A Network Mobility Management Architecture for IPv4 and IPv6 Environments

The current design of Network Mobility(NEMO) basic protocols doesn't provide the compatibility between networks of different versions. However, we need the scheme supporting seamless mobility between IPv4 and IPv6 networks because the coexistence between the two networks is expected in future internet. So, in this paper, we propose a new architecture for the network mobility through a Tunnel Agent(TA) managing NEMO Tunnels when a Mobile Router(MR) moves from IPv6 to IPv4 networks.
