We report from experiments with wireless and mobile computing at the University of Oslo, NORWAY. We have established a wireless Experimental Metropolitan Area Network (WEMAN), based on Mobile IPv6 for mobility and IEEE 802.11 technology for wireless links and access.. WEMAN is a wireless extension of the IPv6 based Internet 2 in Norway, and enables flexible access for nomadic and mobile users. ...

In this paper, we propose a Metropolitan Area Network which is a two level optical star Network. The stations are grouped into clusters based on geographical proximity and communication demands. The stations within a cluster communicate using a local WDM star network and a station in one cluster communicates to a station in another cluster through a remote star in single hop. The multiwavelengt...

L Introduction Large-scale public systems in today’s information control field require. that seveml conditions should be satisfied. Fmt, a phased-in construction of the system must be possible so that the system can be constructed over a long period of time. Second the system must be flexible and be adapted to meet the changes of social needs. All such systems are assumed to constantly grow, ex...

Fibre Channel Over TCP/IP (FCIP) describes mechanisms that allow the interconnection of islands of Fibre Channel storage area networks over IP-based networks to form a unified storage area network in a single Fibre Channel fabric. FCIP relies on IP-based network services to provide the connectivity between the storage area network islands over local area networks, metropolitan area networks, or...

A wide area network (WAN) is a communications network utilizing devices such as telephone lines, satellite dishes, antennas, and microwaves to span a larger geographic area than can be covered by a local area network (LAN). Typically, a WAN consists of two or more LANs. A metropolitan area network, or MAN, is a term sometimes used to describe a system that falls somewhere between a WAN and LAN ...

An understanding of epidemiological dynamics is important for prevention and control of epidemic outbreaks. However, previous studies tend to focus only on specific areas, indicating that application to another area or intervention strategy requires a similar time-consuming simulation. Here, we study the epidemic dynamics of the disease-spread over a commute network, using the Tokyo metropolita...
