IP Wireless Access in Vehicular Environments (IPWAVE): Problem Statement
                             and Use Cases
               draft-ietf-ipwave-vehicular-networking-09

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-
