Compact FR-4-Based Wearable LoRa Antenna with Enhanced SAR Performance Kowsalya P, A.Yogeshwaran, Rajeswari.P 2025 IEEE 3rd Global Conference on Wireless Computing and Networking Gcwcn 2025, 2025 The paper provides the design and analysis of a miniature low-cost wearable antenna optimized at LoRa communication system within the sub-GHz frequency range. The suggested design is a meandered monopole antenna mounted on a FR-4 epoxy substrate (εr = 4.4, tanδ = 0.02 ) with a total area of 50*45 mm<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup>, which is very small in terms of size when compared to the standard designs. Wide-band optimum parametric optimization was done to improve impedance matching and radiation performance at 890–910 MHz spectrum. An in-depth substrate analysis was drawn between FR-4 and Rogers 5880 and Rogers 6006 and they affirmed that FR-4 is the most cost-effective and efficient in wearable applications. The antenna has been shown to have a return loss of less than 20dB, a gain of 1.55-3.6dBi as well as a radiation efficiency in excess of 84%. Specific Absorption Rate (SAR) measurements with IEEE C95.1 human phantom models produced 1.12 W/kg (1 g) and 1.78 W/kg (10 g) both minimum values in the FCC and ICNIRP safety limits. Simulations were found to agree with the experimental validation using VNA and anechoic chamber measurements. The findings prove the proposed FR-4-based antenna as a stable, affordable, and bio-safe implementation to next-generation wearable system IoT and LoRa-based communications systems.
Identifying False Injection Packet Transmission using SVM and Secure OLSR in Wireless Sensor Networks R. Kalaimathi, A. Yogeshwaran, P. Rajeswari 4th IEEE International Conference on Distributed Computing and Electrical Circuits and Electronics Icdcece 2025, 2025 Wireless Sensor Networks (WSNs) are systems of wirelessly communicating, geographically scattered sensor nodes that collect, process, and transmit data. Examples of applications for these networks are smart cities, industrial automation, healthcare, military, and environmental monitoring. Several research studies have been conducted on securing WSNs against false injection attacks, anomaly detection, and optimizing routing protocols. If a legitimate packet is accidentally discarded, vital information can be lost, and applications that rely on data accuracy can be compromised. To resolve the issue, this paper proposes an integrated security framework that combines Support Vector Machines (SVMs) for anomaly detection and Optimal LinkState Routing (OLSR) to achieve secure and efficient routing to avoid false injection in the WSN environment. Before detecting the anomaly, a Fuzzy clustering method is used to create the cluster and also select the appropriate cluster. After selecting the suitable cluster, the SVM model is trained to detect spuriously injected packets and anomaly nodes. Simultaneously, OLSR ensures secure and energy-efficient routing through cryptographic authentication and trusted path selection. The proposed model outcomes demonstrate that the suggested method accomplishes a Packet Delivery Rate (PDR) of 92% and an accuracy of 95% in detecting false injection attempts. In addition, energy consumption is reduced by 14% compared to traditional routing methods, significantly extending the network lifetime. The results show that integrating SVM and OLSR can effectively suppress false packet injection and improve WSN performance.
Enhanced Energy Efficient Routing Protocol Based Adaptive Multipath Routing Protocol for Improving Wireless Network S Vanmathi., P. Rajeswari, A. Yogeshwaran 3rd IEEE International Conference on Data Science and Network Security Icdsns 2025, 2025 Over the past decade, numerous routing algorithms have been proposed for ad hoc wireless networks, though many require high bandwidth for complete routing processes. To address this, we focus on real-time dataset transmission under low-bandwidth conditions and introduce secure message delivery systems. However, existing methods often suffer from high packet delay and issues with inferring the routing path. To overcome these challenges, we propose the Energy-Efficient Opportunistic Routing Protocol (EEORP), which enhances accuracy and reliability while conserving energy. We also introduce Neighbor-Aware Random Sampling (NARS) to estimate performance and resource availability using probability <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$Pi$</tex> at each node. Additionally, the Adaptive Multipath Routing Protocol (AMPRP) evaluates node performance within neighbour clusters and calculates energy transmission ratios. The results demonstrate improved throughput, higher detection rates, reduced energy consumption and delay, achieving an overall performance of 95%. These proposed methods select optimal forwarding nodes and measure energy efficiency using both adjustable and non-adjustable parameters.
Simulation Design of Low-Profile Equilateral Triangle Microstrip Patch Antenna Yogeshwaran A, Divyabharathi S, Harisha K, Jeevitha S, Madhurambika S 3rd International Conference on Data Science and Information System Icdsis 2025, 2025 Background: An equilateral triangular microstrip patch antenna (ETMPA) suitable for 5G application technologies is being developed at a frequency of 28 GHz. Methods used: During the design phase, inset feed strategies are considered, antenna parameters are calculated, and their performance is evaluated using computer simulation technology (CST) and the High-Frequency Simulator system (HFSS). To achieve these objectives, several substrate materials of different heights and conductor patch material types are used, and their effects on the radiation performance of the antenna are investigated. Taconic-TLX-9 dielectric substrates made of copper and measuring h-0.2 mm in height bonding material are often used to create a dependable minimal low-profile (ETMPA) (4.59 mm3) with dependable radiation performance, according to simulation results. Results: Both methods have the S11, VSWR, efficiency, mobility, Gain, and bandwidth based on the standards above. Conclusion: Lastly, the suggested antenna design is one of the prerequisites for 5G technology and is smaller than most previous attempts.

A, Suriya Prakash T, Nandha Kumar R, Ragavendra A, Tamilarasu P 4th International Conference on Automation Computing and Renewable Systems Icacrs 2025 Proceedings, 2025 Agriculture is the backbone of the world economy, and improving the productivity and sustainability requires a consistent technological transformation. The smart system of the monitoring of agricultural parameters based on the Internet of Things (IoT) is the automatization of the acquisition of and monitoring of vital parameters of agriculture in real time. The ESP32 controller has sensors that constantly monitor the moisture levels in soil, temperatures, humidity, and pH levels of soil. Data obtained is sent to a cloud platform through Wi-Fi allowing farmers to view real-time analytics using a mobile application like Adafruit to make effective decisions. It also involves an automated irrigation mechanism that maximizes the use of water, saves on labour and increases crop production. The proposed system will embrace data analytics, cloud computing, and renewable energy in real-time so as to enhance the use of resources and sustainability unlike the earlier models that could not achieve this with lack of cloud computing and real-time data analytics. Experimental study indicates that the given framework has the possibility to boost productivity and minimize waste in small-scale farms. Therefore, the system suggested is an intelligent, stable and sustainable solution to the contemporary agricultural management.
