Everywhere, electric power is needed for a variety of functions and tasks. Creating electric power through renewable resources, like solar energy, is a practical way to solve a lot of issues. Typically, photovoltaic modules use solar radiation to generate electricity. To guarantee maximum usage or optimal efficiency, a photovoltaic system must be equipped with a maximum power point tracking converter (MPPTC). In this paper, a DC to DC forward converter is chosen to function as MPPTC. For MPPTC under uniform sun irradiances, a variety of traditional methods are available, such as incremental conductance, perturb, and observe. However, trees, shade, dust, birds, clouds, and other factors will cause photovoltaic modules - of which many are coupled to make a power production unit - to receive non-uniform irradiances. The system enters a partial shading condition (PSC) as a result of this event. Conventional algorithms may be failed to approach the maximum utilization point to increase energy extraction under PSC. Therefore, to operate the power unit at its optimal usage under the situation of PSC, an optimization method is needed. In this study on MPPTC, an optimization method called the “Modified Osprey optimization Algorithm (MOOA)” is designed to gather more energy during PSCs. This research also compares MOOA, Modified Invasive Weed optimization (MIWO), Modified Grey Wolf optimization (MGWO), and whale optimization Algorithm (WOA). OPALRT technology is used to create the Hardware-in-the-Loop, which gathers diverse outcomes for analysis under different operations.

Underwater Wireless Sensor Networks (UWSNs) face significant communication and performance challenges due to their harsh and dynamic underwater environment. To address these issues, efficient and robust communication models are essential. This research proposes an energy-aware deployment approach and introduces the Controlled Transmission enhanced by hybrid model scheme with Differential Evolution, whale optimization, and Chaotic Adaptation (CT-DEWCA) for relay selection. This model enhances node placement by implementing a “strategic dual transmission” approach, which employs CT for short-distance data transfer and utilizes the DEWCA hybrid algorithm to select optimal relay nodes for long-distance communication. The strategy optimizes energy allocation between storage and regular nodes. Simulations show that the CT-DEWCA model outperforms conventional Vector-Based Forwarding (VBF), Hop-by-Hop Vector-Based Forwarding (HH-VBF), Depth-Based Routing (DBR), and, with recent work, Energy-Efficient Artificial Fish Swarm-based Clustering Cognitive Intelligence Protocol (EAFSCCIP). The results show an improvement by an average of 5.4% in packet delivery ratio, 20% reduction in cumulative energy consumption, 6% increase in throughput, and 12% lower packet-loss rate on average compared to the other protocols. This research offers a robust solution for enhancing UWSNs performance and longevity by addressing critical energy efficiency issues and reliable data transmission in underwater environments. The proposed approach demonstrates the utility and potential of bio-inspired optimization techniques to tackle the unique challenges of underwater communication networks.

Utilizing cloud-edge technological advances offers substantial opportunities for resource administration, effectiveness, and financial savings. These characteristics have promoted consumer and enterprise usage of the smart integrated cloud-edge model in the Internet of Things (IoT). In integrated cloud-edge computation, among the major difficulties is human resource management (HRM). Choosing the best capabilities depending on Quality of Service (QoS) considerations is a crucial and significant problem in IoT settings as software and hardware assets in the edge context are allotted for reacting to human demands. In the sense that system effectiveness rises and reaction duration falls with appropriate resource choosing, allotment, and surveillance, HRM may be viewed as an NP issue. This work uses the whale Optimized Technique in cloud-edge computation to offer an optimal framework for the HRM issue. According to empirical outcomes, the suggested framework outperformed the additional meta-heuristic techniques in two distinct situations: shortest response duration, allocation expenses, and growing proportion of HRs allotted.

The state of the water has a significant impact on human health, ecosystems, and economic activity. For efficient environmental management, water quality metrics must be tracked and predicted. Water quality is a crucial environmental health indicator since it directly affects biodiversity, ecosystem stability, and human well-being. Accurate prediction of the Index of Water Quality (WQI) and the Classification of the quality of water (WQC) is essential for effective management of water supplies, early pollution identification, and the guarantee of clean water for a range of applications. The traditional methods often lack the accuracy and flexibility required for complex water systems. Conventional techniques frequently suffer from noise and fluctuation, which causes judgments to be inaccurate. This work presents a novel method: a dynamic slimmable network with an Emperor Penguin optimizer (DSN-EPO) for forecasting the Water Quality Index (WQI), the Square Root Sage Husa Adaptive Robust Kalman Filter (SR-SHARKF) for preprocessing, and the beluga whale optimization algorithm for feature selection. The most important elements influencing the quality of the water are identified by the beluga whale algorithm, while the SR-SHARKF efficiently reduces noise and improves data accuracy. The forecasting model is then constantly optimized by the DSN-EPO by utilizing the slimmable architecture to achieve equilibrium between computational efficiency and precision. Comparing this integrated methodology to more conventional methods, predicting performance is enhanced. The proposed method performs outstandingly, with 99% of the major metrics met.

The safe and effective functioning of lithium-ion (Li-ion) batteries depends on accurate State of Charge (SOC) prediction. In order to increase the accuracy of SOC estimation, this study suggests a unique hybrid model that combines the whale optimization Algorithm (WOA) with Enhanced Deep Neural Networks (EDNN). Complex, non-linear connections between battery characteristics including voltage, current, temperature, and time are well captured by the EDNN. WOA ensures improved generalization and quicker convergence by optimizing the EDNN hyperparameters. Real-world battery datasets are used to validate the model, and metrics such as Mean Absolute Error (MAE) and Root Mean Square Error (RMSE) are used to assess performance. According to the results, the EDNN-WOA hybrid model improves reliability under a range of operating situations by drastically lowering prediction errors when compared to conventional machine learning techniques. This method shows how cutting-edge deep learning and metaheuristic optimization approaches can be combined to improve the performance and longevity of Li-ion batteries and aid in the creation of intelligent battery management systems.

This study proposes an AI-ADP system for the Smart Grid (SG) framework to address the increasing vulnerabilities to cyberattacks and threats in the advanced digital grid system. The AI-ADP system is an Artificial Intelligence (AI)-based Attack Detection and Prevention (ADP) tool that uses a cryptography-based recommendation system to ensure data security and integrity. The system is divided into two stages: trap detection and snare prevention. The WOA-ANN (whale optimization Algorithm-Artificial Neural Network) tool is used for trap detection and classification, while SHA-512 is used for secure communication. Evaluation results show that the proposed AI-ADP system outperforms existing methods and achieves a high accuracy of 99.12% in detecting and preventing cyberattacks in the SG framework.

Given that Orthogonal time frequency space (OTFS) modulation provides high robustness to Doppler shifts, its integrated sensing and communications (ISAC) has attracted more attention. In this work, we investigate the fractional delay-Doppler (DD) estimation problem for the OTFS-based ISAC system. We establish a two-dimensional (2D) correlation structure with superimposed multiple frames and propose an efficient Maximum Likelihood algorithm based on multi-frame superposition (ML-MFS) that significantly reduces computational complexity. To further improve the estimation accuracy in multi-target scenarios, we develop an estimation method based on the whale optimization algorithm, named WOA-MFS. Simulation results demonstrate that both algorithms markedly reduce complexity, with the WOA-MFS demonstrating superior estimation accuracy.

As the key economic index of electricity market, electricity price is directly affected by the change of supply and demand balance. However, there are often various noises in the actual electricity market data, which makes the detection of electricity price anomalies difficult. Through effective noise suppression and signal enhancement, this paper proposes a method called PRO-WOA, which combines whale optimization algorithm and wavelet transform to achieve noise suppression and signal enhancement in power price anomaly detection. Taking the actual power trading data of a province in 2022 as the research object, we conducted comparative experiments on different models. The results show that PRO-WOA performs well in forecasting accuracy and real-time performance, significantly outperforming other comparison models.

Workflow scheduling in cloud-fog environment aims to optimize task allocation, execution time, and resource management. The complexity and dynamic nature of tasks and resources make finding an optimal workflow scheduling algorithm challenging. To address these limitations, this study introduces a Hybrid Particle Swarm optimization Algorithm-whale optimization Algorithm (HPWOA). While Particle Swarm optimization (PSO) struggles with slow convergence and high-dimensional search spaces, whale optimization Algorithm (WOA) faces difficulties in irregular search spaces and inconsistent convergence rates. By integrating PSO and WOA, HPWOA mitigates local optimization issues and enhances optimisation efficiency. The primary objective of this work is to minimise Total Execution Cost (TEC). To validate HPWOA, a comparative analyses against PSO, WOA, and HPWOA across three scientific workflows with increasing test cases has been performed. The results demonstrate that the proposed algorithm is 1.92% better than PSO and 9.60% better than WOA in terms of TEC. The paper highlights HPWOA's effectiveness in improving workflow scheduling and identifying the optimal workflow configurations for cloud-fog environments.
