Demo: A Generic Platform for Sensor Network Applications

Writing applications for sensor networks often involves low-level programming. In this demo we show a generic sensor network platform (SwissQM/SwissGate) that provides a high level interface for programming sensor networks and also provides a multi-tier architecture for efficiently handling and optimising the operation of the network. The demo is based on a small scale (deployment in a building) where the network is used concurrently by several applications to measure heating, ventilation, and air conditioning control (HVAC) parameters. The network also implements several event detection functions for fire, burglar, and user triggered alarms. In the demo we show how the sensor network can be programmed using queries in several languages (SQL, Java, XQuery), including user-defined functions (in a C-like language) and the results obtained as a stream of data tuples. We also show the ability to efficiently use the network concurrently.
