Traditional strategies such as full-line reinforcement are often impractical for islands due to the extremely high investment cost. This paper proposes a reliability-driven planning framework for microgrids under various failure scenarios, introducing Soft Open Points (SOPs) as flexible interconnection devices. Line failure rates are estimated based on component health indices and submarine cable lengths, and a scenario-based mixed-integer linear programming (MILP) model is developed to jointly optimize distributed energy resource scheduling and SOP siting and sizing. The proposed framework is validated on the Orkney Islands microgrid. Case studies demonstrate that optimal SOP deployment can reduce load shedding and renewable curtailment, improve voltage profiles, and lower total operational costs by over 50%, without the need for large-scale infrastructure upgrades. The results provide practical insights into enhancing the reliability and cost-effectiveness of island microgrids under reliability constraints.","PeriodicalId":13268,"journal":{"name":"IEEE Transactions on Sustainable Computing","volume":"11 3","pages":"240-252"},"PeriodicalIF":3.9,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148171908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The scalability and adaptability features of cloud computing are efficiently enable resource utilization and continuous data exchange in dynamic and heterogeneous environments. However, the increasing demand for cloud services has raised the energy consumption of cloud data centers, which has a critical environmental impact. Therefore, sustainable resource management tactics have become crucial in today’s world. Dynamic Virtual Machine (VM) consolidation is one of the major tactics for sustainable resource management in the green cloud computing environment. Herein, a novel dynamic Energy-Aware Cosine Similarity Learning Network (ECSLN) is proposed to predict the overutilized host. Further, an Impact Factor-Based VM Selection (IFBVMS) method is proposed to select VMs for migration, and an ECSLN-Packed Placement method for VM placement into hosts. The main aim of the proposed VM consolidation is to maximize energy efficiency while preserving compliance with Service Level Agreements (SLAs) for sustainable environments. The experimental evaluation using real-world traces like PlanetLab, Bitbrains, and Alibaba Cluster 2020 workload validates that the proposed VM consolidation methods significantly reduce energy consumption and SLA violation compared to the existing methods for sustainable environments. The evaluation shows that the proposed ECSLN-based consolidation framework enables green cloud infrastructure by intelligently balancing energy consumption, SLA violation, and performance of cloud data centers.","PeriodicalId":13268,"journal":{"name":"IEEE Transactions on Sustainable Computing","volume":"11 2","pages":"123-134"},"PeriodicalIF":3.9,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147606290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data centres now account for an estimated 2% to 4% of global electricity consumption. Although various best practices and key performance indicators (KPIs) have been developed to mitigate this impact, creating a comprehensive framework for evaluating the environmental sustainability of data centres remains challenging. Existing certification schemes, such as Leadership in Energy and Environmental Design (LEED) and the Building Research Establishment Environmental Assessment Method (BREEAM), were originally designed for traditional building infrastructure and are increasingly applied to data centres. However, these frameworks primarily focus on building-related aspects, inadequately addressing the unique mechanical, electrical, and IT dimensions critical to data centres.

The integration of EHML with XAI is introduced for the first time in the crop and fertilizer recommendation system. This work focuses on crop recommendations solely based on the micro and macro nutrients present in the soil, an aspect that has been largely overlooked till date. Based on various hybrid machine learning (HML) models such as CatBoost and Extreme Gradient Boosting, optimized with Sparrow Search Algorithm, Phasor Particle Swarm Optimization, and Grey Wolf Optimization, crops are recommended with accuracy ranging from 99.64% to 99.87%. The state-of-the-art work is also compared with hybrid models optimized with standard optimizers, such as Genetic Algorithm and Particle Swarm Optimization. To reveal critical drivers of crop selection and enhance the interpretability of the best-performed models, XAI algorithms (Local Interpretable Model Explanation and SHapley Additive exPlanations) are employed. The best-performing eco-friendly model is also recommended based on low <inline-formula><tex-math>${CO}_{2}eq$</tex-math></inline-formula> emissions and electricity consumption, helping to preserve natural resources. Additionally, a farmer-friendly web application is developed to provide instant crop and fertilizer recommendations for sustainable agriculture.

However, selecting key knowledge and effectively transferring it from teacher to student remains a challenging problem. In this work, we propose an efficient Cluster-based Knowledge Distillation (CKD) dedicated to aligning the student model with the teacher model in terms of both sample relations and class centers. Specifically, CKD first determines the key sample relations based on the similarities between the sample features extracted by the teacher and their cluster centers generated by existing clustering algorithms. Then, CKD effectively transfers the knowledge of the above relations from the teacher to the student by designing a cluster-based relation distillation loss. Finally, CKD further improves the quality of the student's class centers by constructing a center loss between the above representative cluster centers and the student's class centers. We validate the proposed CKD on multiple face benchmarks. For example, CKD improves the baseline student performance from 91.95% to 94.20% on MegaFace and consistently outperforms recent competitive distillation methods on multiple benchmarks. These results demonstrate the effectiveness and superiority of CKD.","PeriodicalId":13268,"journal":{"name":"IEEE Transactions on Sustainable Computing","volume":"11 3","pages":"253-265"},"PeriodicalIF":3.9,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11456779","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148171756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their enormous size and processing requirements hinder deployment on constrained resources. To enhance efficiency, binarization and Early Exit (EE) have proved to be effective solutions. However, binarization may lead to performance loss as reduced precision affects gradient estimation and parameter updates. Besides, research on EE mechanisms is still in its early stages. To address these challenges, we introduce Binarized Early Exit Transformer (BEExformer), a first-of-its-kind selective learning-based transformer integrating Binarization-Aware Training (BAT) with EE for efficient and fast textual inference. Each transformer block has an integrated Selective-Learn Forget Network (SLFN) to enhance contextual retention while eliminating irrelevant information. The BAT employs a differentiable second-order approximation to the sign function, enabling gradient computation that captures both the sign and magnitude of the weights. This aids in 21.30 × reduction in model size. The EE mechanism hinges on fractional reduction in entropy among intermediate transformer blocks with soft-routing loss estimation. This accelerates inference by reducing FLOPs by 52.27% and even improves accuracy by 3.22% by resolving the “overthinking” problem inherent in deep networks. Extensive evaluation through comparison with the SOTA methods and various ablations across nine datasets covering multiple NLP tasks demonstrates its Pareto-optimal performance-efficiency trade-off.","PeriodicalId":13268,"journal":{"name":"IEEE Transactions on Sustainable Computing","volume":"11 2","pages":"98-110"},"PeriodicalIF":3.9,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147606312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although significant progress has been made in UAV-enabled architectures, persistent challenges remain due to stringent energy constraints, dynamic task demands, and the high-dimensional nature of multi-UAV coordination. This work seeks to optimize deadline-aware task quality in battery-constrained IoT networks using Mobile Edge Computing (MEC)-enabled UAVs, each assigned Core Tasks with strict deadlines and Supplementary Tasks to enhance quality when additional resources are available. Nevertheless, the joint optimization of UAV 3D trajectories, WET, and task scheduling under tight energy and deadline constraints introduces a dynamic and continuous decision-making challenge. To address this, we propose a novel multi-UAV framework built upon two key pillars: (i) a Beta-distributed policy network for modeling bounded, continuous control actions, and (ii) a multi-head attention-based critic for capturing inter-UAV interactions and global context. Accordingly, we formulate the problem as a multi-agent Markov Decision Process (MDP) and develop Beta-Attention Multi-Agent Proximal Policy Optimization (BA-MAPPO), a Deep Reinforcement Learning (DRL) framework based on Multi-Agent Proximal Policy Optimization. Extensive simulations demonstrate that BA-MAPPO substantially improves energy efficiency, task quality, and deadline compliance, outperforming existing baselines in dynamic IoT environments.","PeriodicalId":13268,"journal":{"name":"IEEE Transactions on Sustainable Computing","volume":"11 3","pages":"302-315"},"PeriodicalIF":3.9,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148171883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the second stage, between the day-ahead and intraday periods, an iterative algorithm is introduced to calculate the number of reserved servers, thereby mitigating the workload overload issues arising from workload uncertainty.
