CoseDroid: Effective Computation- and Sensing-Offloading for Android Apps

Smartphone applications are becoming increasingly popular. However, these applications can suffer limited power budgets or malfunctioned sensing issues from their host devices. Computation offloading addresses this issue by delegating local computation workloads to remote servers. In this paper, we present Cose Droid, a framework that supports dynamic computation- and sensing-offloading across different Android mobile devices. This enables Android applications to virtually "borrow" computation or sensing resources from other devices. We experimentally evaluated Cose Droid with real-world Android applications. The experimental results confirmed Cose Droid's effectiveness in on-demand offloading, as well as supporting sensor variety and spontaneous sensing recovery.
