Implementation and evaluation of NTMobile with Android smartphones in IPv4/IPv6 networks

We have been proposing a new IP mobility technology, called “Network Traversal with Mobility” (NTMobile), that solves the NAT traversal problem and provides flexible mobility in IPv4 and IPv6 networks at the same time. In this paper, we have implemented the NTMobile functions in an Android smartphone and performance evaluated in the IPv4 and IPv6 networks. It was confirmed that the NTMobile-compatible nodes can establish a connection with the correspondent node and move between IPv4 and IPv6 networks with low latency.
