Validation and evaluation of NEMO in VANET using geographic routing

The combination of geographic-based routing protocols (GeoNetworking) and IPv6 NEtwork MObility (NEMO) into a single communication architecture (IPv6 GeoNetworking) is key in Vehicular Ad-hoc Networks (VANET). While NEMO manages Internet access and session continuity between the vehicle and the Internet, geographically based data forwarding allows an efficient dissemination of the information between vehicles and the infrastructure. In this paper, we refer to the basic scenarios that led to the design of the IPv6 GeoNetworking architecture in the context of the GeoNet project. A prototype implementation of the modules that couple these two technologies is described, in particular the adaptation of IPv6 and C2CNet, a layer that ensures the geographic capabilities. Results of a light experimental performance evaluation are reported.
