Middleware Solutions for Effective Cloud-CPS Integration in Pervasive Environment

The proliferation of a wide range of highly different mobile devices, from tiny sensors to powerful smartphone, with increasing connection abilities, has led to the modification of the way we interact with the surrounded environment. It is growing the manifest need of intermediate middleware solutions that can effectively integrate device localities with the global cloud resources, overcoming the issues related to their direct connection. In this thesis work, the primary objective is to present some promising and feasible real-world solutions, trying to face and cover many different challenges and open-points of the mobile devices applications. The solutions proposed are applied at different levels of the stack, thus dividing them in relation to their internal architectures, in order to underline the intrinsic characteristics associated with the architectural solution, the requirements mainly stressed, and highlighting the most suitable scenarios they can work with. This thesis work aims to push forward the research in the field, mainly based on theoretical architecture and methodological approaches so far, introducing some industrially-relevant implementations, grouped in relation to the specific applications to face, that specifically target the issues of practical feasibility, cost-effectiveness, and efficiency of middleware solutions over easily-deployable environments. The described solutions are specifically designed for the support of mobile services, also in hostile environments, with the main requirements to provide and greatly increase mobile devices requirements. The designs, implementations, and experimental works demonstrate the suitability of the proposed solutions to address several different open points and challenges of mobile devices applications in an efficient and effective way and, also, with applications in large-scale scenarios. Finally, as notable side effect of the present work, the present work present a complete overview of the very recent literature about the intermediate middleware that are emerging.
