Mobile Ad-hoc Network (MANET) becomes the facilitating and emerging trends for data transmission. Due to the nodes are freely connected with each other, the challenging is to provide the secure transmission. To attain this objective, the Adaptive Fractional lion TOpology-HIding multipath routing protocol (AFL-TOHIP) is proposed. The TOHIP protocol constitutes route request phase, route reply phase and route probe phase, to acquire the multiple numbers of disjoint paths in MANET. Consequently, the proposed algorithm is developed to select the optimal routing path. Here, the fractional calculus is utilized to integrate with the lion optimization algorithm. Then, the fractional lion algorithm is incorporated into the TOHIP protocol, named AFL-TOHIP. In addition to improve the solution searching, the fractional lion algorithm is mathematically integrated with the TOHIP protocol. In the proposed algorithm, the fractional derivative is adapted according to the generation of the solution. Finally, the optimal routing path is obtained, used to transmit the packets from source to destination node. The extensive experimental results are evaluated using MATLAB implementation. Then, the performance is analysed compared to existing algorithms. Thus, the novel AFL-TOHIP optimization algorithm achieves 0.603 throughputs and 0.572 less delay, which enhances the transmission efficiency and robustness.

A multilevel inverter (MLI) is a power electronic device that includes the capability to offer the preferred voltage level (alternating) in the output. Accordingly, selective harmonic elimination (SHE) or pulse width modulation (PWM) methodologies were deployed widely. However, these techniques are not appropriate in a certain situation which involves a huge number of switching angles if an excellent primary guess is not obtainable. Hence, this paper intends to determine the optimum switching angles of a cascaded H-bridge multilevel inverter (CH-MLI) using a hybrid lion optimization algorithm (LOA) and binary cat swarm algorithm (BCSO). The objective of optimizing the switching angle is to generate the needed fundamental voltage and minimize the harmonic content. This is done by resolving the transcendental equations characterizing the harmonic content. The switching angles, i.e., alpha(1), alpha(2).... alpha(m), should be tuned in such a way that it satisfies the condition 0 < alpha(1), alpha(2) ....< alpha(m) < pi/2 Here, the optimal tuning of switching angles is done by the proposed binary cat cubpool-based lion algorithm (BCC-LA). In addition, the analysis is done for the proposed method over the state-of-the-art models in terms of total harmonic distortion (THD), and the impact of varying loads is also examined for the proposed and traditional models, and thus, the superior performance of the proposed model is validated.

CKD is a medical condition that affects people all around the world and is a major health concern. It increases the risk of developing cardiovascular and cerebrovascular diseases, which can lead to serious illness and even death. Ultrasound imaging is typically the initial and most widely used diagnostic technique for individuals at risk for CKD. The existing methods are restricted by features with high dimensions, computational hurdles, and extended processing times. To address these issues, this article proposes the development of an enhanced deep-learning model with an optimum selection of features for the accurate diagnosis of CKD. The proposed technique begins with pre-processing, involving image filtering and contrast enhancement. Then, presented an improved Otsu's algorithm for segmenting kidney masses, followed by a stage of feature extraction. A hybrid lion optimization algorithm (LOA) and Moth flame optimization (MFO) is a novel contributions to improve the convergence rate of the MFO algorithm. The hybrid FS algorithms select the optimal subset of features for disease classification. Finally, a novel Long-Term Recurrent Convolutional Network (LRCN) is introduced for detecting kidney impairment. The models are developed and validated utilizing a database of ultrasonography (US) images including four classes of Chronic kidney images: stone, cyst, tumor, and normal. The efficiency of the framework is assessed based on its of accuracy, precision, recall, F1-score, and specificity of 98.7%, 96.6%, 96.4%, 97.9%, and 96.2% respectively. In addition, testing results show that the framework obtains the best overall performance when compared to existing methods for the classification of ultrasound images.

Designing an ANN is a complex task as its performance is highly dependent on the network architecture as well as the training algorithm used to select proper synaptic weights and biases. Choosing an optimal design leads to greater accuracy when the ANN is used for classification. In this paper, we propose an approach multilayer perceptron-lion optimization algorithm (MLP-LOA) that uses lion optimization algorithm to find an optimum multilayer perceptron (MLP) architecture for a given classification problem. MLP-LOA uses back-propagation (BP) for training during the optimization process. MLP-LOA also optimizes learning rate and momentum as they have a significant role while training MLP using BP. LOA is a population-based metaheuristic algorithm inspired by the lifestyle of lions and their cooperative behavior. LOA, unlike other metaheuristics, uses different strategies to search for optimal solution, performs strong local search and helps to escape from worst solutions. A new fitness function is proposed to evaluate MLP based on its generalization ability as well as the network's complexity. This is done to avoid dense architectures as they increase chances of overfitting. The proposed approach is tested on different classification problems selected from University of California Irvine repository and compared with the existing state-of-the-art techniques in terms of accuracy achieved during testing phase. Experimental results show that MLP-LOA performs better as compared to the existing state-of-the-art techniques.

The main aim of this paper is to introduce a framework for the design and modelling of a photovoltaic (PV)-wind hybrid system and its control strategies. The purpose of these control techniques is to regulate continuous changes in the operational requirements of the hybrid system;currently, in power system networks, the distribution of energy plays a major role in maintaining power reliability in distribution systems. In this study, the proposed hybrid system was incorporated with a combined PV and wind energy system. Maximum power point tracking (MPPT) methods have been proposed to achieve maximum efficiency from the designed system. In addition, this study focused on improving the stability of the hybrid system. To improve the power quality and transient stability of the proposed system, we introduce a novel control strategy called the distributed power flow controller (DPFC) implementation with an optimization technique called the lion optimization algorithm(LOA)technique. This LOA control technique was developed for the first time in the application of a DPFC controller in a grid-connected system. The control technique was developed using signals from the system parameters, that is, voltage and current. To tune these parameters, this study used fuzzy logic and lion optimization techniques. The proposed system with controllers was tested in MATLAB/Simulink and the results were compared.

VLSI floorplan optimization problem aim to minimize the following measures such as, area, wirelength and dead space (unused space) between modules. This paper proposed a method for solving floorplan optimization problem using Genetic algorithm which is named as 'lion optimization algorithm' (LOA). LOA is developed for non-slicing floorplans having soft modules with fixed-outline constraint. Although a number of GAs are developed for solving VLSI floorplan optimization problems, they are using weighted sum approach with single objective optimization and crossover between two B*tree structure is not yet attempted. This paper explains, power of B*tree crossover operator for multiobjective floorplanning problem. This operator introduces additional perturbations in initial B*tree structure to create two new different B*tree structures compared with classical GA approach. Simulation results on Microelectronics Center of North Carolina and Gigascale Systems Research Center benchmarks indicate that LOA floorplanner achieves significant savings in wirelength and area minimization also produces better results for dead space minimization compared to previous floorplanners.

The application of remote sensory images in crop monitoring has been increasing in the recent years due to its high classification accuracy. In this paper, a novel parallel classification methodology is proposed using a new clustering and classification concept. A novel neural network model with the Bs-lion training algorithm is developed by integrating the Bayesian regularization training with the lion algorithm. Here, two levels of parallel processing are performed, namely parallel WLI-Fuzzy clustering and parallel BS-lion neural network classification. The experimentation of the proposed parallel methodology is carried out using satellite images obtained from the Indian remote sensing satellite IRS-P6. The performance of the proposed system is compared with the existing techniques using validation measures accuracy, sensitivity and specificity. The experimentations resulted in promising results with an accuracy of 0.8994, sensitivity of 0.8682 and specificity of 0.8739, which favour the performance of the proposed parallel architecture in the classification.

An intelligent segmentation and identification of edemas diseases constitutes a most important crucial ophthalmological issues since they provide important information for the diagnosis process in accordance to the disease severity. But diagnosing the different edema diseases using the OCT-images are considered to be daunting challenge among the researchers. The implementation of computational intelligence techniques such as machine learning, deep learning, bio inspired algorithms and image processing techniques may help the doctors for some extent in improving the automatic extraction and diagnosis process consequently improving patients' life quality. But, these are liable to more errors and less performance, which requires further improvisation in designing the intelligent systems for an effective classification of edema diseases. In this context, this paper proposes the hybrid intelligent framework for the identification, segmentation and classification of three types of edemas such as using the retinal optical coherence tomography (OCT) Images. In this process, Single Feed Forward Training networks (SLFTN) are integrated with Convolutional Layers whose hyperparameters are tuned by using lion optimization algorithm. An intensive experimentation is carried out using the Kaggle Retinal OCT Image datasets-2020 with Tensor flow and the proposed framework is trained with the different set of 84,494 images in which performance metrics such as accuracy, sensitivity, specificity, recall and f1score are calculated. Results shows the proposed system has provided satisfactory performance, reaching the average highest accuracy of 99.9% in identifying and classifying the respectively.

Text mining has become a major research topic in which text classification is the important task for finding the relevant information from the new document. Accordingly, this paper presents a semantic word processing technique for text categorization that utilizes semantic keywords, instead of using independent features of the keywords in the documents. Hence, the dimensionality of the search space can be reduced. Here, the Back Propagation lion algorithm (BP lion algorithm) is also proposed to overcome the problem in updating the neuron weight. The proposed text classification methodology is experimented over two data sets, namely, 20 Newsgroup and Reuter. The performance of the proposed BPlion is analysed, in terms of sensitivity, specificity, and accuracy, and compared with the performance of the existing works. The result shows that the proposed BPlion algorithm and semantic processing methodology classifies the documents with less training time and more classification accuracy of 90.9%.
