It is not future story that host mobility in wireless network. We already have many devices which can access network among moving our locations. Internet protocol is extended to support not only host mobility but also network mobility. But nesting mobile networks and mobile hosts, there is a problem that routing path of packet becomes complex. By sequential tunneling on outgoing packet at mobile router and toward mobile network at correspondent node, it can be setting up direct path in nested mobile network environment. In this paper, we propose a method for delivering packet through optimized path by sequential tunneling. And evaluate this method by equations and simulations.
