A blockchain-driven intrusion detection model for secure communication in IoT-WSN mesh architectures G. Elumalai, J. Arun Kumar, P. Sivakumar, V. V. Teresa Peer to Peer Networking and Applications, 2026 The IoT-WSNs face the challenge of intrusion detection in wireless sensor networks due to dynamic patterns of traffic, limited resources of nodes, threat to privacy and susceptibility to routing and learning level attacks. Current intrusion detection systems (IDS) are either centralized learning which compromises on privacy and scalability or use federated learning which is not robust enough to handle model poisoning, manipulation of trust and routing level attacks. Furthermore, blockchain-based IDS systems have significant latency and overhead that restrict their functionality in resource-limited WSN. These constraints indicate a critical breach when it comes to realizing the lightweight, privacy-preserving, and trust-aware intrusion detection with a realistic implementation cost. This paper will fill this gap by proposing a secure federated blockchain-enabled IDS model of IoT-WSNs called SecuMesh-Net. The framework combines a temporal anomaly detector, based on Autoencoder and GRU, with federated learning to train models when decentralized, data privacy through the use of differential privacy, and finally, a blockchain based on PBFT to allow trust auditing and enforce routing security. The smart contracts provide trust- and energy-aware routing by isolating malicious nodes in real time and maintain the stability of the network. SecuMesh-Net is novel in its integrated approach to the time anomaly modelling, federated learning resilience, and lightweight blockchain auditing, separating consensus and operations of the IDS that require low latency. Comprehensive experiments based on real intrusion traces and traffic generated on NS-3 show that SecuMesh-Net has 97.4% detection, 2.1% false positive and 61 ms average latency, and per-event energy use of 2.4 mJ. These findings affirm the applicability, effectiveness, and suitability of the framework to practical uses of the IoT-WSN.
Thermal vision for lady finger quality assessment: A three-stage convolutional neural network approach Santi Kumari Behera, P Bharat Siva Varma, V V Teresa, Kalyan Das, Prabira Kumar Sethy, Aziz Nanthaamornphong International Journal of Food Science and Technology, 2025 Lady finger is an important commercial crop that is nutritionally rich and has extensive culinary applications. The present research paper introduced a new technique for the nondestructive postharvest classification of okra pods (Clemson Spineless type) into suitably matured or overmatured okra pods using thermal images and the three-stage convolutional neural network (CNN) technique based on EfficientNetB7. For the thermal photography of lady finger pods, an FLIR E75 Thermal imaging unit was used, and the distance of both the cameras and lady finger was kept at a minimum of more than 0.5 m. The proposed CNN-based technique results were reported in the form of accuracy, sensitivity, specificity, precision, and F1-score, which were 0.9700, 0.9800, 0.9600, 0.9608, and 0.9703, respectively. In other words, the FPR for our classification model was reported to be 0.0400. The results of MCC and kappa statistics were also reported to be 0.9402 and 0.9400, which indicates that a strong agreement was found between the predicted and actual classifications of overmature and suitably matured okra pods. The experiment shows that the suggested approach could be utilised for the nondestructive classification of lady finger pods into suitably matured or overmatured ones.
AREA-DELAY-POWER-EFFICIENT GDI ARCHITECTURE SELECT ADDER TO CARRY R. Saranya, B. Paulchamy, K. Kalpana, V.V. Teresa, P. Logamurthy E3s Web of Conferences, 2025 The signal processing system is extremely popular in this day and age. All of the primary circuits in the digital signal processing system are built around the adder, which is the fundamental building block. Today’s needs for lowering the delay, space, and power consumption of adder circuits boost the overall efficiency of the system, propelling it to the next stage of technological development. Despite the fact that the Carry Select Adder (CSLA) takes up more space, it is being utilised in place of the ripple carry adder in order to reduce propagation delays. In other models, a Carry Select Adder based on a Binary to Excess-I Converter (BEC) was utilised, which required fewer logic resources than a standard CSLA and was hence more energy efficient. The fact that these CSLAs reject one sum after the calculation, however, means that they are not more efficient. As a result, the delay was not significantly decreased. It is necessary to apply the reduced logic CSLA in order to overcome this challenge. However, by employing the Gate Diffusion Input (GDI) Technique, it is possible to achieve a lower delay than the previously suggested reduced logic CSLA. The suggested technique consumes less power and has a shorter propagation latency than existing techniques. In addition, the number of transistors necessary for the circuit was reduced by implementing this GDI-based CSLA. It is possible to create an efficient adder using this technique, as seen above.
A Compact Proximity-Coupled Antenna Array for Multi-Band 5G and 6G Wireless Communication Systems Sreejith. A.R, K.K. Anilkumar, Bose. V.V, V.V. Teresa Proceedings 2025 2nd International Conference on Electronic Circuits and Signaling Technologies Icecst 2025, 2025 The rapid evolution of wireless communication technologies demands compact, high-performance antenna systems that can support multi-band operation across both sub-6 GHz and millimeter-wave (mmWave) spectra. In this work, we present a compact proximity-coupled antenna array designed specifically for multi-band 5G and 6G wireless communication systems. The proposed design employs a dual-layer substrate structure with proximity coupling between the feedline and radiating patch, enabling enhanced impedance bandwidth and radiation efficiency while maintaining a low-profile configuration. The antenna is optimized to operate at 3.5 GHz (n78), <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$28 \text{GHz}(5 \mathrm{G} \text{mmWave})$</tex>, and 140 GHz (targeted 6G band), achieving a measured impedance bandwidth of 13.2%, 18.5%, and 11.6% respectively at each band. The antenna gain reaches up to 8.7 dBi at 28 GHz and 10.4 dBi at 140 GHz, making it highly suitable for high-data-rate and long-range communication. The array configuration exhibits excellent port isolation (<tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$>30\ \text{dB}$</tex>) and a low envelope correlation coefficient (ECC <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$<0.005$</tex>), ensuring its viability for MIMO applications. Moreover, the overall antenna footprint is compact (<tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$15 \text{mm} \times 12$</tex> mm per element), facilitating integration into mobile and IoT platforms. The proposed antenna demonstrates stable radiation patterns, with cross-polarization levels below −20 dB, and maintains over 85% radiation efficiency across all targeted bands. These results validate the potential of proximity-coupled techniques in enabling compact, wideband, and high-gain antenna arrays for next-generation wireless systems, particularly for 5G/6G dual-mode devices and intelligent communication environments.
EdgeMeshNet: RSSI- Based Vehicular Mesh Network for Accident Alerts in Mountainous Regions Vigneshkumar R, Sudheshna P, Sudharshana D, Sreenithi V, Teresa V V IC Decon 2025 2025 International Conference on Data Energy and Communication Network Proceedings, 2025 A top way to reduce fatalities and injuries is providing accident event reporting in a timely manner. This can often be an issue in rural and mountainous area where the cell phone signal is limited, low or non-existent. This can cause delays in emergency support and assistance for a reporting party if systems of communication fail. The rugged terrain can limit or blind radio signals, and the available cell towers may not provide coverage, and texting a report may not be viable. Also be aware that the decision process of an accident report for some individuals is influenced by their fear of repercussions. Cellular communication between cars is not solacious much of use and often just utilizing basic communication such as verbal or text message. To alleviate some of these areas of concern, this study calls to introduces EdgeMeshNet, an intelligent car communication system that allow vehicles to communicate directly to the road signs and other vehicles via a mesh network. The EdgeMeshNet mesh network is established ad hoc, and it establishes a self-healing type of connectivity if faulty connections exist. Specific to EdgeMeshNet, it will not use cellular networks to establish connectivity. The vehicular communication scheme will use a peer-to-peer type arrangement wherein vehicles can communicate and receive information from their own sensors (vehicles) as well their peers (other vehicles). The Edge nodes use the signal strength parameters to find the ideal path for message travelling “routes”, so that even in continuous change and constant travel situation there are advantages to communicating. EdgeMeshNet is developed with the ESP8266 low-power wireless modules and simulated on the Arduino IDE. It consists of three main features: (1) fast accident alerts, (2) high message delivery rate regardless of few cars or many cars on the road, and (3) the system works well with very little energy. The revised design does not need drastic changes to the roadways, making it affordable and practical. EdgeMeshNet provides real-time accident notifications where there is little or no cell coverage to facilitate quicker and better coordinated emergency responders, which will save lives on high-speed mountain roads with frequent automobile accidents.
An Integrated IoT Architecture for Real-Time Detection and Remote Tracking of Dementia Symptoms D. Shamia, V.V. Teresa, Harish Ragavendra M, Kaviarasu P, Akash R, Simiyon A Proceedings of International Conference on Modern Sustainable Systems Cmss 2025, 2025 Dementia is a degenerative neurological condition that significantly affects both mental and physical abilities. Detecting the condition early and continuously tracking its progression are vital for improving patient outcomes and reducing the strain on caregivers. This paper introduces an IoT-enabled monitoring solution specifically designed for individuals with dementia. The proposed system combines wearable biomedical sensors, real-time data acquisition, and cloud-based analytics to monitor key physiological and cognitive indicators. At its core, the system utilizes an ESP32 microcontroller to collect real-time information from sensors such as ECG, heart rate, pulse oximeter, and body temperature sensors enabling the identification of dementia-related symptoms. When irregularities are identified, the system activates a buzzer and sends immediate alerts via the cloud to caregivers, medical professionals, and family members. The cloud platform facilitates not only remote observation but also pattern detection and long-term data trend analysis. In contrast to conventional methods, this approach offers better accuracy, lower costs, and improved accessibility, while also addressing issues like inconsistent data and low patient compliance. Experimental testing confirms the system’s effectiveness in identifying abnormal physiological states, suggesting its potential in early diagnosis and long-term dementia care. Future enhancements will focus on incorporating machine learning for predictive analysis and developing strategies to improve user interaction and adoption.
Integrating Sentiment Analysis with Learning Analytics for Improved Student B. Paulchamy, Vairaprakash Selvaraj, N.M. Indumathi, K. Ananthi, V.V. Teresa International Journal of Computational and Experimental Science and Engineering, 2024 The integration of sentiment analysis with learning analytics offers a novel approach to improving student outcomes by providing deeper insights into the emotional and cognitive states of learners. This research explores the use of sentiment analysis on student interactions, such as online discussions, assignments, and feedback, to assess the emotional tone of student engagement. By combining these sentiment insights with traditional learning analytics, which track academic progress and behavior patterns, this study aims to create a comprehensive model that enhances the identification of students at risk, tailor educational interventions, and fosters personalized learning experiences. The proposed approach not only improves the monitoring of student well-being and engagement but also supports the development of adaptive learning systems that respond to students’ emotional states. Results show that sentiment analysis integrated with learning analytics can provide real-time feedback for educators, enhancing student support and improving overall academic performance
An Energy-Efficient improved Grey Wolf Optimization Algorithm-Based Cluster Head and Shamir Secrets Sharing-Based WSNs with Secure Data Transfer Yuvaraja M, Sureshkumar S, Joseph James S, Teresa V V Salud Ciencia Y Tecnologia Serie De Conferencias, 2024 Introduction: Due to its self-configurability, ease of maintenance, and scalability capabilities, WSNs (Wireless Sensor Networks) have intrigued plenty of interest in a variety of fields. To move data within the network, WSNs are set up with more nodes. The security of SNs (sensing nodes), which are vulnerable to malevolent attackers since they are network nodes, is a crucial element of an IoT (Internet of Things)-based WSN. This study's primary objective is to provide safe routing and mutual authentication with IoT-based WSNs. Methods: The basic GWO algorithm's imbalances between explorations and mining, lack of population heterogeneity, and early convergences are all issues that this paper addresses by selecting energy-efficient CHs (cluster Heads) using EECIGWO algorithm, an upgraded version of the GWO, is used. Mean distances within clusters, well-spaced residual energies, and equilibrium of CHs are all factors that influence the choices of CHs. The average intra-cluster distances, sink distances, residual energies, and CHs balances are some of the criteria used to choose CHs. Results and Discussion: The proposed EECHIGWO-based clustering protocol's average throughput, dead node counts, energy consumption, and operation round counts have all been evaluated. Additionally, mutual authentication between the nodes is provided through SSS (Shamir Secret Sharing) mechanism. PDR (Packet Delivery Ratio) analysis is used to assess how well the EECHIGWO-IOT-WSNs are performing. Conclusion: The suggested proposed approach is assessed against existing methods like HHH-SS (Hybrid Harris Hawk and Salp Swarm), ESR (Energy-efficient and Secure Routing) protocol, and LWTS (Light Weight Trust Sensing) approaches in terms of AEED (Average End-to-End Delay), network overheads, and PLR (Packet Loss Ratio).
