Conclusions & Future Work
Requirements Analysis for Mobile Community Cloud Platform: existing
commercial CC solutions not ready for mobile requirements
Conceptual design of Mobile Community Cloud Platform (MCCP)
All single components available (also for mobile)
Main Challenges:
– Integration of components
– Distributed evaluation
Research questions:
– Where is the connection between Cloud computing and mobile communities?
– What are the prominent use cases?
– How do we evaluate them?
– How to successfully support mobile communities applying Cloud computing idea?
