Fahrzeug-Ad-hoc-Netzwerke (VANET), ETSI GeoNetworking & Mesh-Routing

V2XNet entwickelt die Netzwerkschicht für kooperative Mobilität: ETSI GeoNetworking (EN 302 636), geografische Weiterleitung und Multi-Hop-Routing in 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.
