Vehicular Mobility Management for IP-Based Vehicular Networks
draft-jeong-ipwave-vehicular-mobility-management-01
Abstract
This document specifies a Vehicular Mobility Management (VMM) scheme
for IP-based vehicular networks. The VMM scheme takes advantage of a
vehicular link model based on a multi-link subnet. With a vehicle's
mobility information (e.g., position, speed, and direction) and
navigation path (i.e., trajectory), it can provide a moving vehicle
with proactive and seamless handoff along with its trajectory.

1. Introduction
This document proposes a mobility management scheme for IP-based
vehicular networks, which is called Vehicular Mobility Management
(VMM). The VMM is tailored for a vehicular network architecture and
a vehicular link model described in the IPWAVE problem statement
document [I-D.IPWAVE-PS].
To support the interaction between vehicles or between vehicles and
Rode-Side Units (RSUs), Vehicular Neighbor Discovery (VND) is
proposed as an enhanced IPv6 Neighbor Discovery (ND) for IP-based
vehicular networks [I-D.IPWAVE-VND]. For an efficient IPv6 Stateless
Address Autoconfiguration (SLAAC) [RFC4862], VND adopts an optimized
Address Registration using a multihop Duplicate Address Detection
(DAD). This multihop DAD enables a vehicle to have a unique IP
address in a multi-link subnet that consists of multiple wireless
subnets with the same IP prefix, which corresponds to wireless
coverage of multiple RSUs. Also, VND supports IP packet routing via
a connected Vehicular Ad Hoc Network (VANET) by letting vehicles
exchange the prefixes of their internal networks through their
external wireless interface.
The mobility management in this multi-link subnet needs a new
