A Study on NTMobile that Achieves Both connectivity and Mobility in IPv4 and IPv6 Networks, Noguchi Award, Symposium on Multimedia, Distributed, Cooperative and Mobile Systems (DICOMO2012)
With the spread of mobile networks, connectivity which the beginning of communication is possible between any kinds of networks, and mobility which the switching of networks is possible during communication become quite important matters. We have ...
Recent wireless terminals usually have multiple wireless interfaces, and can switch them to access networks. IP mobility is the technologies that can keep communication when access networks are switched. Most of conventional studies about IP mobil...
With the spread of mobile Internet environment, it is thought that users are going to move to various networks during communication. In this paper, we propose a network architecture called "Network Traversal with Mobility" (NTMobile) that can achi...
For the security measures against threats such as illegal access, etc. it is useful to define and form closed communication groups in order to make communication secure. IPsec is not appropriate in the case where system configurations frequently c...
A NAT traversal problem has to be solved if you access communication devices in a home network from the outside. To solve the problem, we have proposed NAT-free protocol (NAT-f) that creates a NAT mapping dynamically by cooperating with an externa...
Japan has been suffering from a trend in nuclear families, declining birth rate, and growing population of elderly people for a couple of decades. Wandering behavior and solitary deaths of elderly people are recently becoming serious problems in t...
We have been proposing the system, so called TLIFES (Total LIFE Supprt system), which supports the lives of residents utilizing smartphoens. However, TLIFES has the problem of high power consumption because it uses GPS as the key component. In thi...
There is a growing demand for connectivity that ensures the start of communication, regardless of the network environment, and mobility that can continue the communication even if the node switchs its network. We have been proposing Network Traver...
SIP is widely used as the signaling protocol for multimedia communication. However, SIP cannot traverse NAT because it contains IP addresses in message body of IP packets. We have been proposing NTMobile (Network Traversal with Mobility) that can ...
Miniaturization and high performance of wireless sensor devices are progressing in recent years. It is considered that wireless sensor networks will be popular in the future. It is difficult to grasp the configuration of wireless sensor networks, ...
