Participatory sensing for emergency communication via MANET

Most large-scale disasters are characterized by breakdown of essential communication systems. The failure of telecommunication system reduces the pace of emergency response and relief efforts. The paper is confined mainly on how communication can be carried even when a cellular network is down. The proposed system designs a participatory system for emergency communication. The existing participatory sensing systems have not addressed the issues arising when an area is hit with a disaster. By creating mobile ad hoc network of smart phones, it would be possible to allow messages requesting help to pass between phones until they are intercepted by a node which can directly connect to the cellular network or internet. An algorithm for routing the message in such a network is presented. It also showcases an android application called Android app for Emergency Communication (AEC) which would perform this task.
