Power line grid model
Csiba, Patrik ; Sláčik, Ján (referee) ; Mlýnek, Petr (advisor)
This diploma thesis analyzes the PLC communications in various scenarios. The first part of the thesis describes the principle of narrowband and broadband communication and the analysis of electrical lines. The next part describes the NS-3 framework, simulation scenarios for establishment the effect of branches and other parameters on the baud rate. The last part determines the minimum number of repeaters and their location on the extended topology.

Extension and renovation of communication network in the area of high school
Valný, Jakub ; Sedlák, Petr (referee) ; Novotný, Vít (advisor)
The bachelor's thesis deals with a proposal for the expansion and modernization of a computer network in the high school building. The analytical part of the work describes the current state of the computer network, the building itself and the requirements of the investor. The theoretical part of the thesis describes the information needed to develop the design itself. The design section describes my own project elaboration. The last part of this work is the economic evaluation of the proposal.

Using OMNeT++ simulator in teaching telecommunication technologies
Jalůvka, Jiří ; Zeman, Václav (referee) ; Novotný, Vít (advisor)
Main goal of this thesis is to familiarize with possibilities in simulating environment OMNeT++ with use of pre-integrated models or models imported from INET Framework. Simulated LAN networks created by 802.3 standard (ethernet) and 802.11 (Wi-Fi) will be performed in this simulation environment. In such networks, data traffic will be created at the application layer (video streaming, telnet, etc.) using the TCP and UDP transport protocol. For the UDP transport protocol graph will show a delay between end-to-end network elements in the first and second example and a jitter grap in the second practical example. For the TCP transport protocol will be performed „three-way handshake process“. Also, multi-way signal spread is shown by 802.11 standard.

Simulation of data networks in OMNeT++
Závodný, Ondřej ; Novotný, Vít (referee) ; Skořepa, Michal (advisor)
The content of this work is to research possibilities of simulation data networks in a simulating environment OMNeT++ with INET framework and at observance of standards 802.3 (ethernet) and 802.11 (Wi-Fi).\ In a given environment will be simulated handover in a Wi-Fi network and on the second layer of the reference model ISO/OSI. In this example will be processed visualization of the conditions and sending informations between network elements.\ In the next practical example will be simulated the operation on the application layer (video current, ftp communication) at using a relevant transport protocols (UDP,TCP). For routing between network elements will be utilized configuration files. By transport protocol UDP will be displayed a delay graph between final elements and jitter, by TCP protocol will be represented so-called three-way-handshake.

Network data traffic analysis and modeling
Šabatka, Zdeněk ; Molnár, Karol (referee) ; Růčka, Lukáš (advisor)
This bachelor's thesis is focused on analysis of network traffic and its modeling. In the thesis, there are described various methods of traffic modeling, both current and modern, and historical, for contemporary traffic inconvenient. The first part is focused on the theoretical analysis of these models, there are also mentioned basis formulas. In the second part, practical, there is capcured real WWW traffic. In the last part, that real network traffic is modeled using Markov model.

The current possibilities of data networks
Pavelka, Jakub ; Vaněk, Jiří (advisor) ; Vladimír, Vladimír (referee)
The thesis is focused on mapping issues when creating data networks. Overview solved problems briefly introduces the history and classification networks. Continues characteristics of active and passive parts of the network where it connects certification, ending a general guide for network architects, which can be used to understand the theory of progress in the design and implementation of data networks with regard to its functionality and reliability. This section explaining how the proposal looks like a LAN, which is one of the most widespread types of networks, and most standards it is just related. The practical part is focused on the demonstration of a possible case design, including its economic parameters. The various alternatives are worked out with regard to the choice of materials offered different levels of quality and possible types of treatment for the future. The alternatives are as follows economically analyzed and evaluated.
