The main topics of vehicular networking are vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), and infrastructure-to-vehicle (I2V) networking. This document deals with some critical aspects in vehicular networking, such as IP address autoconfiguration, vehicular network architecture, routing, mobility management, and security. This document also surveys standard activities for vehicular networks. In addition, this documment surveys the use cases of IP-based vehicular networking for ITS. Finally, this document summarizes and analyzes the previous research activities that use IPv4 or IPv6 for vehicular networking.
