The Internet of Things (IoT) is a network of physical items implanted with software, sensors, etc., to link and exchange data with other devices. These devices vary in complexity from common household items to sophisticated industrial instruments. It would be challenging to choose an appropriate IoT service based on the requirements of the vast pool of accessible services with similar capabilities, given the growth of IoT-based service providers in the market. A suitable selection may be made using quality-of-service (QoS) parameters that characterize a service. IoT has several benefits over traditional communication systems. Also, it is a component of a safe and smart city system known as the Industrial Internet of Things (IIoT) which is particularly useful in the industrial field. However, it suffers from various issues such as high costs, energy consumption, and long delays. The production scheduling problem is one of the main issues in IIoT, and it is an NP-hard problem regarding cost and energy efficiency. Therefore, a meta-heuristic algorithm based on the elephant herd optimizationalgorithm is proposed to minimize resource costs, conversion costs, and the cost of continuous development delays. By combining the clan updating factor, separating operator, and the proposed algorithm, we created an effective and efficient method to solve the issue of production scheduling. Many experiments are performed to determine the performance of industrial environments. The outcomes demonstrate that the suggested technique can optimize planning and achieve cost reduction, efficient energy consumption, and latency decrease.

Optimal placement of drones is a very challenging problem and it belongs to the group of hard optimization problems for which swarm intelligence algorithms were successfully applied. This paper presents an implementation of the recent elephant herding optimization algorithm for solving the static drone location problem. The objective of the model applied in this paper is to establish monitoring of all targets with the least possible number of drones. In empirical tests we used two problem instances: one with 30 uniformly distributed targets, and one with 30 clustered targets. The simulation results show that the elephant herding optimization algorithm performs well in covering targets for both instances of the problem, especially considering the number of drones that were deployed.

Premature babies scream to make contact with their mothers or other people. Infants communicate via their screams in different ways based on the motivation behind their cries. A considerable amount of work and focus is required these days to preprocess, extract features, and classify audio signals. This research aims to propose a novel elephantherding Optimized Deep Convolutional Gated Recurrent Neural Network (EHO-DCGR net) for classifying cry signals from premature babies. Cry signals are first preprocessed to remove distortion caused by short sample times. MFCC (Mel-frequency cepstral coefficient), Power Normalized Cepstral Coefficients (PNCC), BFCC (Bark-frequency cepstral coefficient), and LPCC (Linear Prediction cepstral coefficient) are used to identify abnormal weeping through their prosodic aspects. The elephantherdingoptimization (EHO) algorithm is utilized for choosing the best features from the extracted set to form a fused feature matrix. These characteristics are then used to categorize premature baby cry sounds using the DCGR net. The proposed EHO-DCGR net effectiveness is measured by precision, specificity, recall, and F1-score, accuracy. According to experimental fallouts, the proposed EHO-DCGR net detects baby cry signals with an astounding 98.45% classification accuracy. From the experimental analysis, the EHO-DCGR Net increases the overall accuracy by 12.64%, 3.18%, 9.71% and 3.50% better than MFCC-SVM, DFFNN, SVM-RBF and SGDM respectively.

MIMO (Multi-input, Multi-output) systems are a key technology for achieving 5G wireless communications' performance goals. They achieve significant levels of various acquisition, consistency, and efficiency. Nonetheless, for more transmit antennas;more radio frequency (RF) chains are necessary, which may result in increased computational complexity and expenses. As a result, selecting the optimal transmit antennas is critical for improving system performance. This paper offers a new Fitness-based elephantherdingalgorithm (F-EHA) for selecting the optimal broadcast antenna by specifying many criteria such as secrecy rate and efficiency. In addition, the system provides a recommendation for which antenna to use. Finally, the suggested model's advantage over existing techniques in terms of EE (Energy Efficiency) and secrecy rate is demonstrated.

Because of the variety of shapes, locations, and image intensities, image segmentation is a more difficult endeavor in image processing. The most frequent diseases in the world are brain tumors. Therefore, brain tumor segmentation is essential in the medical field. The objective of this work is to propose image denoising and segmentation algorithms, as image segmentation is highly dependent on image denoising. The proposed image denoising algorithm is included in this article as part of the pre-processing stage. For image denoising, a novel adaptive diffusivity function based on partial differential equations is implemented. The diffusivity function's purpose is to enhance the images of brain tumors using a gradient, a Laplacian, and an adaptive threshold while also preserving image details. For image segmentation, the enhanced image is fed into an improved multi-kernel fuzzy c-means method, which then optimizes the centroid using an elephant herding optimization algorithm. Finally, it differentiates between tumor and non-tumor tissue. Images from the BRATS2020 Database were used to assess the effectiveness of the proposed approaches. When compared to conventional techniques, the proposed method performs well and proves to be an effective technique (PSNR-39.4001dBs, SSIM-99.78%, and MSE-7.4656 for image denoising;Sensitivity-98.45%, specificity-99.87%, and accuracy-99.83% for image segmentation at sigma= 20). The proposed method is developed and demonstrated in the MATLAB environment.

Supervisory control and data acquisition (SCADA) stands as a control system consisting of computers and networked data communications. At present, many industries use SCADA to monitor as well as control the processes. In recent days, numerous attacks are targeting these systems. Thus, the furtherance of high-security SCADA is much-needed one on account of its susceptibility to attacks centered on the architectural restriction. To identify these attacks, numerous classifications, optimization methods, and intrusion detecting systems (IDS) are posited. The chief drawbacks of this prevailing work are detecting accuracy, high training time, and security. For prevailing over these disadvantages, an NK-RNN classifier is proposed to recognize the intrusions in the SCADA method. Initially, the features from the datasets are organized, and the important attributes are chosen by utilizing the elephantherdingoptimization (EHO). Secondly, the data, which is optimized, are grouped and classified by applying the NK-RNN classifier. Then, the outcomes, which are classified, are assessed and utilized to outcome prediction. In normal data, Caesar Ciphering is employed for the prevention of attacks and also the modified elliptic curve cryptography is employed for enhancing the security level. From the performance assessment, it is revealed that the NK-RNN method attains superior performance than the prevailing classification method along with IDS algorithms.

Countering the issue of low optimization accuracy and poor stability of the elephantherdingoptimization (EHO) algorithm when solving multi-dimensional nonlinear complex problems, putting forward an improved elephantherdingoptimization (IEHO) algorithm. The algorithm improves the accuracy of EHO algorithmoptimization by chaosing the initial solution, adding dynamic influence factors, Levy flight operators and boundary mutation operators in the position update process. Standard functions are used for test experiments, and the results indicate that the introduction of improved strategies can effectively improve the accuracy and stability of the EHO algorithm when solving optimization problems. In view of the performance of the IEHO algorithm in function optimization, combining it with the BP neural network, proposing the IEHO-BP neural network algorithm, and using new algorithm to forecasting the building cooling and heating load. The experimental results show that compared with other group intelligence optimizationalgorithms, the output results of the cooling and heating load forecasting model based on the IEHO-BP neural network algorithm are more accurate and less oscillating.

Swarm intelligence algorithms are stochastic algorithms, i.e. they perform some random movement. This random movement imparts the algorithms with exploration capabilities and allows them to escape local optima. Exploration at the start of execution helps with thorough inspection of the search/solution space. However, as the algorithm progresses, the focus should ideally shift from exploration to exploitation. This shift would help the algorithm to enhance existing solutions and improve its convergence capabilities. Hence if the range of random movement is not kept in check, it may limit an algorithm's convergence capabilities and overall efficiency. To ensure that the convergence of an algorithm is not compromised, an improved search technique to reduce range of uniform random movement was recently proposed for bat algorithm. Uniform distribution and levy distribution are the most commonly used random distributions in swarm algorithms. In this paper, the applicability of the improved search technique over different swarm algorithms employing uniform and levy distributions, as well as Cauchy distribution has been studied. The selected algorithms are firefly algorithm, cuckoo search algorithm, moth search algorithm, whale optimizationalgorithm, earthworm optimizationalgorithm and elephant herding optimization algorithm. The resultant variants of each of these algorithms show improvement upon inclusion of the improved search technique. Hence results establish that the improved search technique has positive influence over swarm algorithms employing different random distributions.

In this paper, a multi-objective optimization method has been established on a hybrid PV, wind, fuel cell, and battery system. The optimization is based on three models including energy supply reliability, electricity efficiency, and capital cost of the hybrid system. A new model of the elephantherdingoptimization (BEHO) algorithm is utilized to solve the multi-objective optimization problem and is validated based on different algorithms and benchmark functions. The main purpose is to determine the Pareto surface including a set of possible design solutions to help the decision-makers obtaining the global optimum solution. The final results indicated that the proposed method is an applicable approach for designing of the proposed hybrid system. (C) 2020 The Authors. Published by Elsevier Ltd.
