IP Wireless Access in Vehicular Environments (IPWAVE): Problem Statement
and Use Cases
draft-ietf-ipwave-vehicular-networking-12
Abstract
This document discusses the problem statement and use cases of IP-
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, it makes a problem
statement about key aspects in IP-based vehicular networking, such as
IPv6 Neighbor Discovery, Mobility Management, and Security & Privacy.
For each key aspect, this document specifies requirements in IP-based
vehicular networking, and suggests the direction of solutions
satisfying those requirements.

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
