Disaster scenarios require different recovery solutions such as evacuation guidance, to perform the right action for wounded persons and efficiency diffuse useful alert for locating trapped survivors. These latter are constrained mainly by the infrastructure‐less environment caused by the disaster damage (e.g. storm, earthquake). Exploiting opportunistic communications to design recovery solutions presents a promising solution. However, several constraints are encountered, mainly, the multi‐network assortment integrated in mobile equipment and the limited and various battery powers of mobile devices. This work presents a cooperative‐based solution, COPE, that exploits the multi‐network feature of mobile devices and takes the various power levels into account. COPE allows the coverage of a large area for a longer time while guaranteeing an important alert delivery.
