Recent advances in hardware and wireless technologies have led to the developments of small, wireless, battery-powered sensors with limited processing power. Sensor networks consisting of hundreds or even thousands of such sensors can be deployed to monitor physical environments with little human intervention. Various constraints of sensor network, such as unreliable wireless connections, limited bandwidth and finite energy, have posed the needs for flexible, reliable, and cost-effective techniques for processing data collected by the sensors. A sensor network can be treated as a database. Collecting and processing the data collected and stored in the sensor network can be achieved using queries. In this thesis, we focus on join queries in sensor networks, which are used to integrate data from the raw sensor readings.
