CloneDoc: exploiting the cloud to leverage secure group collaboration mechanisms for smartphones

The limited battery of smartphones makes it hard for users to fully exploit their devices. Recent research considers offloading mobile computation to the cloud to improve efficiency and to extend battery life. We design Clone2Clone (C2C), a distributed p2p platform for software cloud clones of smartphones. Upon C2C we implement CloneDoc, a secure real-time collaboration system for smartphone users. We measure the performance of CloneDoc on a testbed of six Android smartphones and clones hosted on the Amazon cloud service and show that C2C based protocols can significantly improve battery-life compared to protocols that do not make use of C2C.
