Abstract

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.
