Emergency Urgent Communications for Searching Evacuation Route in a Local Disaster

Disastrous accidents (fires, earthquakes, chemical releases, terrorist attacks, indiscriminate gun-shootings, etc.) in local area (urban cities, residential buildings, department stores, etc.) usually result in tragic consequences for people and environments. Such accidents have clearly shown that the necessity for reliable systems supporting evacuation is quite urgent. Particularly choosing safety evacuation route is the most important for persons in affected area. In this paper we propose Emergency Urgent Communication -Evacuation Support (EUC-ES) system based on Mobile Ad-hoc NETworks (MANETs) among many mobile terminals. This system will works anywhere regardless of situations (indoor, urban, basement, etc.) as far as mobile terminals grasp their own positions. From the computer simulation results, it is shown that EUC-ES can evacuate affected persons in safety from the fire which occurred accidentally by using an algorithm to search for evacuation routes.
