Networks becomes more complex practically in terms of offered services such as electronic commerce. As a result, networks are more and more subject to various kinds of complex security attacks. Existing security system responses have reached their limits in detecting and defending against various network attacks because current attacks are decentralized, automated and intelligent and these syst...

A method for controlling an active power filter using neural networks is presented. Currently, there is an increase of voltage and current harmonics in power systems, caused by nonlinear loads. The active power filters (APFs) are used to compensate the generated harmonics and to correct the load power factor. The proposed control design is a pulse width modulation control (PWM) with two blocks ...

ion). As with Softnet, the messenger system is similar to the capsule approach. It demonstrates that communications protocols can be successfully structured as migrating computations by implementing a sliding window protocol. Further, it shows that with care the resulting programs can be compact enough to be transferred as datagrams. For example, a network discovery program is given in a terse ...

This paper considers a problem of anonymous transmission against eavesdropping and jamming in coherent network coding. A message of n packets is transmitted between some source-receiver pair. An adversary can eavesdrop arbitrary μ packets and inject no more then t malicious packets. The goal is to achieve a communication in such a manner that the adversary can not determine who communicates wit...

The emerging next generation of routers exhibit both high performance and rich functionality, such as support for virtual private networks and QoS. To achieve this, per-flow queuing and fast IP filtering are incorporated into the router hardware. The management of a network comprising such devices and efficient use of the new functionality introduce new challenges. A truly distributed network m...

—Since Distributed Generation (DG) often involves renewable energy, it is important to facilitate integration of DG into existing networks. This is the aim of the EU FP6 demonstration project ADINE. It is based on the Active Network Management (ANM) concept, where automation, ICT and power electronics are used to integrate more DG by exploiting active resources instead of just reinforcing the n...

The IP-based Internet, although wildly successful, is limited in its ability to evolve and adapt, in particular at the network layer. For example, after almost a decade, IP multicast is still not widely available, although applications that might take advantage of its functionality are popular. Mobile/wireless networking is an important emerging area in which adaptivity and evolvability is like...

This paper proposes a wavelet neurocontroller capable of self-adaptation and self-organization for uncertain systems controlled with semi-active devices, ideal candidates for control of large-scale civil structures. A condition on the sliding surface for cantilever-like structures is defined. The issue of applicability of the control solution to largescale civil structures is made the central t...

1 Zbigniew Ogonowski, Silesian University of Technology, 44-100 Gliwice, Akademicka 16, Poland, [email protected] Abstract  The paper presents a concept of network-based learning of Active Noise Control (ANC) problems. Arguments motivating remote experimenting are given. It follows from the presentation that basic experiments can be done automatically using “remote design”. The mo...
