Effects on computer networks due to intentional electromagnetic interference (IEMI) are a well known phenomena. However, when a perturbation occurs in a real world environment the effects may not always be obvious. In case computers crash or reboot repeatedly it is clear that there is a source of malfunction. The same applies to flickering monitors or unpredictable behaviour of input devices. But...
The geomagnetically-induced currents (GIC) on the power grid results from changes of geomagnetic field caused by solar activity, which is the significant problem and needs to be monitored to provide data for disaster analysis. In this paper, we combine with computer networks and communication technologies; develop the Web-based monitoring system for geomagnetically-induced current. The system's background...
This paper realized a serial communication using a pulse counting method. it introduced a call system in which each caller is coded by quasi-digital and the host computer adopts the time-division process and the cyclic query to deal with signal sent by each caller in order to avoid the signal contention, finally it designed the circuit and implement the system. The wired call system is usually applied...
The rapid growth of band requirements for data transmission in computer networks is commonly known. The growth of the network infrastructure in many countries is much slower than expected. Therefore this paper presents some introductory research towards effective and inexpensive algorithmic ways for improving the efficiency of data transmission in all network layers. In this research human behavior...
Computer networks have added new dimensions to the global communication. But intrusions and misuses have always threatened the secured data communication over networks. Consequently, network security has come into issue. Now-a-days intrusion detection systems play an important role in security infrastructures. Intrusions typically start with intruders infiltrating a network through a vulnerable host...
Results of bandwidth challenge contest at Super Computing (SC) 2007 by NICT are discussed. The target of this contest is to make full use of 10 Gbps network for any scientific applications. We, NICT team, attempted to transfer large-scale numerical data at NICT (in Japan) to SC 2007 venue in Reno, USA. We optimized our data transfer system for the real-time computer simulation data, and finally obtained...
This paper deals with the development of computer communication networks in the former COMECON countries between the end of World War II and the beginning of the 1990s.
Coding advantage refers to the potential for network coding to improve end-to-end throughput or reduce routing cost. How large can the coding advantage be? We investigate this fundamental question in the classic undirected network model. So far, all known networks where such potential exists are based on a special class of topologies known as combinatorial networks. We try to prove a rather small...
Biological systems exhibit remarkable adaptation and robustness in the face of widely changing environments. While, current network security researches on bio-inspired are all limited in the layer of human body - immune system. On the basis of current research in bio-inspired domain and aiming at the limitation of these relative research, this paper puts forwards bio-inspired multidimensional network...
