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).
The enhancement of driving safety is one of objectives in cooperative driving in vehicular networks.
Dedicated Short-Range Communications (DSRC) is for vehicular communications .
IEEE has standardized a family standard suite of Wireless Access in Vehicular Environments (WAVE)
. Also, IETF has standardized an IPv6 packet delivery protocol over
IEEE 802.11-OCB (Outside the Context of a Basic Service Set) ,
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 .
With this CAN, a driver can make a better decision on driving to avoid an accident, and an autonomous
vehicle can control its maneuver to escape from a possible fatality in advance.
For this CAN service, this document proposes a light-weight data sharing protocol using a new IPv6 Neighbor
Discovery (ND) option for Vehicle Mobility Information, which is called Vehicle Mobility Information (VMI) option.
This VMI option can be included by a Neighbor Advertisement (NA) message in Vehicular Neighbor Discovery (VND)
.
There are two messages for the CAN service with the VMI option such as Cooperation Context Message
(CCM) and Emergency Context Message (ECM). The CCM is a message to deliver a vehicle's motion information
(e.g., position, speed, acceleration/deceleration, direction) and a driver's driving action (e.g., braking and
accelerating) to its neighboring vehicles for cooperative driving. The ECM is a message to notify a vehicle's
neighboring vehicles of an emergency situation (e.g., an accident and dangerous situation). The ECM has a higher
priority than the CCM such that the ECM needs to be disseminated faster than the CCM in vehicular networks.
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 RFC 2119 .
This document uses the terminology described in .
Vehicle Mobility Information (VMI) option is an IPv6 ND option to convey
either a CCM or ECM.
shows
the format of the VMI option.
A CCM in a VMI option can be included in an NA message that a vehicle transmits
periodically to announce its existence and routing information to its one-hop
neighboring vehicles .
An ECM in a VMI option can be included in an NA message that a vehicle transmits
to immediately announce an emergency situation to its one-hop neighboring
vehicles .
To let the vehicles take an immediate action on an emergency situation, the ECM has a
higher priority than the CCM. Thus, if a vehicle has an ECM and a CCM to send, it
SHOULD transmit the ECM earlier than the CCM.
This document shares all the security issues of the IPv6 ND protocol.
This document can get benefits from Secure Neighbor Discovery (SEND)
in order to protect exchanged messages from
possible security attacks.
