Task scheduling in the IoT is pivotal for optimizing resource utilization, minimizing latency, and enhancing the overall system’s performance. This research proposes a novel method called QTE-IoT, standing for a Q-learning-based task scheduling scheme to enhance energy consumption and QoS in IoT environments. QTE-IoT commences by categorizing tasks into three classes: time-sensitive tasks, security tasks, and normal tasks. This classification is achieved using a multi-layer perceptron artificial neural network. Subsequently, time-sensitive tasks are offloaded to the fog layer and scheduled using the proposed African Vulture Algorithm combined with Q-learning, which we designate as QAVA. Security tasks are offloaded to the private cloud, while normal tasks are offloaded to the public cloud. For task scheduling in private and public cloud environments, QTE-IoT employs a proposed enhanced version of Artificial Rabbits Optimization integrated with the Q-learning algorithm, known as QARO. Additionally, the QTE-IoT method incorporates a monitoring agent to oversee resource workload, thereby preventing congestion and delays. Simulation results on instances of the HCSP benchmark dataset demonstrate that QTE-IoT outperforms other state-of-the-art methods in various performance metrics. QTE-IoT achieves significant improvements compared to other methods and algorithms, including a 6–12 % reduction in energy consumption. Furthermore, QTE-IoT exhibits substantial improvements in load imbalance (42–79 %), response time (25–40 %), and deadline satisfaction (6–39 %) compared to existing approaches.</div></div>","PeriodicalId":48686,"journal":{"name":"Sustainable Computing-Informatics & Systems","volume":"48 ","pages":"Article 101247"},"PeriodicalIF":5.7,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145520138","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}

This paper introduces a Continual Learning-Based Regression Testing (CLRT) framework specifically designed for scalable VLSI verification across hierarchical abstraction levels such as logic, design, and chip. The framework overcomes the drawbacks of static test models through the stationary learning techniques, which are ingrained in the framework, and the ability to continuously learn and adjust the test strategy against every new design change and test results. To enforce the above property, our approach is based on a two-layer learning mechanism: the first layer is a supervised learning model with historical test outcomes for detecting regression-sensitive regions in the design space through the second one (an online continuous learning module) that can sequentially adapt to new data without catastrophic forgetting. This allows the system to remember learned test behavior and simultaneously adapt to changing design configurations. A hybrid feature selection mechanism is utilized for the extraction of the effective parameters, which should be extracted from design-level netlist, logic-level signals traces and fault logs at the chip bubbled status for a thorough cross-layer coverage. Experimental verification was performed on ITC-99 and Open Cores VLSI benchmark designs. The proposed CLRT framework achieved a remarkable reduction of 28.6 % in test redundancies and improvements of 35.2 % in fault detection accuracy when comparing to the traditional regression suites. Moreover, the system maintained a stable performance across variations of design, and this made it robust in dynamic testing conditions.

Among them, mobile EV energy storage, particularly in the context of e-shared mobility, offers a flexible and scalable solution for load frequency control in modern EIP-MGs. This study presents a novel framework for sustainable transient frequency management using a fractional-order computing-based hybrid cascade controller, TFOID–3DOF–TID (Tilted Fractional-Order Integral and Derivative with Three Degrees of Freedom), optimized via the Crested Porcupine Optimizer (CPO).

The evaluations are structured around frequency-domain design criteria based on integral error metrics, including squared and absolute formulationsaimed at analyzing efficiency, sensitivity, adaptability, robustness, stability, and computational burden. The proposed control scheme, featuring the TFOID and 3DOF-TID controllers, is evaluated in comparison with validated metaheuristic-based algorithms. Simulation results demonstrate that the CPO-based TFOID–3DOF–TID controller consistently outperforms other schemes, with improvements including a 22 %–48 % reduction in settling time, a 25 %–55 % decrease in undershoot, and a 30 %–60 % reduction in overshoot across varying scenarios. Additionally, Bode plot evaluations confirm superior phase margins and damping characteristics, while robustness margins improve by up to 60 %, affirming the controller’s resilience under non-ideal operational conditions.
