Abstract

The explosion of user generated data along with the evolution of web 2.0 applications (e.g. social networks, blogs, podcasts, etc.) has resulted in a tremendous demand for storage. With cloud computing posing as a possible all-in-one solution, "storage clouds" focus on providing distributed storage capability. We discuss the creation of a storage cloud using edge devices, based on Peer-to-Peer resource provisioning. In this approach, mobile phones, PCs/Media Centers, Set-top-boxes, modems and networked storage devices can all contribute as storage within these storage clouds. Combining all end-user edge devices may result in a scalable, very flexible storage capability that keeps the data comparatively close to the user, increasing availability, while reducing latency. This work addresses the issue of Quality of Service (QoS)-aware scheduling in a P2P storage cloud, built with edge devices by designing an optimization scheme that minimizes energy from a system perspective and simultaneously maximizing user satisfaction from the individual user perspective.
