Routerless Fire Evacuation Lighting Guide System using ESP-MDF and Dijkstra Algorithm

A fire incident can pose a great danger to lives and properties. Several solutions including fire evacuation systems exist to solve this problem. These systems employed different controllers, shortest path algorithms and system networks to achieve the desired operations of the system. However, the integration of the Dijkstra algorithm and the routerless WiFi Mesh Network are not yet explored for fire evacuation. Therefore, this study developed a fire evacuation system that could provide the safest path for the evacuees through dynamic signages. This study adopted the Espressif-Mesh Development Framework (ESP-MDF) to connect the system's devices, the capabilities of ESP32 to serve as the brain of each node device and the Dijkstra algorithm to provide the safest path during navigation. As a result, the fire evacuation lighting guide system (FELGS) is accurate in providing the safest path from the initial point to the exit point.
