New data sources and sensors bring new possibilities for terrain representations, and new types of characteristic errors. We develop a system to visualize and compare terrain repr...
We describe an experimental public resource monitoring system that combines sensor data and human input to create a new descriptor of ambient water conditions. We call this new me...
—Recently, wireless sensor networks have been proposed for assisted living and residential monitoring. In such networks, physiological sensors are used to monitor vital signs e.g...
—The overlay-based network architecture has been recognized as an effective way to deal with the funneling effect in sensor networks, where sensors closer to the sink are usually...
In-network sensor query processing systems (ISQPs), or sensor databases, have been developed to acquire, process and aggregate data from wireless sensor networks (WSNs). Because W...
