Monitoring of System Resources Using OpenHAB Environment
Štůsek, Martin ; Kováč, Dominik (referee) ; Mašek, Pavel (advisor)
The aim this bachelor thesis is detailed familiarity with the technology OpenHAB and create functional application that displays resource usage. Monitoring of system resources won‘t be implemented only in one station, but in all instances OpenHAB in a local network. Created application also allows remote access to reference statistics, without having to connect to the same network. For obtaining system information is used system information package, which is built over SIGAR library. To transfer between stations and end-collection device is used HTTP binding and REST API. The first part of the bachelor thesis describes in detail the technology OpenHAB, the second part describes the technology used and the created applications. In the last section gives guidance on commissioning of OpenHAB on the end device.

Measurement of data network quality parameters
Ripper, David ; Kováč, Dominik (referee) ; Zeman, Václav (advisor)
The aim of this thesis was studying and describing known methods for testing transmission parameters in data networks based on protocol stack TCP/IP. Firstly were individual transmission parameters specified and determined their impact on service quality. Another aim was to carry out a comparison of the different methodologies of measurement of transmission parameters, performed their qualifications on the basis of these findings and methodology for measuring service quality from the user's perspective was proposed. It was a web application where users measured basic transmission parameters, then the users judged videos according to the evaluation scale MOS (Mean Opinion Score) and with the help of these data was analysis, classification connection and impact of connection on MOS evaluation.

Automated accounting system of phone calls
Kondler, Radim ; Kováč, Dominik (referee) ; Číka, Petr (advisor)
The thesis deals with the numbering plan, PBX, tariffs, draft disable tariff system and its possible extensions. Within numbering plans work deals with shapes of national and international figures, describes different types of these numbers, description of the structure and definition of fields, including the length of these fields. Within countries and regions of the Czech Republic are given individual prefix for both fixed and mobile networks. There are mentioned special shapes that are different in length compared to standard types. All these types of shapes are listed according to ITU-T. Within the exchanges are given generation switches, PBXs use within the telephone network and a description of the selected functions. Furthermore, there are kinds of pricing and options of valuation call. The work contains a description of automated acconting system, according to the principle of work of the program and a description of the individual steps and functions that thanks to the cooperation process individually each calls, convert numbers to international form, assigns the call tariff and appreciate the call according to the tariff. Finally, there are described possible extensions of this automated acconting system.

Functionality verification of GRP routing protocol in OPNET Modeler environment
Kováč, Dominik ; Růčka, Lukáš (referee) ; Molnár, Karol (advisor)
The bachelor's thesis "Functionality verification of the routing protocol GPR in the OPNET Modeler environment" focuses on MANET networks question and deals with routing processes in these networks. This thesis includes a theoretical analysis of the GRP routing protocol. Furthermore, there is a step-by-step creation of a MANET simulation model with GPR routing protocol in OPNET Modeler and its subsequent simulations to verify the functionality of the Protocol itself, its parameters and the extension of the hello paket by custom parameter.

Design of Mobility Model for Nano-Devices in NS-3 Simulation Environment
Miklica, Jan ; Kováč, Dominik (referee) ; Hošek, Jiří (advisor)
This thesis focuses on the description of nanocommunication networks, models for wireless communication networks and the description of motion in nanocommunication networks. The practical part describes the settings of the simulation scenarios for the definition of Brownian motion. Description is made for the simulation software NS-3 and N3Sim. In this thesis, the measured results of the simulations are summarized in tables and graphs. From the measured results the regression analysis is prepared. General summary of the results is provided at the end of thise thesis.

Implementation of Communication Protocol Wireless M-BUS in Simulation Environment NS-3
Zeman, Kryštof ; Kováč, Dominik (referee) ; Mašek, Pavel (advisor)
The theoretical part of the thesis focuses on history and development of M2M com- munication, Wireless M-Bus protocol and NS-3 Network Simulator. It briefly describes characteristics of M2M communication, Wireless M-Bus and NS3 simulator. Physical and link layer of Wireless M-bus protocol are described in great detail to provide basics needed for understanding and orientation in the topic. Practical part of the thesis is focused on structure of used Simple Wireless module and basic simulation scenerio is built. The scenerio demostrates basic functions of the module.

XML Data Compression
Jelen, Michal ; Polák, Josef (referee) ; Kováč, Dominik (advisor)
This master’s thesis is dealing with problems of XML data compression. It describes a characterization and important concepts of XML language as well as AIXM as XML data format. It documents contemporary compression methods of XML and divides them into appropriate groups. Thereinafter a testing of XML data compression using mentioned methods and evaluation of results is implemented. With a consideration of processed data there is created and presented an application which enables lossy and lossless compression of AIXM with the help of particular elements data analysis. All of it with user selection options of AIXM objects and way of resultant compression.
