IPv6 Wireless Access in Vehicular Environments (IPWAVE): Problem Statement and Use Cases

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.
