      Vehicular Neighbor Discovery for IP-Based Vehicular Networks
           draft-jeong-ipwave-vehicular-neighbor-discovery-08

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 performed for having operation
   efficiency and also saving both wireless bandwidth and vehicle
   energy.  Also, three new ND options for prefix discovery, service
   discovery, and mobility information report are defined to announce
   the network prefixes and services inside a vehicle (i.e., a vehicle's
   internal network).
