WSN-Visual-Based Fire Detection And Improved Dijkstra Algorithm Forced-Dijkstra For Exit Safe Path

This paper is about developing a php algorithm that sense real time data by a distributed WSN from the area under consideration and uses that information to define the exact location of fire 26 provides the shortest safest path for affected people. This algorithm also sends information immediately to the nearest firefighter center 26 help them to reach the spot for rescue operation using shortest possible path. The area considered to test 26 validate the applicability of algorithm is Elshagra GAS depots in south Khartoum Sudan.This algorithm takes into account all the fired spots 26 predicts level of support needed based on intensity of fire. The algorithm is demonstrated on a scattered wireless sensor network test platform and in simulation. The results of simulations are presented in subsequent sections to demonstrate the applicability of algorithm.
