Drone Assist Indoor Locating System for Trapped Victim Using Smartphone Application in a 3D Space

When there are large and unaccounted-for numbers of victims in events, fires, or disasters, they are frequently trapped in buildings or wreckage and need to be found and saved as quickly as possible. Given that most people carry smartphones with them when calamities hit, this study turns handsets into interior location tools without requiring further modifications or difficult application installation. This study proposes a method to turn cellphones to a lifesaving tool for stranded victims. In this work, the low power consumption feature of Bluetooth beacons in cellphones is used to deliver Bluetooth signals. For a longer period of time, the signal can keep transmitting, helping rescuers find victims who are stuck. Rescuers might find and pinpoint the location of numerous trapped victims by using a drone and a smartphone app for BLE (Bluetooth Low Energy) detection. By putting this approach in place, the search and rescue team will be able to save more victims who are trapped faster and with less need to visit dangerous locations. In addition, the calling feature on a smartphone might not function during a disaster, and the victim who is trapped might not be strong enough to call for assistance. This technique would make it easier to find them even if they're hidden by falling debris like wood piles or tiles. By reducing the amount of time search and rescue personnel must spend in dangerous areas, this initiative will improve the likelihood of discovering trapped people during the window of opportunity for rescue operations.
