“…The use of the classic FLS architecture leads to non-adaptive solutions, while using the other two architectures, reinforcement learning-based real-time adaptive architecture and simple real-time adaptive architecture, result in adaptive solutions.

FL-based decision making solutions in VNs include: routing protocols, clustering algorithms, handover schemes and data aggregation mechanisms.…”
