Fast IPv6 address auto-configuration using proxy for mobile environment

IPv6 stateless address auto-configuration scheme is very useful in mobile environment like as Mobile IPv6 network. Using address auto-configuration, mobile node can configure global address and access Internet when it moves away from home network. In some mobile environment, however, DAD procedure for auto-configuration might not be applicable. For example, in mobile ad-hoc network, DAD procedure using timeout cannot reliably detect the absence of a duplicate address. In this paper, we propose new IPv6 addressing mechanism and address auto-configuration scheme using proxy. A proxy, in our scheme, can allocate global addresses to other IPv6 nodes. Our solution uses a stateful approach, but the solution is lighter and faster than DHCPv6. Our scheme is flexible and efficient, as shown by simulation.
