        IPv6 Neighbor Discovery for IP-Based Vehicular Networks
           draft-xiang-ipwave-vehicular-neighbor-discovery-00

Abstract

   This document specifies a Vehicular Neighbor Discovery (VND) as an
   extension of IPv6 Neighbor Discovery (ND) for IP-based vehicular
   networks.  An optimized Address Registration and a multihop Duplicate
   Address Detection (DAD) mechanism are established for both operation
   efficiency and the saving of wireless bandwidth and vehicle energy.
   Also, the two new ND options for a rapid prefix and service discovery
   are used to announce the network prefixes and services inside a
   vehicle (i.e., a vehicle's internal network).  Finally, a mobility
   management scheme is proposed for moving vehicles in vehicular
   environments to support seamless communication for the continuity of
   transport-layer sessions (e.g., TCP connections).

1.  Introduction

   Vehicular Ad Hoc Networks (VANET) have been researched for
   Intelligent Transportation System (ITS) such as driving safety,
   efficient driving and entertainment.  Considering the high-speed
   mobility of vehicular network based on Dedicated Short-Range
   Communications (DSRC), IEEE 802.11p [IEEE-802.11p] has been
