Emergency Mobile Navigation in Hazardous Environment using Wireless Sensor Network

This paper presents a system to provide emergency navigation in hazardous environment using wireless sensor networks and android applications.This system is composed of large-scale deployment of Wireless Sensor Networks which includes Temperature and Gas sensor (WIRELESS SENSOR TECHNOLOGIES) which offers continuous environment monitoring.The incorporation of WSNs into emergency navigation systems aims at navigating people to safe exits by early and automatic detection of potential dangers.It's especially deployed in Gas stations to detect the oil/gas leakages, electrical accidents.The Users must have the emergency navigator application installed on their mobile phones.When emergencies happen, the sensor network explores the emergencies and the mobile users are notified through an SMS alert so that the users can be eventually guided to safe exits through ubiquitous interactions with sensors.It mainly focuses on finding the shortest/safest path for each person, while other sub-optimal (yet safe) paths are left unused throughout most of the evacuation process.Thus this system uses SHORTEST PATH ALGORITHM.Thus the system assists people in escaping from hazardous region quickly when an emergency occurs with guaranteed safety, while avoiding excessive congestions.
