| 2026 | Language-Guided Game-Theoretic Fairness in Web-Enabled Energy NetworksabstractWeb platforms are reshaping resource allocation in distributed energy networks globally, from off-grid communities to lunar bases. Algorithmic decision-makers face the fundamental challenge of fairly distributing scarce resources among heterogeneous stakeholders. Traditional approaches assume complete rationality with perfect information and unlimited computation, yet distributed networks only permit local observation, requiring fairness to emerge from individual strategic interactions. Centralized optimization fails due to exponential complexity, rule-based methods cannot adapt to disruptions, and existing platforms translate economic inequality into energy access inequality. Recognizing the unattainability of complete rationality necessitates bounded rationality: pursuing provably convergent satisficing solutions under incomplete information and limited computation, translating natural language ethics into computable constraints, and designing incentives so self-interested behavior satisfies fairness at equilibrium. We propose a unified semantic-game-distributed framework. Large language models map ambiguous ethical principles into game-theoretic parameters through semantic parameterization, with contrastive learning ensuring semantic consistency and temporal stability. A two-layer Stackelberg game implements incentive design: the platform signals through differentiated pricing while nodes optimize locally, enabling fairness to emerge from equilibrium. Distributed asynchronous iteration achieves global convergence through local communication, with cognitive models adaptively adjusting step sizes and differential perturbation preserving privacy. Theoretical analysis establishes equilibrium existence and convergence guarantees, while extreme scenarios validate robustness under information scarcity and high uncertainty.

| 2026 | Addressing the Computational Divide in Vehicular Networks: A Lifecycle-Aware Task Offloading Framework With Deep Reinforcement LearningabstractThe Internet of Vehicles (IoV), a critical large-scale Internet of Things (IoT) application, faces a fundamental sustainability challenge stemming from the lifecycle mismatch between long-duration vehicular hardware and rapidly evolving software. This mismatch creates a widening “computational divide,” where aging vehicles with limited onboard resources cannot support modern data-intensive applications, thereby fragmenting the ecosystem and undermining its collective intelligence. To address this systemic issue, this paper proposes a novel lifecycle-aware task offloading framework. Instead of treating vehicular heterogeneity as a static liability, our framework transforms it into a dynamic, cooperative resource-sharing opportunity. At the core of this framework is a Deep Reinforcement Learning (DRL) agent deployed on resource-constrained vehicles, which orchestrates task offloading decisions to co-optimize for latency and energy consumption. A key innovation is the “Performance Capacity” metric, a multi-dimensional and predictive state assessment mechanism. This metric enables informed decision-making by intelligently fusing a vehicle’s static hardware profile, its dynamically predicted future workload, and its cooperation reputation. Furthermore, an integrated credit-based incentive mechanism is designed to ensure the long-term economic viability of this cooperative ecosystem. Simulation results demonstrate that our framework significantly reduces task latency and energy consumption, particularly under high-load conditions, offering a scalable and sustainable solution for the continuous evolution of heterogeneous IoV systems.
