Description

The framework to support faulttolerant and energyefficient remote storage and processing under a dynamic network topology. It aims for applications that require energyefficient and reliable distributed data storage &processing in dynamic network. The koutofn reliability mechanism is integrated into distributed computing in mobile cloud.For mobile devices deployed in dynamic networks (i.e., with frequent topology changes because of node failure/unavailability and mobility as in a mobile cloud), however, challenges of reliability and energy efficiency remain largely unaddressed. To the best of our knowledge, we are the first to address these challenges in an integrated manner for both data storage and processing in mobile cloud, an approach we call koutofn computing. In our solution, mobile devices successfully retrieve or process data, in the most energyefficient way, as long as k out of n remote servers are accessible. Through a real system implementation we prove the feasibility of our approach. Extensive simulations demonstrate the fault tolerance and energy efficiency performance of our framework in larger scale networks
