OS Google Chrome - theory and practice
Plecháč, David ; Halbich, Čestmír (advisor) ; Tomáš, Tomáš (referee)
The thesis is focused on the characteristics of the key features of the operating system Google Chrome OS and on the evaluation of deployment of this operating system in practise. The theoretical part describes the purpose and philosophy of the commercial operating system Google Chrome OS and its relation with Chrome web browser. The connection with open-source projects Chromium and Chromium OS is explained. Details of application development and deployment options, in the form of virtualization and domain administration, are analysed. The practical part applies theoretical knowledge from the development of applications for Chrome OS to create thin client application for remote control of hardware sensor over the internet. This sensor is designed and built on the platform Arduino. The sensor measures the temperature and humidity of the ambient air and remote controls high-voltage switching relays. Communication over TCP/IP uses modern MQTT protocol, for which the server is configured with MQTT Broker Mosquitto.
The next section demonstrates the procedure for building a customized build of Chromium OS from the publicly provided Google source codes. Based on the evaluation of the acquired theoretical and practical knowledge, I assess the possibility of deploying the Chrome OS in private and commercial areas.

Sensing Device based on Windows 10 IoT Core
Vaľuš, Dávid ; Zeman, Kryštof (referee) ; Hošek, Jiří (advisor)
This bachelor thesis focuses on installation of system Windows 10 IoT Core on microcomputer Raspberry Pi 2 and creating AllJoyn application for measuring temperature, humidity and brightness via bluetooth interface. In theoretics part technologies like M2M (Machine To Machine) and IoT (Internet of Things) are described, actuall trends and the future and AllJoyn platform. There is also a comparsion of operating systems available for Raspberry Pi 2. Practical part focuses on the installation of system Windows 10 IoT Core on Raspberry Pi 2 board. It also deals with verification of the functionality of the system via testing aplication for temperature measurement via SPI interface and bluetooth. In practical part we joined the AllJoyn network and via this network we shared data from a Bluetooth sensor.

Simulation of H2H and M2M Communications in Mobile Network LTE-Advanced
Číhal, Josef ; Mašek, Pavel (referee) ; Hošek, Jiří (advisor)
This bachelor thesis „Simulation of H2H and M2M communication in LTE-Advanced mobile network“ focuses on theoretical study of H2H (Human to Human) and M2M (Ma- chine to Machine) communication in fourth-generation of mobile network (LTE/LTE- Advanced). It also focus on the influence of M2M communication to compliance with the agreed terms of quality of service (QoS) for H2H traffic. Based on the theoretical analysis was created model of H2H and M2M communication using NS-3(Network Si- mulator 3). Last part of bachelor thesis deals with verification of the functionality of created model through simulations focusing on the key operational parameters such as delay, throughput and load of base station (eNodeB).

Performance Analysis of Mobile Networks for M2M Communication
Důbrava, Marek ; Kováč, Dominik (referee) ; Mašek, Pavel (advisor)
This bachelor thesis "The benchmark analysis of mobile network for M2M communication" focuses on theoretical study of M2M devices and third- and fourth-generation mobile networks. The second part of the thesis is devoted to the LTE network overload simulation. The LTE network overload is achieved in two ways: the overload caused by the volume of data transmitted, or the overload caused by devices newly connected to the network. The third part of the thesis deals with the design and simulation improvement of M2M communication in the LTE network. A network simulator OPNET Modeler was used for the simulation.

Verification of MTCG's Influence on eNodeB Utilization in Mobile Network LTE-Advanced
Bartal, Boris ; Mašek, Pavel (referee) ; Hošek, Jiří (advisor)
This thesis is dealing with the problem of MTC (Machine Type Communication) devices accessing LTE (Long Term Evolution) network. First part of work contains theoretical description of MTC, LTE network and possibility of using QoS (Quality of Service) for this type of communication. Influence of simultaneous access of large number of MTC devices into LTE network is examined. A solution is proposed -- usage of MTCG. In simulation enviroment NS-3 (Network Simulator 3), two scenarios are created for simulation with and without MTCG. The results of these simulations are then compared.
