V2V2I: Extended inter-vehicles to infrastructure communication paradigm
Résumé
We consider the problem of providing ubiquitous IPv6 Internet connectivity to vehicles compliant with IEEE WAVE standard. In particular, we take advantage of two realistic technology trends. On the one hand, IEEE 802.11p interfaces should be mandatory on the On-Board Units (OBUs) but the Road-Side Units (RSUs) deployment will not be immediate. This unavoidable deployment phase slows down the services availability and ITS protocols deployment. On the other hand, car manufacturers have already started equipping their OBUs with 3GPP cellular interfaces (provisioning for LTE) to enable specific car services (remote diagnosis, enter-tainment). We propose to explore the area of inter-vehicles to infrastructure (V2V2I) communication paradigm. We also set fundamental technical requirements enabling IPv6-ready OBUs to access the infrastructure during this deployment phase, and ensure ubiquitous IPv6 Internet access later over LTE. In particular, we compare V2V2I with other vehicular networking models and establish the technical constraints and limits of this paradigm. In order to access the global infrastructure, we satisfy two essential networking requirements for 802.11p-only vehicles: global addresses and specific routes.
