U2URelay: Autonomous UAV-to-UAV Relay Mesh & Swarm FANET Protocols

U2URelay standardizes autonomous UAV-to-UAV (U2U) multi-hop relay communications, creating dynamic aerial mesh topologies (FANET) that extend cellular connectivity across disaster zones and military operations.

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)
