Disseminating shared information in disaster relief efforts: A communication computable model

VHF radio systems commonly used to support search and rescue activities after disasters limit the flow of information among response teams deployed in the field. It generates islands of information that jeopardizes the coordination and effectiveness of the response activities. This article proposes a communication model that uses opportunistic networks and real-time messages delivery to help address such limitation. Since the communication model is computable, it is possible to diagnose the flow of information expected for a particular work scenario. The diagnose results allow identifying elements that could help improve the information flow in such scenario. This proposal allows first responders to address the stated problem during the phases of preparedness, response and recovery from a disaster.
