Core Engineering Areas

• GeoBroadcast & GeoAnycast Routing — Addressing messages to physical geographical zones rather than IP addresses, ensuring only relevant oncoming vehicles receive alerts.
• Contention-Based Forwarding (CBF) — Distance-weighted timer algorithms eliminating broadcast storms and packet duplication across multi-lane highways.
• Dynamic VANET Topology Management — Continuous tracking of neighbor tables and link quality in vehicular environments with relative velocities exceeding 300 km/h.
