U2URelay：自律型UAV間リレーメッシュ＆群制御FANETプロトコル

U2URelayは、自律型無人航空機間（U2U）マルチホップ中継通信を標準化し、災害地域や作戦空域でセルラー網を即座に延伸・自己修復するFANETを構築します。

U2URelay Dynamic Airborne Swarm Mesh Architecture

Distributed geographic routing with predictive kinematic link maintenance

Central System: Reconnaissance Lead Drone - 4K thermal imaging payload with edge bounding box detection

Network Nodes

Reconnaissance Lead Drone
Airborne Relay Node Alpha
Airborne Relay Node Bravo
Tactical Field Base Station

Architectural Protocol Layers

Spaceborne PHY/MAC Layer (3GPP Rel-17 TS 38.300): Doppler compensation, HARQ disabling, and timing advance extension.
Orbital Mesh Routing (CCSDS / Delay-Tolerant Networking): Dynamic topology routing over intermittent laser crosslinks.
Regenerative Core Processing (OpenRAN / 3GPP CU-DU Split): Onboard user plane function (UPF) local breakout.

Key Metrics: < 18ms (LEO Orbit-to-Ground Roundtrip) | 100 Gbps (Optical Crosslink Throughput) | ±48 kHz (Doppler Shift Compensation) | 99.999% (Orbital Constellation Availability)
