Development of mobile communication framework based on NTMobile

We have been proposing “NTMobile” (Network Traversal with Mobility) that realizes secure connectivity as well as mobility enabling the switching of networks during communication in IPv4 and IPv6 networks. In our conventional implementation method adopted for NTMobile, it has been rather difficult for ordinary users to use it because a kernel module is required to be installed in the smartphone, and as a result, it has been an issue how to popularize NTMobile among ordinary users. In this paper, we propose a mobile communication framework that NTMobile functions are all ported in the level of application, and that provides the basis for developing mobile applications suitable for IPv4 and IPv6 networks. We have implemented our proposed method to a commercially available Android smartphone and an iPhone, and verified the full connectivity and mobility.
