Fair Allocation of Bandwidth At Edge Servers For Concurrent Federated Learning Processes

This paper explores concurrent FL processes within a three-tier system, with edge servers between edge devices and FL servers. A challenge in this setup is the limited bandwidth from edge devices to edge servers. Thus, allocating the bandwidth efficiently and fairly to support simultaneous FL processes becomes crucial. We propose a game-theoretic approach to model the bandwidth allocation problem and develop distributed and centralized heuristic schemes to find an approximate Nash Equilibrium of the game. Through rigorous analysis and experimentation, we demonstrate that our schemes efficiently and fairly assign the bandwidth to the FL processes and outperform a baseline scheme where each edge server assigns bandwidth proportionally to the FL servers’ requests that it receives. The proposed distributed and centralized schemes have similar performance.
