Design of Generalized Powertrain Model
Borkovec, Tomáš ; Kenyeres, Martin (referee) ; Škorpil, Vladislav (advisor)
In this work is proposed the generalized powertrain of the parallel hybrid car. The powertrain is composed from the sub-models of the power sources. Each sub-model is described by the quasi-static modeling. For given routes is computed the power demand. Based on the derived power demand, three energy management systems are tested. First system is based on heuristic rules. The second one use more sophisticated control algorithms - the optimization method. Main idea is based on minimum principle, when the control algorithm tries to minimize the cost function (fuel use, emission). The last one is based on the equivalent consumption minimization strategy.

Analysis and Improvement of Distributed Systems
Kenyeres, Martin ; Sýkora, Jiří (referee) ; Klučik,, Stanislav (referee) ; Škorpil, Vladislav (advisor)
A significant progress in the evolution of the computer systems and their interconnection over the past 70 years has allowed replacing the frequently used centralized architectures with the highly distributed ones, formed by independent entities fulfilling specific functionalities as one user-intransparent unit. This has resulted in an intense scientic interest in distributed algorithms and their frequent implementation into real systems. Especially, distributed algorithms for multi-sensor data fusion, ensuring an enhanced QoS of executed applications, find a wide usage. This doctoral thesis addresses an optimization and an analysis of the distributed systems, namely the distributed consensus-based algorithms for an aggregate function estimation (primarily, my attention is focused on a mean estimation). The first section is concerned with a theoretical background of the distributed systems, their evolution, their architectures, and a comparison with the centralized systems (i.e. their advantages/disadvantages). The second chapter deals with multi-sensor data fusion, its application, the classification of the distributed estimation techniques, their mathematical modeling, and frequently quoted algorithms for distributed averaging (e.g. protocol Push-Sum, Metropolis-Hastings weights, Best Constant weights etc.). The practical part is focused on mechanisms for an optimization of the distributed systems, the proposal of novel algorithms and complements for the distributed systems, their analysis, and comparative studies in terms of such as the convergence rate, the estimation precision, the robustness, the applicability to real systems etc.

Ad Hoc Network Scenarios and Different Types of Attacks
Rexa, Denis ; Kenyeres, Martin (referee) ; Škorpil, Vladislav (advisor)
V tejto semestrálnej práci venovanej sieťam MANET a ich bezpečnostným hrozbám sa v prvej časti preberajú a porovnávajú smerovacie protokoly AODV vs OLSR vs ZRP. Ďalej je spomínaný broadcast storm a podrobnejšie rozobrané základné typy útokov v sieťach MANET s návrhmi na potlačenie vplyvu na fungovanie siete. V nasledujúcej kapitole je ukazané a popisané prostredie NS-3 simulátora s uvedeným jednoduchým programom a spôsobmi, ako získať údaje. Posledná kapitola ukazuje vplyv black-hole útoku na sieť a návrh na jej elimináciu.

Simulation and Optimization of Converged Networks Traffic
Turan, Jonáš ; Kenyeres, Martin (referee) ; Škorpil, Vladislav (advisor)
The aim of this work is to explore and describe possibilities of the network simulator OMNeT++, to create a user guide using this knowledge and make three tasks for computer exercise. In the first part, the principle and functionality of OMNeT++ are described theoretically, there are possibilities and area of focus. User guide can be used for basic understanding of the system. There is a description of the environment, the file composition and the basic operations. Individual tasks are focused on implementing technology DiffServ, RIP and OSPF. The goal of student is to assemble a simulation and learn basic functions of OMNeT++ and then evaluate the results.

Protocols Analysis of CISCO Networks
Karlík, Martin ; Kenyeres, Martin (referee) ; Škorpil, Vladislav (advisor)
ABSTRACT Bc.Karlík, Martin Department of Telecommunications, Faculty of Electrical Engineering and Communication, Brno University of Technology. Analysis of CISCO networking protocols This semestral thesis is focused on CISCO networks and protocols like MPLS, BGP, Ipv4, Ipv6, Multicast – sprase / dense mode. The task was study of those protocols and design and implement lab excercise with one of those protocols by using free network simulator GNS3. In this excercise is used CISCO router 3745.

Communication Server Design and Implementation
Sedláček, Robert ; Kenyeres, Martin (referee) ; Škorpil, Vladislav (advisor)
In the first part of this work, there is analysis of the industrial proprietary protocol S7 by Siemens. The analysis is performed by Wireshark between the programmable controller S7-1200 and Simatic NET OPC server. This protocol is based on other protocols whose proposals and solutions are completely or at least partially described in this work. On the basis of this information is created a communication library in C ++, which allows the transmission of variables. This library is subsequently used in the implementation of the communication server through which one can easily access variables in the programmable machine with a text protocol.
