Event-based Communication for Location-based Service Collaboration

Location-based context-aware services for mobile users need to collaborate in disparate networks. Services come and go as the user moves and no central repository is available. The user’s personal information and service usage statistics need to be protected. To support service collaboration we propose a service infrastructure that relies on an event-based serviceoriented architecture. We implemented a basic version of the architecture and used it for a tourism information system. An advanced version has been modelled using formal methods to evaluate privacy aspects. This paper reports about both architectures and our experiences of their application to tourismrelated services.
