Cooperative Federated Learning-Based Task Offloading Scheme for Tactical Edge Networks
Sungwook Kim · IEEE Access · 2021
In this study, we focus on the federated learning (FL) based tactical edge network platform to cooperatively operate computation-hungry tasks as efficiently as possible. Based on the incentive of FL model training, each individual device makes offloading decisions for their tactical tasks in resource-con-strained network environments. According to the ideas of two different bargaining solutions -weighted av-erage solution and constant elasticity substitution solution -edge server and IoT devices work together in a coordinated manner to approximate a well-balanced system performance. Therefore, we can reach an agree-ment while exploring the mutual benefits to leverage a reciprocal consensus between different viewpoints. The main novelty of our approach is to investigate the dual-interactive bargaining process based on the inter-dependent relationship between IoT devices and the tactical edge server. To the best of our knowledge, this is the first work that jointly considers different bargaining solutions to handle tactical edge-assisted task of-floading services. Based on the numerical simulation, it is demonstrated that the proposed approach can in-crease the system throughput, device payoff and device fairness up to 10%, 15% and 20%, respectively, in comparison with existing protocols.
