Creating a simulation model of the access network
Formánek, Juraj ; Slavíček, Karel (referee) ; Grenar, David (advisor)
Thesis deals with generating and monitoring traffic in the GNS 3 simulation tool. The properties of the GNS 3 simulator are defined, including its capabilities for simulating/emulating components. Emphasis is placed on using only open-source tools. After analyzing the capabilities of GNS 3, a suitable traffic generator is found, which is preceded by practical testing of multiple generators. After finding the generator, monitoring tools are practically tested, with Zabbix emerging as the best from the tests. It was linked with the visualization tool Grafana through Zabbix plugin. Part of the work consists of automation, managed by Zabbix along with bash/Python scripts. The thesis evaluates the use of GNS 3 and explores its capabilities, possibilities, and limitations in the area of traffic monitoring and generation. The result is the creation of an access network with one router and two containers that generate and send traffic through this router. Everything is monitored by Zabbix and useful results are displayed in Grafana.

Effective management of building technologies with a focus on measuring humidity and CO2 concentration
Bučko, Ondrej ; Bátora, Branislav (referee) ; Janík, Daniel (advisor)
The diploma thesis deals with automated measurement of humidity and CO2 concentration inside buildings. Results of this measurement form the input parameters for the effective management of technologies reducing the energy performance of buildings. In the introduction, the issue of indoor air quality of buildings and indicators characterizing this quality are approached. The technical part of the thesis consists of making a measuring device which contains two prototype sensors provided by Teco Inc. with online access to measured data. The measurement of relative humidity, CO2 concentration and temperature in the interior of the building with the made device is compared with commercially available devices for measuring selected parameters. For unambiguous interpretation of online data, the virtual machine with an online database is configured for the created measuring device. The possibilities of using the prepared measuring device to achieve a reduction in the energy performance of buildings are discussed in the final part.

The Benefits and Pitfalls of Smart Meter Data Collection
Bazal, Stanislav ; Morávek, Jan (referee) ; Šedrlová, Magdalena (advisor)
In recent years, the demand for electricity has been increasing in households because various appliances and newest technologies have been used on an everyday basis. This raises concerns about the lack of electricity production around the globe. There is also a need for people to track their daily power usage in houses. The aim of this thesis is to explain the term smart metering and its benefits for both people that might use this technology in their households, and for companies. Smart meters allow people to track and control their energy consumption and eventually it might result in cheaper costs of the resources. What is more, the smart meters help consumers to know specific information about the consumption of electricity for appliances. In a global scale, the smart metering technology is used in smart grids which are more environmentally friendly power grids with higher efficiency and greater energy production. This work also focuses on the overall distribution of smart meters both in the Czech Republic and in the world. Nowadays, there are many projects in progress that are trying to switch from traditional power plants to smart grids with the intention to increase energy production and to become eco-friendly. The companies behind these projects have already published some of their researches which bring positive information about the energy production. The majority of these projects should be in progress until 2020 and some until 2025. Therefore, the final conclusion whether the smart metering technology will replace the traditional power grids and will be implemented in households cannot be drawn yet. This thesis also contains a practical part in which I create a user interface in Grafana, which is an open-source software for time series analytics. The user interface is created for a Raspberry Pi touch display which has a sensor connected to it that allows us to measure energy consumption of electricity meters. The measured values are then presented in useful graphs and gauges in Grafana, and also on the display itself.
