An Android Application for Opportunistic Alert Diffusion in Disaster Scenario

Abstract : —Opportunistic communications present a promising solution as a disaster network recovery in emergency situations such as hurricanes, earthquakes and floods where infrastructure might be damaged. We have proposed COPE, a cooperative opportunistic alert diffusion scheme useful for trapped survivors during disaster scenarios to report their position and ease their rescue operation. It targets to maintain mobile devices alive as long as possible for a maximum network coverage until reaching proximate rescuers. Unlike existing opportunistic-based disaster recovery solutions, COPE deals with mobile devices that come with an assortment of networks and aims to perform a systematic network interface selection. Furthermore , it considers mobile devices with various energy levels and allows low-energy nodes to hold their charge for longer time with the support of high-energy nodes. This work presents a proof-of-concept implementation of COPE for Android smartphones. Our demo contribution exploits smartphones equipped with two short-range communication technologies (i.e. Bluetooth and Wi-Fi) and takes the various energy levels into account. As rescue operation might take long time and in order to preserve the battery power, smartphones form cliques with neighboring nodes based on the low-energy network interface Bluetooth. Afterwards, smartphones, belonging to the same clique, cooperate alternately to perform an alert diffusion based on the Wi-Fi network interface.
