IoT Control Module
Haman, Martin ; Marcoň, Petr (referee) ; Szabó, Zoltán (advisor)
This bachelor thesis deals with the research of the possibilities of wireless data transmission from the controllers IoT modules and their construction. At first there is compared wireless technologies, network protocols, their suitability depending on the application of the IoT control module. Then it is designed the IoT control module using a Wi-Fi module (based on Espressif ESP8266 integrated circuit) communicating over a MQTT network protocol. Thesis continue with selection, compilation of the firmware, creation of script for control heating system, descriptions of methods for controlling the IoT control module and display of measured data. The possibilities of creating a MQTT broker and security of data transmission are described below. In conclusion is documented and verified its functionality.

Wireless Control of Electronic Devices Using Mobile/Embedded Device Using WiFi
Marek, Petr ; Materna, Zdeněk (referee) ; Zemčík, Pavel (advisor)
The aim of this bachelor thesis was to design and implement an automated home system using Wi-Fi. The whole system was built on the Raspberry Pi and ESP8266 platforms, CoAP was chosen as the communication protocol. The resulting solution works in the local network and also over the Internet. It includes the use of several types of sensors and the ability to control the outputs of the ESP8266 modules. The system supports simple automation based on values of sensors and set timers.

Laboratory Demonstrator for LPWA Technologies Enabling the Communication via the Lightweight M2M (LWM2M) Protocol
Dvořák, Radim ; Štůsek, Martin (referee) ; Mašek, Pavel (advisor)
As the number of wireless devices rises, so does the demand for reliable data transmission. To ensure the reliability of data transfers with such devices, suitable wireless technology, and a suitable transmission protocol have to be chosen according to the device capabilities and requirements. This thesis describes LPWA (Low-Power Wide-Area) technologies currently available on the market, both on licensed spectrum and non-licensed spectrum, focusing on licensed spectrum technologies (Narrowband Internet of Things, LTE-M) and also commonly used M2M enabled protocols for IoT devices. Furthermore, it compares those protocols from the communication parameters and data traffic perspectives with focus on overheads that further increase the amount of data transmitted but are necessary to ensure reliable data transmission. Lastly, it focuses on LWM2M protocol describing it to the detail and describes an LWM2M C++ library created as part of this thesis. In addition, a laboratory demonstrator was created utilizing this library.

Secure Communication and Data Protection in the Internet of Things
Chadim, Pavel ; Hajný, Jan (referee) ; Malina, Lukáš (advisor)
This Master's thesis „Secure communication and data protection in the internet of things“ is dealing with crypthografy and crypthographic libraries, which are compared with eachother according to supporting algorithm and standard. For comparing therewere used following libraries: openSSL, wolfSSL, nanoSSL and matrixSSL. Practical part of the thesis is focused on testing the productivity of each ciphers and protocols of openSSL and wolfSSL libraries on RaspberryPi 2 device. Further, the thesis shows the design of communication scenario client-server in the Internet of Things (IoT). Simple authentication protocol client-server was implemented and simulated on RaspberryPi 2 device.

Internet of Things
Piškula, David ; Nosko, Svetozár (referee) ; Musil, Petr (advisor)
This thesis focuses on the Internet of Things and some of the most important problems it faces today. Among these are the overdependence on the Cloud and lack of autonomy, poor security and privacy, complicated initialization and power consumption. The work aims to implement a complex IoT solution that solves the discussed problems. The project is part of a collaboration with NXP Semicondutors and will be used to showcase the company's technologies.

Internet of Things Device Based on ZigBee and 6LoWPAN
Halász, Dávid ; Mlích, Jozef (referee) ; Musil, Petr (advisor)
Internet of Things is the latest phenomenon in the computing industry. Even if it has not been completely defined yet, we are already surrounded by various devices connected to the Internet. This thesis project focuses on low cost and low-power wireless solutions and on the on-line backend behind the architecture. At the same time the present work also deals with Cloud Computing which can provide a highly scalable runtime environment for this backend without building an infrastructure. To handle the huge amount of data collected by billions of devices, BigData services could be used in the same cloud space. The project is a collection of the theoretical background of the Internet of Things; so as a result, it provides the reader with an overview of the concept. It also provides a walktrough of the design, implementation and testing process of a complex agricultural Internet of Things solution.

Smart Forest: Utilization of 5G Networks for Fire Detection and Prediction
Popelka, Adam ; Možný, Radek (referee) ; Mašek, Pavel (advisor)
The goal of bachelor thesis was in teoretical part study and describe Internet of Things, found difference between H2H (Human to Human), M2M (Machine to Machine) and mMTC (Massive Machine Type Communication), describe LPWAN (Low Power Wide Area Network) in licensed and unlicensed frequency band and compare them. The next task was describe in detail technology in licensed frequency band NB-IoT and LTE Cat-M and choose ona of the technology for use in practical part. In teoretical part it should also be found description of application protocols for LWPAN as MQTT, CoAP, LWM2M and then describe security. The task in the practical part was to choose a communication technology, communication module and device that will be used to measure the temperature, take photos of the surrounding environment, and then send the obtained data to the server. In order to put the device into operation, a program must be created that will measure the ambient temperature at intervals, which it will evaluate and, in the event of and excess, take a picture of the environmet and send the data to the server.
