Redes Ad-Hoc Veiculares (VANET), ETSI GeoNetworking e Roteamento Mesh

V2XNet desenvolve a camada de rede para mobilidade cooperativa: ETSI GeoNetworking (EN 302 636), disseminação geográfica e roteamento multi-hop em VANETs.

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.
