Velocity-Affinity Cluster Head Election — Electing stable cluster heads based on speed delta, link duration, antenna height, and battery capacity.
Hierarchical Safety Message Aggregation — Condensing individual vehicle position broadcasts into a single composite polygon stream, reducing spectrum utilization by 75%.
Spatial Channel Reuse & Power Control — Throttling transmission power inside clusters to allow simultaneous concurrent broadcasts on the same 5.9 GHz channel.
