Mobile Cloud Application Models Facilitated by the CPA

This paper describes implementations of three mobile cloud applications, file synchronisation, intensive data processing, and group-based collaboration, using the Context Aware Mobile Cloud Services middleware, and the Cloud Personal Assistant. Both are part of the same mobile cloud project, actively developed and currently at the second version. We describe recent changes to the middleware, along with our experimental results of the three application models. We discuss challenges faced during the development of the middleware and their implications. The paper includes performance analysis of the CPA support for applications in respect to existing solutions where appropriate, and highlights the advantages of these applications with use-cases.
