This paper presents an analysis of the RoboCup Rescue Environment tools for simulations based on the firespread phenomenon. Its main purpose is highlighting the features of two simulation tools: the Agent Simulation and the Swarm platform, simulating a fire spread in a particular city. Two simulations had been run using the Agent Simulation unit: one with a model that gives a fire spread that cannot be controlled by the agents and a second one using a model which the agents can control that fire spread, providing an environment and a framework for future studies about the connection between fire spread and collective behavior. Also, this paper shows a theoretical analysis of the Swarm platform and it suggests integration among the tools presented herein. Read More Read Less

Abstract The widespread and increasing application of Particle Swarm Optimizer (PSO) algorithms in both theoretical and practical fields leads to further considerations and new developments for improving its efficiency.

The widespread and increasing application of Particle Swarm Optimizer (PSO) algorithms in both theoretical and practical fields leads to further considerations and new developments for improving its efficiency. To achieve this purpose in this paper a new method is introduced to enhance the convergence rate and reduce the computational time of PSO by combining the PSO including mutation concept (MPSO) and the Hierarchical Particle Swarm Optimizer (HPSO). Therefore the new approach is called MHPSO: a composition of MPSO and HPSO which act simultaneously in the optimization process. In addition some benchmark examples are analyzed using the presented method; consequently, the results are compared to other procedures which illustrate better outcomes and high performance of MHPSO.

Abstract The Better Approach To Mobile Ad-hoc Networking (BATMAN) protocol is designed as an alternative to adhoc network routing protocols such as OLSR. Like most such proposals, BATMAN does not provide any security mechanisms that could limit participation in a specific ad-hoc network. In this article we provide a brief overview of previous work on adhoc network security, identify shortcomings in... The Better Approach To Mobile Ad-hoc Networking (BATMAN) protocol is designed as an alternative to adhoc network routing protocols such as OLSR. Like most such proposals, BATMAN does not provide any security mechanisms that could limit participation in a specific ad-hoc network. In this article we provide a brief overview of previous work on adhoc network security, identify shortcomings in these solutions, and subsequently describe our BatCave security extensions to BATMAN. The BatCave extensions control network participation and prevent unauthorized nodes from influencing network routing. We discuss our prototype implementation and ns-3 simulation results, and suggest options for further work. Read More Read Less

With the advent of globalization and competitiveness all over the world, manufacturing systems are forced to be revised in order to meet three major qualities –data integration, distributed environment and centralized management. To cover the required qualities for the manufacturing systems, Internet based technologies were developed in the last few years. However, even thought collaboration and distributed access in Internet are regularly approached in those technologies; most of the times manufacturing systems do not consider cyber attacks and the inherent security events of the Internet computer systems. The goal of this paper is to propose a Two Stage System for dealing with cyber attacks, which allows: (1) employment of an Event Analysis System for making multi-correlation of security events detected by an Intrusion Detection System and logs from the computer Operational Systems; and (2) applying forecasting techniques on data generated by the Event Analysis Systems to predict future incoming cyber attacks. The obtained results allow concluding about the enhancement of the accuracy regarding forecasts of cyber attacks. Therefore, by anticipating cyber attacks it is possible to improve the manufacturing systems, given by the failure avoidance (considering data integration, distributed environment and centralized management).

Abstract The difficulty of copying an arbitrary quantum state is one of the basic rules governing the physics of quantum systems. Universal Quantum Copying Machine (UQCM) produces two identical copies whose quality is input-state independent. It is evident that the UQCM can be used effectively for the intrustion detection.

Universal Quantum Copying Machine (UQCM) produces two identical copies whose quality is input-state independent. It is evident that the UQCM can be used effectively for the intrustion detection. We have used the isotrophic cloning to study the behavior of the coordinate ratios as a function of the intrusion parameters. As evidenced from this study, there is a strong correlation between the coordinate ratios and the fidelity. Thus, like the fidelity, the coordinate ratios can provide further information on the degree of intrusion. They are also helpful for designing quantum circuits. Read More Read Less
