1. Cougar (Sensoria Node) A platform for testing query processing techniques over ad-hoc sensor networks. Three-tier architecture : – The QueryProxy, a small database component that runs on sensor nodes to interpret and execute queries. – The Frontend component, which is a more powerful QueryProxy that permits connections to the world outside of the sensor network. – A graphical user interface through which users can pose ad- hoc and long-running queries on the sensor network.

2. Node Capabilities Processing – Aggregation of network data – In network processing of data Sensing – Accoustic – Seisimic – Passive IR

3. Online Demo Visit: http://cougar.cs.cornell.edu/public-demo.php http://cougar.cs.cornell.edu/public-demo.php – QueryProxy demo applet – SimTracker demo applet – Also available in java jar file format

4. Query Proxy and Sim Tracker Query Proxy – Interface to view results of many network queries – Networked: remote connection to query server available with multiple concurrent connections Sim Tracker – Simulates Activity sensed by sensor network – Simulates: Pedestrian, Bike, Car, Tank, etc.
