Short-Term Mobile Ad Hoc Network with LoRa Based Infrastructure in Disaster Relief

The network infrastructure suffers severe destruction when disaster strikes. As a result, the primary network powered by the electric grid is most likely destroyed. It makes communication between the victims and the rescue team much more difficult. This paper reviews past research to explore how different solutions can be rapidly deployed for disaster relief procedures. The research aims to provide a temporary network infrastructure to connect the victims during the disaster to speed up relief operations and provide alternative means to obtain data in a rescue process. The proposed solution takes advantage of how people nowadays carry their phones in their hands most of the time. A novel solution is suggested to use the mobile phone to connect to LoRa-powered nodes to transmit information. LoRa powers the nodes to maximise the efficiency and coverage area.
