Mobile Device Computation Offloading over SocialVPNs

The proposed work aims to advance the fundamental understanding of multiple technical issues faced in enabling flexible end-to-end management of cloud-supported mobile applications. Methods are needed to (re)implement applications so that their software architectures can reconfigure in response to changes in requirements as the environment changes, and to allow for runtime re-factoring of components for execution locally or remotely. Virtual networking techniques are needed to enable seamless off-loading of computation from a device to remote resources possibly provided by multiple clouds. In addition, both software adaptation and network configuration must be done on-demand. The determination of when and how to adapt must be model-based, i.e. done on the basis of accurate models of software architectures, users, applications and the environment, and monitored system state and desired behaviors; the complexity and real-time nature of this process needs user-centered model-based autonomic solutions. They include the user in the adaptation loop so to optimize for tradeoffs between user satisfaction and other criteria, such as power in the client and server. Interoperability and portability considerations call for the use of new or improved virtualization approaches that are generally applicable to decouple application deployments from physical systems.
