New drone V2V protocol enables tactical separation in dense airspace
Sidelink-class C-V2X modules reduce stale-belief divergence by sharing intent in real time
Mehrnaz Sabet's paper presents what is believed to be the first all-airborne, sidelink-class, intent-first V2V tactical neighborhood exchange stack designed for dense Unmanned Aircraft System Traffic Management (UTM). Unlike passive broadcast-only awareness systems, the protocol actively exchanges refreshed state and intent beacons alongside event-triggered messages for yielding, sequencing, release, and contingency coordination. This allows drones to anticipate each other's movements rather than just react, closing the gap between strategic pre-flight planning and last-resort collision avoidance.
The evaluation used scenario-driven, high-volume stress campaigns with real-time, field-anchored C-V2X infrastructure. Results demonstrate that the stack reduces stale-belief divergence, preserves observability through cooperative perception, rejects invalid tactical messages, suppresses false local inference, and structures shared-resource coordination. Performance degrades gracefully under higher density or impairment, transitioning toward guarded fallback. The findings position intent-first aerial V2V as a bounded enabler for scaling tactical coordination in disturbance-driven urban airspace.
- First controller-coupled all-airborne V2V stack using sidelink-class C-V2X modules with authenticated freshness checks
- Reduces stale-belief divergence and preserves observability through cooperative perception in dense drone traffic
- Performs well in lower-to-moderate regimes but transitions to guarded fallback under high density, impairment, or complexity
Why It Matters
Enables scalable tactical coordination for thousands of drones in urban airspace without relying on ground infrastructure.
