This document describes how to provide enhanced Internet connectivity
to mobile ad hoc networks. To achieve this goal, we borrow the
concept of Mobile IPv6 and make the most use of available multiple
gateways. Specifically, our scheme makes a global address being used
by Upper layer reachable by peer Internet node by registering another
global address as a locator with corresponding gateway for the
address being cared while the gateway can not obtain host route
information for the cared address because of frequent partitions.
We introduce stateful auto-configuration for acquisition of global
address in mobile ad-hoc networks because it can avoid duplicate
address problem and help prevent traffics from going outside a manet
or unnecessary control traffic by route discovery of reactive routing
protocols from being issued. In addition, it can support for our
scheme since our scheme requires some security guarantee to register
a locator with a gateway as Mobile IPv6 requires for Binding Updates.
Basically, our extended support and stateful configuration of global
address are devised to extend AODV, but the concept is also
applicable for proactive routing protocols such as OLSR, TBRPF.
Further, our extended support can be useful for a mobile node(MN) in
Mobile IPv6 to maintain its reachability from the Internet by
utilizing multi-hop manet extension as a virtual link since it can
help determine intelligently when current CoA should be changed and
Binding Update with new CoA be performed while it can make the
current CoA reachable from Internet even when the GW which assigned
the CoA is not reachable from the manet node any more.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
