Internet-Draft Problem Statements of IPv6-based Geographic December 2016

Abstract

   For the support of IPv6-based ITS applications, ITS data packets are
   required to be delivered based on the geographical location
   (longitude and latitude) information of the destination ITS node
   or area. Therefore, geographical forwarding mechanisms are preferred
   in the ITS environment. In this draft, we define the issues
   to be considered in delivering IPv6 ITS data based on geographical
   location.

1.  Requirements notation

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in [RFC2119].

   
2.  Introduction

   For the support of IPv6-based ITS (Intelligent Transportation System)
   applications, ITS data packets are required to be delivered based
   on the geographical location (longitude and latitude) information of
   the destination ITS node (e.g., vehicle)or area.
   Since ITS nodes tend to move at high speed, data packet delivery
   based on the IPv6 address may not work efficiently.
   Hence, geographical forwarding (or routing) mechanisms such as
   Greedy Forwarding (GF) [GF] and Contention-Based Forwarding
   (CBF) [CBF] are preferred in the ITS environment.

   In this draft, we define the issues to be considered in delivering
   IPv6 datagrams from a source ITS node to a destination ITS node or
   to the ITS nodes in a given destination area based on
   geographical location.

3. Terminology

   ITS node
      A vehicle or a device that may generate ITS-related data
      in the form of IPv6 datagrams

   Geo-location
      The location of an ITS node represented in the form of
      longitude and latitude. The geo-location information
      is represented in the form of the World Geodetic System 1984
      (WGS84) [WGS-84] formatted coordinates.

   Geographical Forwarding
      IPv6 datagram forwarding based on the geo-location information
      of the source and the destination ITS node or area.
