Abstract: Under China’s “Dual-Carbon” strategic goal, reducing carbon emissions in computing centers has become a critical challenge. The increasing scale of data centers, particularly in the context of initiatives such as “East Data, West Computing,” necessitates new approaches that jointly optimize computing efficiency and carbon footprint. This paper aims to address this challenge by proposing a novel carbon-computing coupling optimization framework and a green scheduling system designed to minimize the carbon emissions associated with computational tasks while maintaining system robustness. We first establish a carbon efficiency dynamic equilibrium equation and introduce the concept of virtual carbon flow to model the carbon footprint of computing tasks. Based on this modeling, we develop a deep reinforcement learning (DRL) based scheduler that dynamically migrates tasks to low-carbon nodes. In addition, we integrate a digital twin platform that preemptively simulates failure scenarios to enhance system robustness and resilience. Experimental results in simulated “East Data, West Computing” scenarios demonstrate the effectiveness of the proposed approach. The system reduces carbon emissions per unit of computing power by 18%, improves the energy efficiency ratio in western nodes by 35%, and decreases the Mean Time to Recovery (MTTR) from 2 hours to 15 minutes. These findings validate the potential of carbon-computing coupling optimization in achieving both sustainability and reliability goals for large-scale computing centers.

Abstract: Cloud computing has fundamentally transformed how computing resources are delivered, offering scalable, on-demand, and cost-efficient services to users across diverse domains. Despite these advantages, the inherently dynamic and heterogeneous characteristics of cloud environments create persistent challenges in achieving efficient workload distribution and optimal resource utilization. When load balancing mechanisms are ineffective, systems experience increased response times, underutilized or overburdened resources, and an overall decline in Quality of Service (QoS), which directly affects user satisfaction and system reliability. To address these issues, this study proposes a comprehensive conceptual framework designed to improve load balancing and resource optimization in cloud infrastructures. The framework emphasizes the integration of multiple components, including advanced task scheduling techniques and dynamic load balancing strategies that can adapt to fluctuating workloads in real time. By leveraging these mechanisms, the system can distribute tasks more evenly across available resources, minimizing bottlenecks and enhancing performance efficiency. A key aspect of the framework is the incorporation of emerging computing paradigms such as fog computing. This approach extends cloud capabilities closer to the data source, thereby reducing latency and improving response times, especially for time-sensitive applications. Additionally, the framework adopts intelligent optimization techniques, combining hybrid metaheuristic algorithms with machine learning models to effectively manage complex and unpredictable workloads. These methods enable the system to learn from past patterns, predict future demands, and make informed decisions regarding resource allocation and task scheduling. The framework also highlights the importance of evaluating system performance using critical metrics such as throughput, response time, makespan, and scalability. These indicators provide a comprehensive understanding of how well the system performs under varying conditions and workloads. By analyzing these metrics, researchers and practitioners can identify areas for improvement and refine the system for better efficiency. Overall, the proposed framework offers a flexible, extensible, and forward-looking foundation for enhancing cloud resource management. It is particularly valuable for guiding future research focused on developing deep learning-driven hybrid optimization models that can further improve adaptability, efficiency, and performance in increasingly complex cloud environments.

Abstract: This paper presents a comprehensive, mixed-methods investigation into the performance attenuation of Wireless Mesh Networks (WMNs) during the transition from simulated environments to real-world deployments within the unique context of higher education institutions in emerging economies. Using the University of Cape Coast (UCC), Ghana, as an in-depth case study, we quantify and analyse the significant discrepancies between NS3-based simulation forecasts and empirical field measurements across four critical dimensions: scalability, redundancy, coverage, and Quality of Service (QoS). Our findings reveal that synergistic environmental factors, including concrete-dominated infrastructure, coastal humidity, and dense foliage, attenuate theoretical network performance by up to 50%. Furthermore, while redundancy mechanisms demonstrate robustness in simulations, they are critically undermined by recurring operational constraints such as Fiber cuts, power instability, and limited maintenance capacity, reducing practical Uptime from a simulated 99.9% to 92.5% in basic setups. Beyond identification, this study contributes a novel, multi-tiered framework designed to mitigate this attenuation gap. This framework advocates for phased, pilot-based deployments, environment-aware network design incorporating UAV-assisted profiling, and a hybrid validation model that continuously integrates real-world data. The paper concludes with actionable, context-sensitive recommendations for researchers, network architects, and institutional policymakers operating in resource-constrained settings, emphasising cost-effective resilience and user-centric alignment of quality of service.
