    Context-Aware Navigator Protocol for IP-Based Vehicular Networks
             draft-jeong-ipwave-context-aware-navigator-01

Abstract

   This document proposes a Context-Aware Navigator Protocol (CAN) for
   IP-based vehicular networks for cooperative navigation among vehicles
   in road networks.  This CAN aims at the enhancement of driving safety
   through a light-weight driving information sharing method.  The CAN
   protocol uses an IPv6 Neighbor Discovery (ND) option to convey
   driving information such as a vehicle's position, speed,
   acceleration/deceleration, and direction, and a driver's driving
   action (e.g., braking and accelerating).

1.  Introduction

   The enhancement of driving safety is one of objectives in cooperative
   driving in vehicular networks.  Dedicated Short-Range Communications
   (DSRC) is for vehicular communications [DSRC].  IEEE has standardized
   a family standard suite of Wireless Access in Vehicular Environments
   (WAVE) [WAVE].  Also, IETF has standardized an IPv6 packet delivery
   protocol over IEEE 802.11-OCB (Outside the Context of a Basic Service
   Set) [RFC8691], which is a MAC protocol for vehicles in WAVE.

   A vehicle equipped with various sensors and the a DSRC device can
   sense its surrounding environment including its neighboring vehicles,
   and share the sensed data and its mobility information (e.g.,
   position, speed, acceleration/deceleration, and direction) with its
   neighboring vehicles.  This information sharing allows vehicles to
   assess the collision risk and make their maneuver change to avoid an
   accident in a prompt way.  That is, the capability of sensing,
   computing, and communication of vehicles enables them to understand
   the driving environment and situation (i.e., context), and cooperate
   with each other during their navigation.

   The driving information sharing enables Context-Aware Navigator (CAN)
   where each vehicle can display its neighboring vehicles, pedestrians,
   and obstacles in its navigation system [CASD].  With this CAN, a
   driver can make a better decision on driving to avoid an accident,
