Multiplayer game for Android platform
Martinák, Andrej ; Bartoň, Radek (referee) ; Žák, Pavel (advisor)
This bachelor thesis deals with issues of real-time multiplayer mobile games development on Android platform. First chapters are devoted to the analysis of this platform and its possibilities of applications development. This is followed by the description of differenent approaches used for multiplayer game development. Part of the thesis describes different technologies, that were analyzed and then used for implementation of a 2D real-time fighting game and a server. The thesis contains the description of the game design, implementation and testing processes of the application.

Implementation of Selected Technology for the Network Trafic Monitoring in Real Environment
Ujhelyiová, Diana ; Sedlák, Petr (referee) ; Ondrák, Viktor (advisor)
The master thesis focuses on the analysis of network traffic monitoring in a selected company and the implementation of selected technology in the real environment. The research is made in the small organization, which does not want to be named and is based in Slovakia. In the theoretical part I deal with basic knowledge - what is information, data and information system. In the practical part, the thesis specifies the company information system - strengths and weaknesses of the organization, risks and proposal of changes to increase the efficiency of work with the company IS.

Analysis of Converged Networks by Simulations
Gardáš, Vít ; Novotný, Bohumil (referee) ; Škorpil, Vladislav (advisor)
The primary purpose of this study is to analyze converged high-speed networks with the usage of Matlab and Simuling. To set problematic area in the field of high-speed networks and solve this problem by creating a model of measurement and simulation of this model. A laboratory exercise is afterwards created on the specific problem.

Generating of flood attacks
Hudec, David ; Hajný, Jan (referee) ; Smékal, David (advisor)
The assessment comprises of two parts, describing theory and generating of flood attacks respectively. The first part covers flood attacks' analysis, deals with their available techniques and practices, known in the area, and a computer simulation program, revealing the behavior of a contested network as well as the attacker's procedure. In the following part, data generating solutions itself are described. These are represented by two hardware programs, adapted from existing solutions, and one C# application, created by the author. The comparison of these two approaches is included, as well as are the generation results and mitigation proposal.

Multimaterial structures preparation by using deposition methods
Novotná, Hana ; Čupera, Jan (referee) ; Řehořek, Lukáš (advisor)
This master’s thesis deals with origin, structure and mechanical properties of architectured material. The theoretical part deals with composits and theory of architectured materials. Further, the cold spray technology is described and it is used to create the network of grooves in the architectured material. In the experimantal part the influence of groof geometry and profil on the mechanical properties of the resulting architectured material is researched. Microstructure and hardness of the samples were also examined.

Wireless sensor network
Ševčík, Martin ; Fedra, Zbyněk (referee) ; Prokopec, Jan (advisor)
This bachelor thesis deal with the ZigBee wireless technology and design of a simple sensor network on its principle. The network is designed for a smaller apartment. As the temperature sensor is used DS1631 thermometer. Communi-cation of the coordinator with the computer ensures XPort®. Used modules from the Meshnetics company integrates the AVR processor and the radio transmitter / receiver at 2.4 GHz operating frequency.

Advanced Utilization of Network Analyzers
Novák, Přemek ; Polívka, Michal (referee) ; Škorpil, Vladislav (advisor)
This bachelor´s thesis consists of description of the laboratory network Cisco and any of its components. Furthermore, the possibility of network analysis according to the standards RFC 2544 and EtherSAM and description of the measurement using analyzer Vepal TX300, Fluke NTS II and Sunlite E1 used in lab reports. In the first task, the characteristics of network elements are analyzing. In the second task, parameters of Cisco network are examined and the third task is focused on the E1 frame.

Inference of DDoS Mitigation Rules
Jacko, Daniel ; Tisovčík, Peter (referee) ; Žádník, Martin (advisor)
This thesis focuses on DDoS attacks, their types and means of their mitigation. The aim of the thesis is to design and implement an algorithm which would be able to derive rules to block DDoS attacks. For this, we chose the algorithm of machine learning, a decision tree, which starts operating as soon as the attack is detected. The algorithm operates with a sample of data detected during the attack, and with a sample of legitimate communication. A part of this thesis is also a description of a BPF format and an overview of executed experiments.
