Testing communication protocols using mobile technologies for the Internet of Things LTE-M and NB-IoT
Bartko, Samuel ; Dvořák, Radim (referee) ; Možný, Radek (advisor)
This thesis focuses on a comprehensive investigation and evaluation of the currently widespread communication protocols in the dynamically developing IoT sector (Internet of Things). With the proliferation of IoT, there is a need to create new technologies for efficient interconnection of hysical and digital worlds. The main objective of this work is to test and evaluate the suitability of use and optimal configuration of communication protocols in the context of the latest implementations of mobile technologies for IoT, namely LTE-M (Long-Term Evolution Machine Type Communication) and NB-IoT (Narrowband Internet of Things). This thesis investigates and evaluates the current communication protocols for the Internet of Things (IoT), focusing on LTE-M and NB-IoT. It includes a theoretical perspective on IoT, description of mobile technologies and analysis of protocols such as MQTT, CoAP and LwM2M. A practical part is devoted to testing and optimization of these protocols. The result of the work is providing\break a comprehensive overview and practical recommendations for use and configuration communication protocols in the framework of NB-IoT and LTE-M technologies.

Ensuring availability and security in industrial networks
Zatloukal, Zdeněk ; Fujdiak, Radek (referee) ; Holasová, Eva (advisor)
Currently, a key aspect of industrial automation is ensuring a high level of security, reliability, and data availability in industrial communication networks. Given the rising cyber threats, it is essential to develop and implement advanced strategies for protecting industrial infrastructures. This thesis aims to perform a comprehensive analysis and development of security solutions for industrial networks, focusing on the Modbus RTU/TCP and MQTT communication protocols, which are crucial for the effective management of modern industrial operations. The work employs methodological approaches that combine theoretical research with practical experiments. It includes an analysis of existing protocols, the design of communication security through these protocols, and their subsequent testing in a controlled industrial environment to verify security, efficiency, and reliability. The analysis revealed significant deficiencies in the security of existing systems and led to the integration of new security measures into the industrial switchgear, which significantly improved the protection of data and communication infrastructure. The implemented solutions demonstrate significant progress in protecting industrial networks against various types of attacks. This thesis represents a significant contribution to the field of industrial network security. The results of the work provide valuable information for the further development of security technologies in the industry and offer practical guides for engineers and technicians who are working on improving the security status of industrial systems.

Implementation of Communication Technology complying IEC 61850 as the Demonstrational DCS System
Kozák, Ondřej ; Arm, Jakub (referee) ; Fiedler, Petr (advisor)
This thesis deals with the issue of communication of protection by IEC 61850 standard and reading, control and visualization of protections by DCS systém 800xA and PLC AC500 from ABB and extended visualization by cloud service Grafana. The IEC 61850 standard, its protocols anad the topologies used have been descibed in this work. Furthermore, the basic functions of the instruments used were described. The main part describes the procedure of creating SCD file for communication configuration and subsequent uploading to individual systems, creating visualization in DCS 800xA system, setting up communication between protection devices and reading from them using AC 500 PLC. For the cloud service there is a description of the implementation of the MQTT broker for sending data between PLC and database Influxdb that stores the data and forwards it to Grafana visualization environment.

Linux distribution for smart building gateway
Nagy, Tomáš ; Komosný, Dan (referee) ; Jablončík, Lukáš (advisor)
The goal of the thesis was to create a Linux distribution for a smart home gateway. The thesis is divided into theoretical and practical parts. The theoretical part dealt with the analysis of the Linux operating system. Subsequently, single board computers are described and compared. In the next part, the gateway issues, communication protocol selection and application containerization are discussed. As a result of addressing the issue, a procedure for adding tools for home automation, the construction of scripts that automate this issue and instructions for their proper execution were proposed.

Intelligent Access Terminal Using ESP32 Platform
Pomykal, Šimon ; Vašíček, Zdeněk (referee) ; Šimek, Václav (advisor)
The aim of this thesis is to design cheap intelligent access control system based on esp32. This system is designed for use in family houses, flats, garages, gardens etc. The designed system is composed of access control terminal module which uses fingerprint reader to authenticate people and of camera modules which monitor the area of entry These modules are connected to cloud using AWS IoT Core. Another part of the system is a cloud application which evaluates data from the system. The acces control system is meant to be part of a home security system, but can be used independently to some extent.

Telemetry Data Collection and Evaluation
Spurný, Jan ; Krajsa, Ondřej (referee) ; Číka, Petr (advisor)
This thesis describes design and creation of application which collects and values telemetry data. Thesis consist of design and implementation which describes whole system, server settings as well as approach how to consume any given data. Corner stone of this application is based on given data from telemetry station (sensors) and projecting them on the map background. Application consist of user interface and logic how to project any given data into the map. Graphics interface is created using HTML, JavaScript and CSS programming languages. Logic itself is programmed by using backend language PHP including Laravel Framework in combination with MySQL database. Result of this thesis is working implementation covering administration user interface, working cooperation of MQTT server and APIs. There are also implemented all necessary parts for enablement of user interface with cooperation with map background layer. Implementation creates two possible ways how to install package necessary to run this app on Ubuntu system.
