A Literature Review On Indoor Localization and Navigation for Campus

Abstract

This project explores the design and implementation of 
an offline, cross-platform indoor navigation system for college 
campuses, inspired by recent advances in location-based services, 
mobile notifications, and smart campus assistance. Integrating 
concepts from Firebase-based mobile app control, notification- 
driven scheduling, and seamless indoor localization systems, our 
solution uses annotated SVG maps to construct an efficient graph
based navigation model. The application, built in Flutter, parses 
these SVGs to identify key navigational nodes and edges 
representing rooms, walkways, and floor transitions. Using A* for 
route computation, the app provides optimal paths between any 
two points while functioning entirely offline. Features like 
dynamic rerouting and multi-floor handling enhance usability, 
and the system leverages Flutter’s rendering capabilities for 
interactive map overlays. This project demonstrates how modern 
mobile technologies can offer efficient, and user-friendly indoor 
navigation solutions for educational institutions.
