Executive Summary

As computing devices and their users become increasingly mobile, the demand for information about the environment, or context, becomes of significant importance. Applications must be able to adapt themselves to the changing environment to satisfy users' demands and to ensure that the application's resource usage matches the environment's capabilities. However, using traditional means, acquiring this context information can be very expensive because collecting it usually requires communication among mobile devices. In this paper, the authors explore the possibility of collecting reasonably accurate context information passively.
