Smart Home Control
Fučík, Jan ; Beran, Vítězslav (referee) ; Zemčík, Pavel (advisor)
This thesis summarizes the subject of intelligent homes and describes commonly used standards and commercial solutions on the market. The thesis covers the design of a low-cost and easy to use smart home system which can be managed over the internet, uses a genetic algorithm for heating regulation optimization and its central computing unit is a low-cost, embedded device with low power consumption. The functionality of the system is verified on a practical application of heating regulation in a house. The efficacy of the system for energy savings is shown; it is based on measured data statistics.

UDP a TCP Communication for FITkit
Musil, Martin ; Strnadel, Josef (referee) ; Vašíček, Zdeněk (advisor)
The aim of this thesis was to extend educational platform FITkit for the possibility of communication via TCP and UDP protocol. Communication is provided by Ethernet module ENC28J60 from Microchip. Communication protocols are provided by library enc28j60, which is implemented in C language. The theoretical part deals with analysis of network protocols to be implemented. Work continues describing the characteristics and parameters of the connected module. Followed by a design library in which is particular emphasis on limited computing resource of the platform. In the implementation of the work is to describe the application interface and the basic principles of the library.

Model of computer network in MATLAB/SIMULINK environment
Zedníček, Petr ; Zeman, Václav (referee) ; Kolka, Zdeněk (advisor)
The bachelor thesis deals with simulation of TCP protocol behaviour in Wireless optical environment. The thesis examines the various parameters of the protocol and evaluates their response to the transmission speed. The key objectives of the thesis are the introduction to the problems of communication, specially the description of the transport layer architecture, TCP / IP and congestion management mechanism NewReno. A large part of the thesis is devoted to modelling communication points and a model of optical wireless connections. The results will be applicable to create a new communication protocol for Wireless optical environment.

HW and SW for Ethernet-to-IEEE802.15.4 bridge
Růžička, Tomáš ; Štohl, Radek (referee) ; Fiedler, Petr (advisor)
In this work we deal with the converter, to serve as a bridge between the two protocols. These protocols are Ethernet and wireless IEEE 802.15.4 protocol. Wireless part of this work, however, I simulated via serial RS 232nd After Ehternetu can send data via TCP or UPD protocol. First is the need for a converter to connect to the network and then create a packet. Finally, it is necessary to also address the views received and sent data via Ethernet and the RS-232.

Simulator and client for MODBUS devices
Ondrášek, Michael ; Franek, Lešek (referee) ; Fiedler, Petr (advisor)
This bachelor’s thesis deals with communication protocol MODBUS. The properties of the protocol and its function are described at the beginning of a thesis. There are designed two applications on the basis of identified properties in the other part of thesis, they represent the server part and the client´s part. The server part is implemented by selected functions of protocol and it represents devices for data collection. The next part is the detailed design of applications and the description of their realization. The last part deals with testing of designed applications with available SW simulators. The thesis deals also with user manual for control of created applications.

Laboratory of Quality of Service
Eltahir Ahmadon, Ahmed ; Kolka, Zdeněk (referee) ; Polívka, Michal (advisor)
The Bachelor's work, you are reading, deals with the issue of VoIP calling and measurement its quality. In the following paragraphs the discussion will be about the basics of networking protocols such as TCP, UPD, IP and SIP, after that a preliminary introduction to QoS issues - ways of measuring voice quality for instance MOS and E-Model. Importance of implementing QoS for VoIP, and QoS parameters used in the proposed services (will be called "mechanisms"), such as Best effort service, Integrated and Differentiated services. Based on these fundamentals points with designed laboratory for quality of service. The laboratory will be aimed at testing the quality of codecs with regard to bandwidth, jitter, delay and packet loss. The solution lies in the fact that, which codecs are actually suitable for the service.

Laboratory exercises for network technologies education
Kapusta, Martin ; Langhammer, Lukáš (referee) ; Dvořák, Jan (advisor)
The aim of the diploma thesis is to choose network simulator suitable for network technologies laboratory tasks for educational use. Theoretical part of thesis describes basics of network communication, addressing, reference models. Thesis also describes standards Wi Fi, Ethernet and routing protocol OSPF - technologies which are discussed in laboratory tasks. The practical part of diploma thesis describes a few available network simulators suitable for creating two laboratory tasks. Finally, the NS-3 simulator was chosen. Both laboratory tasks include theoretical introduction, detailed description of source code, individual tasks, expected outputs and control questions which senses understanding of discussed technologies.

Laboratory stand with RABBIT CPU
Váša, Tomáš ; Štohl, Radek (referee) ; Bradáč, Zdeněk (advisor)
This master’s thesis contains design of laboratory stand for learning programming microcontrollers. Stand is equipped with two Rabbit modules, which are connected together over local area network. Exercises are focused on working with basic peripheries as digital inputs and outputs,PWM modulation, serial communication. Exercises are interested in evaluation of matrix keyboard and communication with alphanumeric display controller. With the ability to easy access the Internet some exercises are designed for work with this interface. To these exercises is made a preparation of external peripherals. Through these peripherals there can be can be controlled DC motors, step motor, binary outputs and inputs. Each lab exercise contains an introduction, task, instructions and the flowchart of realized exercise. Instructions are written so that it contains important steps to properly manage assignments. Individual exercises are designed to gradually increasing complexity of exercises.
