Development of evaluation model of MANET in NS-3 environment
Gilík, Aleš ; Vajsar, Pavel (referee) ; Hošek, Jiří (advisor)
This bachelor thesis is focused on Manet networks and creation of web application for generate configuration file which is simplifying simulation of Manet networks. The theoretical part concerns with description of Manet networks, distribution of routing protocols and closer look on five of the protocols. In the next part is described simulator Ns-3 with his content for simulations. The practical part is describing creation of configuration file and his elements. For that was created web application in PHP language. All used technologies for creation of the application are described in this thesis. The web application is fully processed and operational.

Modelling of network communication in OPNET IT Guru environment
Mazák, Andrej ; Škorpil, Vladislav (referee) ; Hošek, Jiří (advisor)
The aim of this work is to describe modeling of network communication with the given network performance and load. The selected model of network approaches the real network topology of a telecommunication operator that provides network services for the customers. We take a closer look on the functions of the significant network protocols EIGRP and BGP and we also will focus on their configuration on the selected network devices. Routing in the network will be analyzed in the individual project scenarios with a use of selected routing protocols. Routing policy will be enforced for a BGP protocol in a separate scenario with an aim to prefer a concrete routing path to the destination, which is a common case of traffic engineering. The issue of virtual private networks is also taken into a consideration in an individual scenario, where there is Firewall as a specific network device used for separation of networks of a different trustworthiness and a following introduction of IP tunneling for an encrypted communication among the selected network entities within the topology. Simulation of the network communication is aimed on the response of FTP service, time delay of Ethernet, throughput of backbone links and communication flow in the targeted scenarios. The output of this work deals with the analysis of the achieved results, comparison of graphs as well as evaluation of the determined simulation parameters.

Analysis of wireless environment using the Ekahau system and the possibilities of cooperation with other systems
Tinka, Zdeněk ; Bartl, Milan (referee) ; Hošek, Jiří (advisor)
The work is divided into two parts. Firts of all deals with surveying and analysis of wireless environment. It contains familiar with analysator Ekahau Site Survey. Below are implementation of the map and then surveying of quality of networks. Finally describes the evaluation results and optimization of networks. The second part describes the localization of objects by AeroScout system using a wireless environment. It occurs in the theoretical description of the topology and equipment necessary for proper operation and practical work progress and evaluate the second part.

Service quality support in WLAN networks
Mizera, Josef ; Hošek, Jiří (referee) ; Novotný, Vít (advisor)
The bachelor´s thesis is focused on wireless networks WiFi and the transmission of multimedia using these networks. It discusses the connection of telecommunication and data networks, their common use for transfer of data in real time, particularly through wireless transmission medium using standards IEEE 802.11. It describes individual standards 802.11, mainly 802.11e on which is this bachelor´s thesis focused. The second part of the work is focused on designing the networks for measuring to verify the functionality of service quality support in the tested networks.

Universal platform for remote management of IoT devices and visualization of M2M data
Štůsek, Martin ; Hošek, Jiří (referee) ; Mašek, Pavel (advisor)
The aim of this diploma thesis is to create universal application able to visualize M2M data and allows remote management of smart sensors using TR-069 protocol. First part of this thesis contains comprehensive evaluation of TR-069 standard and OSGi platform. Next, extensive analysis of embedded databases with detailed description of SQLite platform is provided. Auto-configuration server genieacs and modus TR-069 client, two parts needed for the proper run of remote configuration, are described in more detail in following section. Practical part of this thesis contains description of all created OSGi bundles together with communication interfaces. Moreover, the description of designed database and developed user interface is given.

Design and implementation of 3D printer with network printing support
Špringer, Radek ; Hošek, Jiří (referee) ; Krajsa, Ondřej (advisor)
The goal of this thesis is to design a 3D printer type delta. To describe 3D printing technologies used by this printer, basic printer features and commercially available material used at the print and its comparison. To define all hardware components, which are necessary for construction of the 3D printer type delta. To create a proposal and construct an expansion board to which all hardware components of the printer will be connected. To optimize the print space heating and cooling of the printout. To extend the 3D printer with a Web server, which will ensure the network printing possibility.

Verification of MANET Routing Protocol potentials in OPNET Modeler environment
Konečný, Daniel ; Skořepa, Michal (referee) ; Hošek, Jiří (advisor)
This bachelor’s thesis called "Verification of MANET routing protocol potentials in OPNET modeler enviroment" is focused on MANET network. The first part is introducing routing protocols that are most used in OM. The second part of that work is strictly aimed to DSR routing protocol, its parametrs and configuration in OM. There is also discribed DSR process model. The most important part of that thesis is extension of data unit of DSR protocol and use that unit for transmision of information that are stored inside of its structure. As the extended unit was chosen Route Request packet that include new variable. The simulations are proving succesfull traffic of extension packet between nods with ability to store/read from RREQ extended structure.
