DT-MANETs for Rescue Information Service

In case of natural or industrial disaster, alert and communication systems become an essential tool for rescue services and a way to inform and to alert population. The traditional communication and alert systems need static infrastructure. Mobiles devices arc now ubiquitous and offer a free support for a spontaneous network. The goal of our project is to perform a delay tolerant network based on mobile devices. In this network mobile nodes are able to transmit data only with their neighborhood. it is an ad-hoc network. It gives no guarantee that a path between any couple of stations can be found. The network used a flooding method to propagate data which is called DFCN -standing for delayed Flooding with Cumulative Neighborhood-. This protocol uses two thresholds for avoiding the well-known "broadcast-storm". This flooding-model gives the ability to self-adapt to the environment when the distribution of devices is unknown and not uniform. In this document we present an experimentation of DFCN on mobile ad-hoc network apply to the risk management.
