        IPv6 Neighbor Discovery for IP-Based Vehicular Networks
           draft-jeong-ipwave-vehicular-neighbor-discovery-05

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 three new ND options for prefix discovery, service
   discovery, and mobility information report 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).
