LoRa comes with characteristics beneficial in crisis situations, like its long range and the low power consumption, which allows to run running devices on batteries significantly longer than, e.g., cellular base stations. However, LoRaWAN does not benefit from these characteristics, as it depends on a centralized, cloud-based network server infrastructure. If gateways can no longer access the backing network, forwarding stops and the network fails in the affected region. This thesis investigates collaboration between gateways to transparently forward frames from LoRaWAN devices in regions suffering from an outage of the backing network.
