Because even the smallest faults occurring on growing power lines can impact the grid, rapid fault detection, classification, and subsequent repair are crucial. In this study, a new Machine Learning approach based on the Autogluon framework is proposed for rapid fault detection and high-accuracy classification of transmission line faults. Three different methods are employed within the Autogluon framework, and the results are evaluated and compared using ROC analysis. The first method uses the original dataset containing 7861 data points obtained from the open-source Kaggle platform. The second approach adds statistical properties of current and voltage values (mean, standard deviation, and range) to the original dataset. The third method uses the SMOTE algorithm to generate synthetic data and increase the data size to address the imbalance in the number of fault classes in the dataset. The proposed method demonstrates the critical role of data processing and feature engineering in optimizing classification performance and achieving the most accurate diagnosis for multi-label fault classification. The numerical results compared with the literature show that the proposed method is promising for practical applications.</div></div>","PeriodicalId":48686,"journal":{"name":"Sustainable Computing-Informatics & Systems","volume":"50 ","pages":"Article 101310"},"PeriodicalIF":5.7,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146122686","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}

However, these networks face challenges such as limited energy resources, frequent topology changes, and performance degradation caused by node misbehavior. Existing protocols like AODV have significant limitations, including a lack of energy awareness, an inability to detect malicious behavior, and the absence of secure transmission mechanisms. These weaknesses lead to rapid energy depletion and increased vulnerability to attacks. To address these issues, this paper proposes a novel energy-aware unobservable routing protocol. The new protocol introduces custom packet types, such as PT_NID, PT_GID, and PT_CREV, to monitor the real-time behavior of neighboring nodes and to manage route revocation. Trust evaluation is performed using packet-forwarding ratios, and false positives are detected. Additionally, the protocol checks each node's residual energy before forwarding data to the next node. To ensure data confidentiality, elliptic curve cryptography (ECC) is employed, providing robust encryption while reducing resource consumption. ECC is particularly beneficial for MANET devices with limited resources, as it offers strong security with lower overhead. Simulations conducted using NS2 software demonstrate that the proposed model outperforms the traditional AODV protocol in terms of network lifetime, packet delivery ratio, throughput, and delay, particularly under conditions of node mobility and varying node density. Overall, the proposed protocol offers a more robust, scalable, and secure solution for MANET environments compared to existing protocols.</div></div>","PeriodicalId":48686,"journal":{"name":"Sustainable Computing-Informatics & Systems","volume":"49 ","pages":"Article 101285"},"PeriodicalIF":5.7,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145840587","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 modern Energy services in residential buildings, especially those using combined cooling, heating, and power (CCHP) systems, are particularly important in meeting these demands. Accordingly, this study focuses on day-ahead energy management in a smart CCHP grid with the participation of hybrid energy storage systems and optimal energy consumption by consumers in smart residential buildings. The energy management is modeled by a multi-level and multi-objective optimization approach considering demand response strategies (DRSs). The DRSs include electrical demand shifting of power consumption, and self-generation of power, and gas storage systems. The electrical demand shifting strategy is implemented in the first level optimization, subject to electricity pricing traffic to minimize consumers’ bills. Also, minimizing consumers’ bills in the second level optimization is done by power and gas storage systems via the local self-generation (LS-G) strategy, subject to electricity and gas prices in the energy market. In the third level optimization, multi-objective functions like minimizing operational costs, maximizing flexibility and minimizing power losses are implemented. In the proposed optimization approach, optimized energy consumption in the first and second levels is considered in the third level optimization. The proposed optimization approach for all levels is solved by using General Algebraic Modeling System (GAMS) software. In the following, solving multi-objective optimization approach in the third level is carried out by enhanced epsilon-constraint method. Also, Shannon Entropy decision making method is proposed for determining optimal solution in third level for multi-objective functions and Pareto front solutions. Finally, the findings show the optimal results of the objectives at each level and highlight consumer involvement through a comparative analysis via various case studies.

This paper proposes an adaptive hybrid framework that integrates fuzzy logic with Deep Q-Network (DQN) reinforcement learning to optimize task scheduling and resource allocation in heterogeneous and dynamic environments. The model is designed to maintain service quality while remaining compatible with limited computational resources. The scheduling problem is first formulated as a multi-objective optimization model aimed at jointly minimizing delay, energy usage, and makespan. A fuzzy inference system is then employed to evaluate task attributes such as deadline, delay sensitivity, and data volume in order to assign priority levels. Based on this prioritization, the DQN agent dynamically allocates resources by interacting with the environment and learning from feedback. The proposed framework was evaluated on scenarios involving 500–2000 tasks under varying resource conditions, and its performance was benchmarked against conventional algorithms. Experimental results demonstrate that the proposed method achieves, on average, a 27.8 % reduction in execution time, a 29.6 % decrease in scheduling delay, an 18 % reduction in energy consumption, and a 21.4 % improvement in makespan.

To overcome these constraints, this work proposes an energy-efficient unified computing framework where communication networks, HPC clusters, and AI orchestration operate as a tightly coupled ecosystem.
