Formal specification of an intelligent message notification service in an infostation-based mLearning system using CCA

The Calculus of Context-aware Ambients (CCA in short) has been proposed as a notation that is suitable to model mobile applications that are context-aware. This paper considers a real-world case study of an infostation-based mLearning system in which mobile devices such as hand-set phones, PDA's and laptops can access a number of services and communicate to each other within a university campus. Such a dynamic system must enforce complex policies to cope with mobility and context-awareness. We show how policies can be formalised using CCA, and validated using the execution environment of CCA. We illustrate how properties can be validated using our approach.
