Ad-hoc network recovery after severe disaster

In this paper, a method of recovering communication after a disaster is presented. It consists in spreading in the area access points, using drones for examples. The access points allow persons who have personal phones with wireless connection capability, to communicate via these access points. The access points form a wireless mesh network which enable access to gate ways that remained after the disaster in the neighborhood of the disaster are or gate ways that can be added after the disaster. The reliability of such a system is analysed.
