Rapid coordinate system creation and mapping using Crickets

In this thesis, I describe a system that lays the foundation for context-aware applications. This system allows a user to set up a reference coordinate system in a room, using three Cricket listeners attached to a wooden frame. The system then assigns coordinates to Cricket beacons, which are placed on the ceiling. Finally, by using the frame in conjunction with a laser range finder, the user can generate a map of the room in the reference coordinate system, complete with features including doors, walls, and windows. This thesis also describes necessary changes we implemented that made the Cricket positioning system much more accurate.
