New Family House Computer Network Design
Hruška, David ; Košťál, Lubor (referee) ; Ondrák, Viktor (advisor)
The bachelor´s thesis conurned with the design of computer network in a new family house. This work presents the theoretical basis for understanding of the problems and consequently the design of the network itself. At the base of the specific requirements of homeowners are selected devices and their overall calculations.

Design of Computer Network for Small Company
Vaňková, Jana ; Jordán, Vilém (referee) ; Ondrák, Viktor (advisor)
I have chosen the topic "Design of computer network for small company" for the elaborating of my thesis. I will deal with analyzing of the current quality of computer network company in IP IZOLACE POLNÁ, s.r.o., describing of the theoretical way-outs and last but not least, own suggested solutions in this work. Today (present) computer network is not sufficient, especially due to expansion of the company and therefore its recovery is important. Relevant standards must be complied and also the budget that the company is willing to invest must be kept during elaboration of my work.

The Project of Computer Network for Elementary School
Němec, Ondřej ; Černý, Stanislav (referee) ; Ondrák, Viktor (advisor)
I chose computer science institute to work out the bachelor thesis. The specific topic of my thesis is "The project of computer network for elementary school. The kontent of this work is to analyze the current state of the computer network at elementary school in Třešť then describe the theoretical background for my thesis, and on these thesis handle a possible solution. This is mainly to find weaknesses in the computer network and a proposed new network these deficiencies. Of course it is essential that everything was handled according to relevant standards. It is important to find the correct boundary between the financial possibilities of elementary schools and their needs.

Model for power line communication
Baluch, Viliam ; Fujdiak, Radek (referee) ; Mlýnek, Petr (advisor)
This bachelor thesis is dealing with matters of data communication after power line. The thesis is including the PLC systems history, current possibilities of utilization and different types of modulations being used, interference sources and parameters of a transmission line. We will elaborate on methods of transmission line modeling and one of them will be used in the practical part of the thesis. The practical part consists of modeling of different types of topology and impedance endings applying generation of random transmission parameters and sizes of typology. We analyze results from practical measurement which are incorporated in a model. The model is then being compared with another one in terms of fixed parameters.

Discovery of Wireless Sensor Network Topology Using Genetic Algorithms
Dalecký, Štěpán ; Samek, Jan (referee) ; Zbořil, František (advisor)
The thesis deals with a design of the genetic algorithm that is able to discover the wireless sensor network topology using signal strength among particular sensors. At first, the thesis describes the theory of genetic algorithm and wireless sensor network. Subsequently, on the basis of this theory, the genetic algorithm serving for the wireless sensor network topology discovery has been designed. The thesis also describes important features of the algorithm implementation. In conclusion, the outcomes have been reviewed.

Acquisition of communication statistical data from network infrastructure devices
Gargulák, Lukáš ; Nagy, Ľuboš (referee) ; Krkoš, Radko (advisor)
The diploma thesis describes theory that is needed for application development for acquisition of communication statistical data from network infrastructure devices. Aplication is called SDSKSI. The project compares protocols suitable for this purpose. Finally SNMP protocol was chosen because it is the most common in network devices. SNMP is described in detail. Each SNMP operation has its own practical demonstration. In the project there is also described MIB database and data types of MIB objects. Application is able to create network topology. Then administrator of network can imagine how the network looks like. For each device that support SNMP protocol are periodically collected and stored statistical data which can be exported to the file. For application development were chosen programming languages according to several criteria. Content of the laboratory exercise is presented. At the end of the project there are some system solutions for collecting statistical data. Diploma thesis contents two attachments. The first is containing the full text of laboratory task. The second is DVD disc. Disc is containing ready to boot aplication SDSKSI.

Wireless communication modules for microcontrollers
Klíma, Jan ; Matěj, Zdeněk (referee) ; Fedra, Zbyněk (advisor)
The aim of this master’s thesis is analysis of wireless communication between mikroprocesors. The first part of the work are analysed the problems the wireless free ISM band. Mainly RFM12B and ZigBee module, which i these band work and ZigBee standart. The second part are described relazation board for both module. Further how programming ZigBee module. And at last programs for tested module.

Automatic topology recognition and network monitoring based on FreeBSD
MACEK, Petr
The goal of the Bachelor Thesis is the creation of system tool for topology recognition and following LAN monitoring. This tool will be built on OS FreeBSD and formed like bootable image suitable for running from the USB stick. Besides the lower layers protocols TCP/IP, the protocol SNMP will be used for topology recognition and network monitoring. The tool will monitor state, network transmissions and other values at active network components too. Communication with the user will be realized via www interface. The goal is to create the tool executable on any computer without installation, to perform quick topology recognition, its visualisation and basic monitoring. It is supposed to be the opposite of the tools of NMS type that need installation on server, database server and have other requirements.
