FUSION: Forecast-Embedded Agent Scheduling with Service Incentive Optimization over Distributed Air-Ground Edge Networks

Abstract: We investigate a forecasting-driven, incentive-compatible service provisioning framework for distributed air-ground integrated edge networks under human-machine coexistence. We consider hybrid players where the computing capacity of edge servers (ESs) are augmented by vehicular-UAV agent pairs (AgPs) that can be proactively dispatched to overloaded hotspots. Unique key challenges should be addressed: highly uncertain spatio-temporal workloads, spatio-temporal coupling between road traffic and UAV capacity, forecast-driven contracting risks, and heterogeneous quality-of-service (QoS) requirements of human users (HuUs) and machine users (MaUs). To cope with these issues, we propose FUSION, a two-stage framework that tightly couples service demand prediction, agent deployment, and task scheduling. In the offline stage, a Pro-LNN module performs intelligent multi-step spatio-temporal demand forecasting at distributed ESs, whose outputs are exploited by an enhanced ant colony optimization-based routing scheme (eACO-VRP) and an auction-based incentive-compatible contracting mechanism (Off-AIC^2), to jointly determine ES-AgP contracts and pre-planned service routes. In the online stage, we formulate congestion-aware task scheduling as an potential game among HuUs, MaUs, and heterogeneous ES/UAV providers, and devise a potential-guided best-response dynamics (PG-BR) algorithm that provably converges to a pure-strategy Nash equilibrium. Extensive experiments on both synthetic and real-world traces show that FUSION significantly improves social welfare, latency, resource utilization, and robustness compared with state-of-the-art baselines.
