LoRaMoto: A communication system to provide safety awareness among civilians after an earthquake

Civilians in areas hit by earthquakes become particular concerned about the safety of family and friends. However, outages communications networks following these events limit their capacity to get information. So, people drive cars check on loved ones, risking own lives hindering activities first response organizations. This article proposes LoRaMoto, a system that allows civilians exchange information status with others without hampering responders minimizing exposure hazards. Furthermore, exchanged can be aggregated support operations emergency management. LoRaMoto extends LoRaWAN architecture implements packet-forwarding mechanism between end nodes system. helps overcome potential infrastructure blackouts after an earthquake, so it provides awareness when is most needed. We evaluated performance this simulating its use realistic environment, testing baseline configuration, exploring several modifications better understand scalability portability other environments. The simulation results show how meet communication needs civilians, also keep management organizations informed. • A for aftermath earthquake. Users report units receive from others. Simulated district Coquimbo, Chile, affected two during last years. User nodes’ packet forwarding overcomes blackouts. Results fulfill teams.
