Abstract
The location of equipment, people, and other physical things is essential data to many emerging applications. Unfortunately, location data is often not easy to obtain. We have created SpotON to investigate ad-hoc location sensing, a flexible alternative to infrastructure-centric location systems. SpotON tags use received radio signal strength information as an inter-tag distance estimator. In this paper, we describe ad-hoc location sensing and the SpotON approach. We present specific results regarding calibration of the SpotON radios and suggest directions for further research.
