Technical analysis and engineering reference.
Unlike Mobile Ad-Hoc Networks (MANETs) formed by ground vehicles or pedestrians, Flying Ad-Hoc Networks (FANETs) exhibit extreme node velocity (often exceeding 100 km/h), rapid three-dimensional topological fluctuations, and severe multi-path Doppler shifts. A sudden roll or pitch maneuver can cause an onboard blade antenna to be shaded by carbon-fiber wings, breaking peer links in milliseconds.
U2URelay deploys cross-layer information sharing between the autopilot flight computer and the networking layer: - The routing daemon subscribes to internal inertial measurement unit (IMU) telemetry (accelerometers, gyroscopes, and GPS heading). - If an aircraft begins an evasive 60-degree banked turn, the networking layer immediately transfers active packet flows to a secondary antenna or reroutes packets through a trailing drone. - Packet buffer sizes are dynamically tuned to match instantaneous inter-drone line-of-sight probabilities.
In massive wildfire response operations where cellular towers are destroyed, a fleet of six autonomous drones deploys along mountain ridges, creating a 50-kilometer broadband relay corridor that streams real-time thermal hotspot video directly to firefighter handheld terminals.
