A SOA-Based Platform-Specific Framework for Context-Aware Mobile Applications

Context-aware mobile applications are intelligent applications that can monitor the user's context and, in case of changes in this context, consequently adapt their behaviour in order to satisfy the user's current needs or anticipate the user's intentions. The design of such applications relies on dynamic middleware platforms that consist of a variety of components. These components are distributed in the environment and interoperate by making use of each other's services. In the A-MUSE project, we defined a design methodology based on MDA principles that relies on a SOA reference architecture for context-aware mobile applications. This paper shows how abstract concepts in the design of such applications can be applied to realize concrete components that guarantee architectural interoperability. We also present a platform-specific framework that uses BPEL, UDDI registry and web services as target technologies to implement our reference architecture.
