A Secure and Cost-Effective IoT Framework for Scalable Smart Lighting and Appliance Control

2025-10-04T10:40:32+00:00

An IoT-based smart lighting and appliance control system using an Arduino Mega, relay modules, and motion sensors is designed and implemented with very Low cost. The system allows remote operation of lights, fans, and air conditioners through a web application developed with Angular (frontend) and Node.js (backend). Communication between the hardware and server is handled via the MQTT protocol. To enhance security, a selfhosted MQTT server was developed, ensuring controlled access, encrypted communication, and authentication for connected devices. Self-hosted MQTT server prevents unauthorized commands and data interception, addressing common vulnerabilities found in public MQTT brokers. Additionally, the system incorporates motion sensor-based automation, enabling lights to turn on only when movement is detected, thereby improving energy efficiency. Testing confirmed the system’s ability to deliver secure, fast, and reliable control, making it suitable for residential and commercial applications, with potential for future scalability.

Secure E-Voting using Blockchain and IoT Integration

Electronic voting has long promised speed and convenience, yet concerns over privacy, security, and voter trust remain major obstacles. This survey explores how blockchain technology can transform e-voting into a transparent, tamper-proof, and verifiable system. By leveraging the blockchain’s immutability, decentralisation, and cryptographic safeguards, votes can be secured against fraud while preserving voter anonymity. The paper reviews existing blockchain-based e-voting models, highlighting their advantages and challenges, including scalability, usability, and legal adoption. Findings suggest that blockchain has the potential to revolutionise democratic elections, but widespread implementation demands deeper research and real-world validation.
