One idea is to employ fully autonomous air crafts. That is, using unmanned and not remotely piloted aerial vehicles as a means of mass transit. Clearly, fully autonomous air taxis constitute a safety critical, time sensitive application. Efficient information management is a prominent requirement and the infrastructure for sensing and fast, reliable communication is the key to mitigate any harm in the aforesaid approach. Nevertheless, failures in such a system are inevitable and need to be addressed. This work investigates the significant aspect of building a fault-tolerant UAM communication network. We introduce a concept of distributed ground station architecture and a protocol for role delegation to improve system availability. This assures an uninterrupted service continuation fulfilling the high standards of safety requirements in an UAM system.encommunicationfault toleranceUAMCommerce, Communications, TransportConference Paper10.1109/DCOSS-IoT58021.2023.00102Conference Paper
