Quality of services support in the end applications
Zelinka, Jiří ; Novotný, Vít (referee) ; Hošek, Jiří (advisor)
The topic of this diploma thesis has been chosen for a discussion and implementation of quality of service on the application and link layer of the OSI model. At the beginning of this thesis the general parameters and basic technologies of the OSI model network layer has been explained. This part was chosen as a resource for explanation of the basic parameters in the quality of services. Basic part is followed by the introduction to the Ethernet technology, which became as a ground for the real model in this diploma thesis. As a part of this section has been written a block which contains a analysis of quality of services in the Ethernet, which means the implementation of IEEE 802.1Q/p. This analysis is followed by structured descrition of the controlling and functionality of quality of services parameters on the link layer with the system tool in the Windows XP, description of Win XP link layer drivers and its modification with system tool tcmon. The end of the theoretical part is represented by introduction to the implementation of quality of service in the wireless networks especially the 802.11e standard. At the beginning of the practical part is specified the description of the topology design which is dedicated to the quality of services implementation. This section is developed to well-founded analysis of applications which were used during topology creating. The last segment of this thesis is dedicated to evolving the practical informations which were obtained during the measurement.

Two Legged Walking Robot
Kraus, V.
The aim of this work is to construct a two-legged wirelessly controlled walking robot. This paper describes the construction of the robot, its control electronics, and the solution of the wireless control. The article also includes a description of the application to control the robot. The control electronics of the walking robot are built using the development kit Arduino Mega, which is enhanced with WiFi module allowing the wireless control, a set of ultrasonic sensors for detecting obstacles in the robot`s surroundings and accelerometer for maintaining balance.

Building and using of a small computer networks
Chuchmák, Miroslav ; Pinkas, Otakar (advisor) ; Šmejkal, Ivo (referee)
This Bachelor Thesis deals with designing and building home network according to user requirements. A major aim of this thesis is to describe how to proceed, when creating a draft of home network extension. It is explained how the network can be expanded by other network elements, so that, it allows users to access the Internet and data store from home network and beyond.The Bachelor Thesis is divided into four segments. The first segment assesses the current condition of the home network, in the second segment, the new solution is suggested. The third segment describes the realization of a home network, including the configuration of a new device. The last part evaluates the new state, including the cost of implementation.

Building and using smaller computer networks
Ďurica, Matej ; Pinkas, Otakar (advisor) ; Šmejkal, Ivo (referee)
In these days, the widespread creation of home networks, due to the continuous development of computer technology for personal use. These networks are formed, for example, with the aim of facilitating access to information, ease of communication between people and control of various devices in the home. Their development is influenced by trends in information communication technologies in the market. This bachelor thesis is fully focused on the practical implementation of the proposal for extension of the original smaller home network using the new network elements (wireless routers, switches, network printers, NAS server, device for live monitoring of security cameras) and rendering certain network services (DLNA, print server, VPN, iTunes server, live monitoring of security cameras). A given network was tested with respect to performance network and its response, coverage of Wi-Fi signal, testing remote access, power consumption, read and writes speed of the NAS server.

Building and use of small computer networks
Nepomucký, Pavel ; Pinkas, Otakar (advisor) ; Šmejkal, Ivo (referee)
The thesis deals with design of small home network. The main goal is to describe extending home network by new network components, which allow users in specific areas to use newly created wireless connection. The thesis is split into two parts. The first one is given for explanation of network components and their comunication. Second one describes practical demonstration of extending home network by a new component providing wireless conection. The thesis decribes a selection and analysis of network components including setting up, coverage and communication between each access point.

Design and security of small wireless network
Cikánek, Svatopluk ; Pinkas, Otakar (advisor) ; Šmejkal, Ivo (referee)
This thesis deals with design and security of small wireless network and providing selected network services. The thesis is divided into four main parts. The first part is dedicated to theory of networks and looks into metallic and wireless networks and functions of some network components. The second part describes current network in dwelling-house and its network components. The third part deals with network design, innovation, choosing of components and their settings. The last part is devoted to providing network services, their settings and attest.

Building and use of small computer networks
Pecka, Jiří ; Pinkas, Otakar (advisor) ; Palovský, Radomír (referee)
The thesis deals with a new design for the home network according to the given requirements of its users. The main aim is to describe how the network can be expanded to include other elements to allow users to access the Internet, data storage and other services via wireless networks in selected locations. The thesis it divided into three parts. The first part describes the previous state of the network and users' requirements for improvements. The second part describes the network and device settings. The third part is devoted to the network testing, including evaluation of the signal strength of access points in all areas of the selected sites and attack simulation on the access point.

Building and use of small computer networks
Zitta, Vladimír ; Pinkas, Otakar (advisor) ; Šmejkal, Ivo (referee)
Bachelor thesis deals with the design, construction and testing of a home computer network. The first part is theoretical and is devoted to network elements, protocols and standards that will occur in the home network. The second part is practical and deals with the main aim of the text, designing extended home network and it's implementation. Described are selected network elements, configuration, network services and subsequent testing of the network.
