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.

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.

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.
