This talk presents the current status of R&D on New Generation Network (NWGN) in Japan which is expected to be developed until 2020 as a network beyond the Internet and Next Generation Network (NGN). Social and technological requirements for NWGN and ...

Communication networks have advanced in many respects and to levels where they can provide revolutionary capabilities in every business, governmental and societal sectors. In spite of present successes and achievements, there are many remaining ...

The Internet research community has in recent years taken a renewed interest in the long-standing global Internet routing scaling problem. Much of this research has taken the form of much-needed "clean-slate" research, where ideas are pursued ...

Society increasingly relies on computer networks in general, and the Internet in particular. Consumers rely on networks for access to information and services, personal finance, and for communication with others. The Internet has become indispensable to ...

Frequently, complex systems in nature as well as in human society suffer massive catastrophes triggered from only a small fraction of their constituents. Unexpected epidemic spread of diseases, the power outage, and the congestion of packet transport in ...

Researchers have been proposing new protocols and services to improve performance, reliability, and scalability of the Internet. There have been several testbed platforms to test such protocols and services. In this paper, as an approach to develop a ...

In this paper, we formulate the virtual network embedding problem in wireless networks and suggest a framework to approach the problem. Also, we show an application of our problem modeling framework with ORBIT which is one of famous wireless test-bed ...

Besides a more widespread sensitivity to ecological issues, the interest in energy-efficient network technologies springs from heavy and critical economic needs, since both energy cost and network electrical requirements show a continuous growth, with ...

Utilization of multiple radio interfaces increases throughput of wireless networks. Existing work proposes a multi-radio routing protocol exploiting link quality and channel diversity of a path. While an established path is deteriorated by interferences ...

Future Internet is expected to evolve towards user-centric paradigms, which leverage ubiquitous and pervasive communications.

Mobility will be one of the key issues in such evolution. Current mobility protocols have a number of limitations and drawbacks;...

It is envisioned that the future Internet environment consists of a variety of mobile/wireless networks with the rapidly increasing number of mobile users. This paper discusses some visions and issues on the design of the mobile optimized future ...

As the Internet evolves into an irreplaceable service infrastructure for modern human life, a key issue to consider is that of creating and managing a rich variety of services while keeping aware of individual requirements with guaranteed QoS (Quality ...

Content routing is aimed to provide location-independent access to an object without relying on the maintenance of network connections between the source and the destination of the object. This paradigm enables the usage patterns in terms of ...

WiFi-based location based services (LBSs) are expected to be more and more pervasive in future Internet. In WiFi networks, a virtual network database (VNDB), which maintains the estimated locations of access points (APs), should be constructed for the ...

As providing data networks in an urban district through a cellular system is expensive and does not provide sufficient capacity, use of a wireless mesh network is generally considered as a way to achieve more capacity. While a mesh network has sizable ...

One of the key messages in significant research on cross-layer design of wireless networks over the past 15 years is that extensive message passing may be necessary to achieve optimal performance. Heavy message passing is obviously an undesirable ...

Today wireless local area networks (WLAN) are evolving with an aim to enhance the throughput performance leveraging various cutting-edge technologies. In this paper, we compare the aggregate throughput performance of two different multi-channel access ...

In this paper, we present the integrated video transmission system that is suitable for future internet environment. The goal of the proposed system is to provide a stable video streaming service over heterogeneous networks. First, we investigate what ...

In this paper, we investigate the problem coming from the adaptation of legacy protocol TCP to the cross-layer protocols that is likely happen in future Internet. We point out named a TCP starvation problem in combining TCP and max-weight scheduling of ...

BGP is the most important component of Internet routing and yet it is vulnerable to many threats such as IP prefix hijacking, which has created significant problems over the decade. There have been two approaches to address the IP prefix hijacking issue:...

A group key management is essential scheme guaranteeing data confidentiality in multicast. To provide the strict secrecy in group communication, the rekeying delay has to be minimized. In this paper, we propose a new group key management protocol, ...
