The paper outlines a bioinspired approach named "network nervous system" and methods of simulation of infrastructure attacks and protection mechanisms based on this approach. The protection mechanisms based on this approach consist of distributed prosedures of information collection and processing, which coordinate the activities of the main devices of a computer network, identify attacks, and determine nessesary countermeasures. Attacks and protection mechanisms are specified as structural models using a set-theoretic approach. An environment for simulation of protection mechanisms based on the biological metaphor is considered; the experiments demonstrating the effectiveness of the protection mechanisms are described.

Abstract- Port scanning is one of the most popular reconnaissance techniques that many attackers use to profile running services on a potential target before launching an attack. Many port scanning detection mechanisms have been suggested in literature. However, very little work has been done on generating port scanning benchmarks that researchers can use to test their detection methods. In this paper, we suggest a simulation framework using OMNeT++ to generate benchmarks that resemble real-life traffic. We approach the problem by dividing it into three modules (topology creation, good traffic generation, bad traffic generation), each of which we make realistic, similar to deployed and usable networks. Hence the resultant benchmark is annotated and made public.

Orthogonal frequency division multiple access (OFDMA) is a promising technique for high data rate communications in future cellular systems. Since frequency resources are universally reused in every cell in a system, a typical OFDMA system tries to maximize the spectral efficiency. Users located near the cell-edge tend to have the weakest signal strength. So they might experience severe inter-cell interferences (ICIs). In this paper, we propose a sequential frequency reuse (SqFR) that reduces ICIs by a sequential sub-channel allocation. By giving more power to sub-carriers allocated to cell-edge users, our SqFR significantly enhances the performance of cell-edge users. The performance of the proposed SqFR is investigated via the analysis and simulations. Simulation results show that proposed SqFR improves the performance of cell-edge users in

Abstract In order to perform private communication over public networks, such as the Internet, several dif-ferent kinds of virtual overlay networks emerged. Ex-amples are the well known Virtual Private Networks (VPN), Darknets, and anonymizing networks like Tor. All of these networks are designed to provide data de-livery that is confidential, authentic and integrity pro-tected. Nonetheless, for a secure operation also the avail-ability must be taken into account, especially as these structures turn into vital targets for Denial-of-Service (DoS) attacks. Within this article we present metrics to rate differ-ent network topologies with regard to their resistance against botnets, whose available attack bandwidth is not a limiting factor. The presented metrics consider random, greedy, and optimally operating attackers, and are used to derive several properties that very resilient overlay topologies must have. In particular high girth and a low constant node degree were identified and val-idated by simulations.
