GTTC: A Low-Expenditure IoT Multi-Task Coordinated Distributed Computing Framework with Fog Computing

As an important scenario under the 5G, the Internet of things (IoT) is undertaking countless computing tasks, which are obtained from real life. However, for IoT devices, due to the limited computing resource and battery capacity, it is difficult to cope with the diversified incoming computing tasks. To this end, this paper studies the IoT task computing expenditure problem with the assistance of fog computing and cloud center. We firstly propose a game theoretic task computing framework (GTTC) to ease the competition of multi-nodes by taking into account the expected benefit of each computing node. Then, we put forward the concept of tendency-oriented priority (TOP) to coordinate the scheduling order between multi-tasks of fog computing node for further reducing the expenditure. Finally, the effectiveness of the proposed mechanism is verified by sufficient experimental simulations in terms of a wide set of performance metrics.
