently collects and processes the data within the sensor network.</p>
