Résumé : The GeoNet project will significantly contribute to vehicle communication by implementing a reference specification of a geographic addressing and routing pro- tocol with support for IPv6 to be used to deliver safety messages between cars but also between cars and the roadside infrastructure within a designated destination area. Geographic addressing and routing is a networking mechanism distributing the information to nodes within a designated destination area. A novel routing pro- tocol (C2C NET) is in charge of information dissemination over multiple hops until every vehicle has received this information within the destination area. This docu- ment mentions about basic and advanced features of IPv6 over C2C NET. First, we discover the missing features in current specification of C2C NET and shows some solutions. Second, specification of IPv6 over C2C NET are described and implemen- tation example is investigated in Linux system. Third, we propose advance features such as route optimization, multihoming and simultaneous utilization of NEMO and C2C NET V2V mode.
