Support for Context-Aware Collaboration

This paper describes a middleware architecture with its location inference service (LIS), and an application for context-aware mobile collaboration which is based on this architecture. The architecture, named Mobile Collaboration Architecture - MoCA comprises client and server APIs, a set of core services for registering applications, monitoring and inferring the execution context of mobile devices, in particular their location. This architecture is suited for the development of new kinds of collaborative applications in which the context information (connectivity, location) plays a central role in defining both the group of collaborators, and the communication mode.
