     Vehicular Mobility Management for IP-Based Vehicular Networks
          draft-jeong-ipwave-vehicular-mobility-management-05

Abstract

   This document specifies a Vehicular Mobility Management (VMM) scheme
   for IP-based vehicular networks.  The VMM scheme takes advantage of a
   vehicular link model based on a multi-link subnet.  With a vehicle's
   mobility information (e.g., position, speed, acceleration/
   deceleration, and direction) and navigation path (i.e., trajectory),
   it can provide a moving vehicle with proactive and seamless handoff
   along with its trajectory.

1.  Introduction

   This document proposes a mobility management scheme for IP-based
   vehicular networks, called Vehicular Mobility Management (VMM).  The
   VMM is tailored for a vehicular network architecture and a vehicular
   link model described in the IPWAVE problem statement document
   [ID-IPWAVE-PS].

   Vehicle Neighbor Discovery (VND) is proposed as Extended IPv6
   Neighbor Discovery (ND) for IP-based vehicle networks [ID-IPWAVE-VND]
   to support the vehicle-to-vehicle or the vehicle to Road-Side Unit
   (RSU) interactions.  For an efficient IPv6 Stateless Address
   Autoconfiguration (SLAAC) [RFC4862], VND adopts an optimized Address
   Registration using a multihop Duplicate Address Detection (DAD).
   This multihop DAD enables a vehicle to have a unique IP address in a
   multi-link subnet consisting of multiple wireless subnets with the
   same IP prefix, which corresponds to wireless coverage of multiple
   RSUs.  VND also supports IP packet routing over a connected Vehicular
   Ad Hoc Network (VANET) by allowing vehicles to exchange the prefixes
   of their internal networks through their external wireless interface.
