AIOT based Smart Education System: A Dual Layer Authentication and Context-Aware Tutoring Framework for Learning Environments

TL;DR

The paper presents an AIoT-based smart education framework that merges RFID+WiFi dual-layer attendance, an AI tutoring assistant, automated adaptive quizzes, and IoT-driven environmental control (EcoSmart Campus) into a cohesive platform. Using modular development and simulation (Wokwi, Streamlit, CLI tools), it demonstrates end-to-end integration, secure attendance, context-aware tutoring trained on instructor materials, and adaptive assessment generation, along with IoT-enabled classroom environment optimization. Key contributions include a unified architecture for secure access, real-time student support, scalable assessment, and automated climate/resource management, all evaluated in simulation to show feasibility and scalability potential. The work highlights practical implications for inclusivity, engagement, operational efficiency, and future research directions, including large-scale pilots, cloud integration, privacy-preserving AI, and multi-modal sensing.

Abstract

The AIoT-Based Smart Education System integrates Artificial Intelligence and IoT to address persistent challenges in contemporary classrooms: attendance fraud, lack of personalization, student disengagement, and inefficient resource use. The unified platform combines four core modules: (1) a dual-factor authentication system leveraging RFID-based ID scans and WiFi verification for secure, fraud-resistant attendance; (2) an AI-powered assistant that provides real-time, context-aware support and dynamic quiz generation based on instructor-supplied materials; (3) automated test generators to streamline adaptive assessment and reduce administrative overhead; and (4) the EcoSmart Campus module, which autonomously regulates classroom lighting, air quality, and temperature using IoT sensors and actuators. Simulated evaluations demonstrate the system's effectiveness in delivering robust real-time monitoring, fostering inclusive engagement, preventing fraudulent practices, and supporting operational scalability. Collectively, the AIoT-Based Smart Education System offers a secure, adaptive, and efficient learning environment, providing a scalable blueprint for future educational innovation and improved student outcomes through the synergistic application of artificial intelligence and IoT technologies.
