     Vehicular Mobility Management for IP-Based Vehicular Networks
          draft-jeong-ipwave-vehicular-mobility-management-01

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, 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, which is 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 [I-D.IPWAVE-PS].

   To support the interaction between vehicles or between vehicles and
   Rode-Side Units (RSUs), Vehicular Neighbor Discovery (VND) is
   proposed as an enhanced IPv6 Neighbor Discovery (ND) for IP-based
   vehicular networks [I-D.IPWAVE-VND].  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 that consists of multiple wireless
   subnets with the same IP prefix, which corresponds to wireless
   coverage of multiple RSUs.  Also, VND supports IP packet routing via
   a connected Vehicular Ad Hoc Network (VANET) by letting vehicles
   exchange the prefixes of their internal networks through their
   external wireless interface.

   The mobility management in this multi-link subnet needs a new
