Mobile Application for Remote Measurement Support Using Sigfox Communication Network
Bulawa, David ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
The purpose of this project is the implementation of a mobile application for the operation system Android. The application supports remote metering via the Sigfox network and local metering via Bluetooth Low Energy. I implemented it natively in the Kotlin programming language using the Model-View-ViewModel design pattern. Measured values are collected remotely using the Sigfox REST API and locally using the Android Bluetooth library. The collected data are persisted in the local database on the mobile device. Then, the data is interpreted and visualized into graphs that the user can customize. The created solution provides a possibility to acquire, monitor and visualize data from sensors, including their historical values. The application is easy to use, but also allows configuring data interpretation and supports several different incoming message formats.

Design of communication interface in WBAN systems
Kandera, Tomáš ; Najman, Jan (referee) ; Krejsa, Jiří (advisor)
Táto diplomová práca sa zaoberá technickou realizáciou WBAN zariadenia, ktoré je schopné súbežne komunikovať prostredníctvom dvoch bezdrôtových komunikačných protokolov. Rešerš dostupných riešení je dostupná s hodnotením jednotlivých produktov podľa vopred stanovených kritérií. Návrh z hľadiska software obsahuje tvorbu vlastného BLE servisu, konfiguráciu Timeslot API a periférií často využívaných vo WBAN zariadeniach. Výroba dosiek plošných spojov pre zariadenie a dedikovaný ovládač zahŕňa vlastnú anténu, nabíjací obvod batérie a nRF52810 čip. Testovanie prototypov je zhrnuté v poslednej kapitole spoločne s experimentálnym meraním útlmu živočíšneho tkaniva.

Anomaly Detection in IoT Networks
Halaj, Jozef ; Hujňák, Ondřej (referee) ; Kořenek, Jan (advisor)
The goal of the thesis was an analysis of IoT communication protocols, their vulnerabilities and the creation of a suitable anomaly detector. It must be possible to run the detector on routers with the OpenWRT system. To create the final solution, it was necessary to analyze the communication protocols BLE and Z-Wave with a focus on their security and vulnerabilities. Furthermore, it was necessary to analyze the possibilities of anomaly detection, design and implement the detection system. The result is a modular detection system based on the NEMEA framework. The detection system is able to detect re-pairing of BLE devices representing a potential pairing attack. The system allows interception of Z-Wave communication using SDR, detection of Z-Wave network scanning and several attacks on network routing. The system extends the existing detector over IoT statistical data with more detailed statistics with a broader view of the network. The original solution had only Z-Wave statistics with a limited view of the network obtained from the Z-Wave controller. The modular solution of the system provides deployment flexibility and easy system scalability. The functionality of the solution was verified by experiments and a set of automated tests. The system was also successfully tested on a router with OpenWRT and in the real world enviroment. The results of the thesis were used within the SIoT project.

Integration of New Wireless Technologies and Devices into the BeeeOn Gateway
Bednařík, David ; Korček, Pavol (referee) ; Kořenek, Jan (advisor)
This master thesis deals with the integration of new devices from the manufacturers Revogi, Tabu Lumen, Sonoff and HomeMatic into the BeeeOn Gateway software. The theoretical part deals with the architecture of the BeeeOn Gateway software and describes the characteristics, behavior and way of communication with devices from the above mentioned manufacturers. This part of thesis also contains a description of the communication technologies used by these devices. They include Bluetooth Low Energy, the WiFi and the 868 MHz radio. The practical part mentions the way of extension of BeeeOn Gateway software to modules that implement support for smart devices. This section also describes how the correctness of implementation was verified and testing of the entire BeeeOn Gateway software. The testing of gateway is performed by unit and integration tests, which verify the behavior of individual gateway components as well as the whole gateway.

Construction of a Pen with Hidden Acquisition of Behavioral Signature Samples
Müller, Dominik ; Sakin, Martin (referee) ; Drahanský, Martin (advisor)
This thesis deals with the construction of pen for hidden acquisition of behavioral signature samples. The proposed system provides realtime data acquisition with recording possibility. Signature samples are acquired using inertial sensors and pressure sensor. The custom printed circuit board with pen model have been developed. The special application has been developed for pen control. Received data are further processed for pen movement recognition. Bluetooth Low Energy has been used for communication and data transfer.
