IPv6 stateless address auto-configuration in mobile ad hoc network

Abstract

This paper describes global IPv6 address auto-configuration mechanism for MANET(Mobile Ad-hoc Network) nodes connected to the Internet via one or more gateways. IPv6 Duplicate Address Detection(DAD) process cannot be applicable for MANET without modification either because of the multi-hop problem or DAD time bound, In this paper, we propose a stateless autoconfiguration that overcomes multi-hop problem. We solve the multi-hop problem by having some ad-hoc routable nodes doing DAD for the new node that is willing to accept DAD. These auto-configuration steps specifically include generation of link-local address and verification of its uniqueness. It further defines the processes of creating globally routable address and a new duplicate address detection mechanism. Once a host configures its interfaces, it becomes possible to communicate in multi-hop environment. We call this new scheme as Tunneled DAD (T-DAD). © Springer-Verlag Berlin Heidelberg 2006.
