An Intelligent IoT-Based Automated Multimedia Dissemination Framework for Smart Campus Environments

Abstract

Modern educational institutions require instantaneous communication channels to bridge the gap between administrative updates and student awareness. Traditional notice boards and static digital displays lack responsiveness, requiring manual intervention and physical presence to update content, which leads to information latency. Conventional systems rely on USB-based manual updates or proprietary expensive software that offers limited file format support and no real-time synchronization. These methods are labour-intensive, prone to hardware wear, and fail to provide immediate updates during emergencies or sudden schedule changes. Hence, there is a critical need for a platformindependent, low-cost, and automated system that allows remote management with instant edge-node synchronization. Therefore, thisresearch proposes a lightweight, Flask-based web architecture designed for Intelligent IoT-based Automated Multimedia Dissemination (IIAMD). The system utilizes a pollingbased manifest synchronization protocol, allowing an administrative node to push high-definition multimedia content (images and videos) to distributed display nodes via a centralized websocket/RESTful interface. The proposed framework ensures 100% information consistency across the campus network. Experimental results demonstrate a significant reduction in update latency (under 15 seconds) and zero manual downtime, providing a scalable, cost-effective alternative to commercial signage solutions while enhancing the technological infrastructure of the "Smart Campus."
