A Review of IoT-Enabled Indoor Positioning, Integrating MERN Stack and RFID

In recent years, the usefulness of indoor positioning systems (IPS) to give positioning and routing services in extensive indoor spaces, which are mistaken use of traditional GPS-based management systems, has increased. On college campuses, finding faculty members, administrative personnel, or looking for specific departments becomes a daunting task that leads to delay — especially when students are in the middle of an exam or approaching the deadline for an assignment. IoT (Internet of Things) applications, such as RFId Radio-Frequency Identification integrated with a web application based on the MERN stack (MongoDB, Express. js, React. js, Node. bg) and  geolocation for seamless real-time indoor positioning system. The Creative Project Proposal is to create a web interactive page, and have people’s or students find their way to the faculty members in the college building using the web navigation through their handheld smart devices. We have different data points (locations) that faculty members register on the system, allowing for real-time location sharing that takes place through the web application. The system provides users with this dynamic and interactive 2D building layout to transition between floor levels with high visual smoothness and intuitiveness. This paper will elaborate on the core technological building blocks that come into play—such as real-time geolocation tracking, data synchronization, and front-end viz—while also addressing major challenges including signal interference, data privacy and scalability. This review highlights the feasibility and advantages of IoT-based indoor positioning in educational institutions, providing valuable guidance and potential research opportunities for enhancing campus navigation systems..
