PREVENTING CHILD DISORIENTATION AND ENSURING SAFETY IN MULTI-STORY MEGA-STRUCTURES

ABSTRACT: Indoor structures such as walls and roofs weaken GPS signals, making it impossible to rely on conventional outdoor navigation methods in indoor environments because it doesn't produce reliable results. The use of Bluetooth beacons to determine the user's location and assist the user in navigating from one point to another is proposed in this paper. By strategically placing beacons inside large buildings like malls and hospitals, it becomes possible to accurately detect a Persons location and facilitate navigation from one point to another within the building. The paper also proposes a service that identifies crowd density inside the building, helping users navigate more efficiently through the complex. The location is determined using the trilateration technique, and suggested the route is calculated based on nearby points of interest or tenants. Dijkstra's algorithm is used for navigation. In this experiment, the sensors and wifi access points transmit signals to a cloud server, helping to prevent users, especially children, from getting disoriented in large multi-story buildings, thereby ensuring their safety.
