IPv6 Wireless Access in Vehicular Environments (IPWAVE): Problem
Statement and Use Cases
draft-ietf-ipwave-vehicular-networking-19
Abstract
This document discusses the problem statement and use cases of
IPv6-based vehicular networking for Intelligent Transportation
Systems (ITS). The main scenarios of vehicular communications are
vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), and
vehicle-to-everything (V2X) communications. First, this document
explains use cases using V2V, V2I, and V2X networking. Next, for
IPv6-based vehicular networks, it makes a gap analysis of current
IPv6 protocols (e.g., IPv6 Neighbor Discovery, Mobility Management,
and Security & Privacy), and then lists up requirements for the
extensions of those IPv6 protocols for IPv6-based vehicular
networking.

1. Introduction
Vehicular networking studies have mainly focused on improving safety
and efficiency, and also enabling entertainment in vehicular
networks. The Federal Communications Commission (FCC) in the US
allocated wireless channels for Dedicated Short-Range Communications
(DSRC) [DSRC] in the Intelligent Transportation Systems (ITS) with
the frequency band of 5.850 - 5.925 GHz (i.e., 5.9 GHz band). DSRC-
based wireless communications can support vehicle-to-vehicle (V2V),
vehicle-to-infrastructure (V2I), and vehicle-to-everything (V2X)
networking. The European Union (EU) allocated radio spectrum for
safety-related and non-safety-related applications of ITS with the
