IPv6 stateless address auto-configuration in mobile ad-hoc network (T-DAD) and performance evaluation

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 auto-configuration 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. 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).

IPv6 stateless address auto-configuration in mobile ad-hoc network

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 auto-configuration 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).

Distributed IPv6 addressing technique for mobile ad-hoc networks

Connecting to the Internet through the nodes of an ad-hoc network is very challenging and necessary. We studied a MANET topology in which all nodes in this MANET need to be connected to the Internet through a special node called the Internet Gateway. Traditional IPv6 Duplicate address Detection(DAD) process cannot be applied for this topology without any modification. In this paper, we propose a stateful IPv6 auto-configuration scheme that can replace DHCPv6 for ad-hoc networks. Our simulation shows that this scheme is lighter and faster than DHCPv6.
