Our research targets collaborative environments with focus on mobility and teams. Teams comprise a number of people working on multiple projects and activities simultaneously. As mobile and wireless technology advances people are no longer bound to their offices. Team members are able to collaborate while on the move. Sharing context information thus becomes a vital part of collaborative environments. However, challenges such as heterogeneous devices, connectivity, and bandwidth arise due to the dynamic nature of distributed, mobile teams. We present a methodology for context modeling and employ a framework that reduces costs such as computing information and usage of network resources by transferring context at relevant levels of detail. At the same time, robustness of the system is improved by dealing with uncertain context information. Our framework is implemented on an OSGi container platform using Web services for communication means.
