A mobile data offloading framework based on a combination of blockchain and virtual voting

Abstract

The emergence of mobile cloud computing enables mobile users to offload computation tasks to other resource-rich mobile devices to reduce energy consumption and enhance performance. A direct peer-to-peer connection among mobile devices to offload computation tasks can be a highly promising solution to provide a fast mechanism, especially for deadline-sensitive offloading tasks. The generic blockchain-based system might fail in such a scenario due to it being a heavyweight mechanism requiring high power consumption in the mining process. To address these issues, in this article, we propose a directed acyclic graph-enabled mobile offloading (DAGMO) algorithm. DAGMO model is empowered by traditional blockchain features and provides additional advantages to overcome the fundamental limitations of generic blockchain. A game-theoretic approach is used to model the interactions between mobile devices. The numerical analysis proves the proposed model to enhance the overall welfare of the participating nodes in terms of computation cost and time.
