🤖 AI Summary
To address the stringent requirements of ultra-low latency, high bandwidth, and intelligent resource management for virtual reality cloud gaming (VR-CG) in 6G networks, this paper proposes a multi-stage collaborative resource allocation framework encompassing user association, edge-based game engine deployment, and attention-aware wireless scheduling. We introduce a visual-attention-driven, user-centric Quality-of-Experience (QoE) model; design a three-stage decoupled optimization architecture with lightweight heuristic algorithms; and pioneer the integration of adaptive resolution/frame-rate control—subject to motion-to-photon latency constraints—into the scheduling decision process. By synergistically leveraging 6G network slicing, multipath transmission, and QoE-oriented dynamic video encoding, our approach achieves, under dataset-driven evaluation: a 50% improvement in QoE, a 75% reduction in communication resource consumption, a 35% decrease in operational cost, an average optimality gap of only 5%, and sub-0.1-second solution time for large-scale scenarios.
📝 Abstract
Virtual Reality Cloud Gaming (VR-CG) represents a demanding class of immersive applications, requiring high bandwidth, ultra-low latency, and intelligent resource management to ensure optimal user experience. In this paper, we propose a scalable and QoE-aware multi-stage optimization framework for resource allocation in VR-CG over 6G networks. Our solution decomposes the joint resource allocation problem into three interdependent stages: (i) user association and communication resource allocation; (ii) VR-CG game engine placement with adaptive multipath routing; and (iii) attention-aware scheduling and wireless resource allocation based on motion-to-photon latency. For each stage, we design specialized heuristic algorithms that achieve near-optimal performance while significantly reducing computational time. We introduce a novel user-centric QoE model based on visual attention to virtual objects, guiding adaptive resolution and frame rate selection. A dataset-driven evaluation demonstrates that, when compared against state-of-the-art approaches, our framework improves QoE by up to 50%, reduces communication resource usage by 75%, and achieves up to 35% cost savings, while maintaining an average optimality gap of 5%. Our proposed heuristics solve large-scale scenarios in under 0.1 seconds, highlighting their potential for real-time deployment in next-generation mobile networks.
