As uncrewed delivery drones and air taxis ramp to thousands of hourly flights over metropolitan centers, centralized cloud servers introduce intolerable latency. This paper introduces a distributed edge gateway architecture executing 4D geometric deconfliction in under 5 milliseconds.
By indexing airspace into 10-meter voxel hierarchies, collision avoidance queries scale logarithmically, enabling instant pairwise distance calculations between 10,000 active trajectories.
Stress-testing the gateway with 50,000 simulated simultaneous drone delivery legs demonstrated zero near-mid-air collisions (NMAC) and a 99.999% message delivery success rate over direct C-V2X sidelink.
