Energy Efficient Clustering and Sink Mobility Protocol Using Hybrid Golden Jackal and Improved Whale Optimization Algorithm for Improving Network Longevity in WSNs S. B. Lenin, R. Sugumar, J. S. Adeline Johnsana, N. Tamilarasan, R. Nathiya China Communications, 2025 Reliable Cluster Head (CH) selection-based routing protocols are necessary for increasing the packet transmission efficiency with optimal path discovery that never introduces degradation over the transmission reliability. In this paper, Hybrid Golden Jackal, and Improved Whale Optimization Algorithm (HGJIWOA) is proposed as an effective and optimal routing protocol that guarantees efficient routing of data packets in the established between the CHs and the movable sink. This HGJIWOA included the phases of Dynamic Lens-Imaging Learning Strategy and Novel Update Rules for determining the reliable route essential for data packets broadcasting attained through fitness measure estimation-based CH selection. The process of CH selection achieved using Golden Jackal Optimization Algorithm (GJOA) completely depends on the factors of maintainability, consistency, trust, delay, and energy. The adopted GJOA algorithm play a dominant role in determining the optimal path of routing depending on the parameter of reduced delay and minimal distance. It further utilized Improved Whale Optimisation Algorithm (IWOA) for forwarding the data from chosen CHs to the BS via optimized route depending on the parameters of energy and distance. It also included a reliable route maintenance process that aids in deciding the selected route through which data need to be transmitted or re-routed. The simulation outcomes of the proposed HGJIWOA mechanism with different sensor nodes confirmed an improved mean throughput of 18.21%, sustained residual energy of 19.64% with minimized end-to-end delay of 21.82%, better than the competitive CH selection approaches.
A Smart Urine Analysis Device for Diabetic Patients Mohanram S, Lenin SB, Kowsalya V, Sarangi K, Yuvashree G, Meena A 2025 International Conference on Emerging Technologies in Engineering Applications Icetea 2025 Proceedings, 2025 Numerous cutting-edge technologies with accessible processing techniques are required in the social health care sectors. This might reduce costs and boost accessibility to address various issues with real-time services. The use of a urine dipstick is a kind of the healthcare services that are employed in real-time. Urinalysis, or the examination of a urine sample, is a potent method for obtaining crucial information for diagnostic reasons in medicine. A urine test strip is frequently employed in these kind of evaluation. In this work, a real-time implantation for image-processing-based urine test strip analysis was created. The outcome is determined by the strip's colour. However, it could result in observed variations in the colour reading. In this study, digital image processing methods such segmentation, thresholding, smoothing, and recognition were also applied. For classification, a common back propagation technique is computed here. The statistical interpretation, including the positive (PPV) and negative (NPV) predictive values, was evaluated using cross-validation findings. The output demonstrates that the suggested technique has a 96% accuracy in classifying the colours on a urine dipstick.
Design and Analysis of 8 Element MIMO Yagi-Uda Array Antenna For 5G Mobile Terminal Application S Mohanram, Sb Lenin, C Agilan, N Raguram, K Yuvaraj, C Jagatheeswara Moorthy, N Tamilarasan 2025 IEEE International Conference on Intelligent Signal Processing and Effective Communication Technologies Inspect 2025, 2025 This paper introduces an innovative design for an 8-element Quasi Yagi-Uda array antenna tailored for next-generation 5G mobile terminal applications. The proposed array features a compact structure with dimensions of $164 \times 249 \times 1.15 \mathrm{~mm}^{3}$. The design originates from a single-element Yagi antenna, achieving a peak gain of $\mathbf{4. 7 6 ~ d B i}$ at $\mathbf{3. 6 ~ G H z}$. By arranging eight single-element antennas in a $4 \times 2$ configuration, the array attains an enhanced peak gain of 8.63 dBi at the same frequency. The antenna array demonstrates superior performance in terms of gain, directivity, and impedance matching. Simulated results confirm that this novel design is a promising candidate for advanced $\mathbf{5 G}$ mobile communication systems, offering excellent efficiency and reliability to meet the demands of future wireless technologies.
Stochastic Ranking Improved Teaching-Learning and Adaptive Grasshopper Optimization Algorithm-Based Clustering Scheme for Augmenting Network Lifetime in WSNs N. Tamilarasan, S. B. Lenin, P. Mukunthan, N. C. Sendhilkumar China Communications, 2024 In Wireless Sensor Networks (WSNs), Clustering process is widely utilized for increasing the lifespan with sustained energy stability during data transmission. Several clustering protocols were devised for extending network lifetime, but most of them failed in handling the problem of fixed clustering, static rounds, and inadequate Cluster Head (CH) selection criteria which consumes more energy. In this paper, Stochastic Ranking Improved Teaching-Learning and Adaptive Grasshopper Optimization Algorithm (SRITL-AGOA)-based Clustering Scheme for energy stabilization and extending network lifespan. This SRITL-AGOA selected CH depending on the weightage of factors such as node mobility degree, neighbour's density distance to sink, single-hop or multihop communication and Residual Energy (RE) that directly influences the energy consumption of sensor nodes. In specific, Grasshopper Optimization Algorithm (GOA) is improved through tangent-based nonlinear strategy for enhancing the ability of global optimization. On the other hand, stochastic ranking and violation constraint handling strategies are embedded into Teaching-Learning-based Optimization Algorithm (TLOA) for improving its exploitation tendencies. Then, SR and VCH improved TLOA is embedded into the exploitation phase of AGOA for selecting better CH by maintaining better balance amid exploration and exploitation. Simulation results confirmed that the proposed SRITL-AGOA improved throughput by 21.86%, network stability by 18.94%, load balancing by 16.14% with minimized energy depletion by 19.21%, compared to the competitive CH selection approaches.
Wireless Coal Mine Monitoring System based on ESP-NOW Protocol for Real-Time Data Acquisition and Analysis S. B. Lenin, R. Priyadharshni, S. Mohanram, S. Ashok Kumar Journal of Engineering Science and Technology Review, 2024 Coal Mine monitoring is a critical task to ensure the safety of Miners and efficient mining operations.Traditional methods of monitoring rely on wired sensors, which are expensive to install and maintain.Wireless technologies offer a cost-effective and flexible solution to this problem.In this context, the use of the ESP-NOW protocol is proposed as a means of transmitting data from sensors in a Coal Mine to a central monitoring system where the data is processed and analysed in real time.ESP-NOW is a low-power wireless communication protocol that can be implemented on Node MCU.The proposed system can collect data from various sensors, including gas sensors, Temperature sensors, Particulate Matter sensors, and Humidity sensors, and send the data wirelessly to the nodes that are fixed at different locations on a tunnel surface that is connected to the central monitoring station.The system can detect potential safety hazards and provide early warning alerts to Mine operators as well as it is used in tracking the workers.The results demonstrate the effectiveness of ESP-NOW in Coal Mine monitoring where real-time data transmission is critical.

Aswin Proceedings of the International Conference on Circuit Power and Computing Technologies Iccpct 2023, 2023 Facial recognition technology has been widely used in various industries for identification and tracking purposes. However, the integration of facial recognition with Electrostatic Discharging testers is constrained by data security and privacy issues. To address these concerns, this investigation proposes a federated learning model approach for integrating facial recognition technology with ESD testers. The Integration of Facial recognition with ESD tester using federated learning model with Pre-FedAvg Algorithm preserves data privacy and security by using a distributed learning approach which maintains high accuracy and efficiency of the ESD testing systems. This research evaluates performance of the proposed approach metrics like Accuracy, Precision-recall, and F1 score. Results show that this approach outperforms conventional method while preserving data from various vulnerabilities. The electronic manufacturing industries, quality control departments, and safety monitoring sections are among the key areas of this strategy. It has the potential to revolutionize the way ESD testing is performed and enhances the safety and reliability of electronic devices and new dimensionality of features in factory processes like calculating over time of workers and making ESD proof.
