Location of hosts in IPTV system
Pokludová, Michaela ; Burget, Radim (referee) ; Müller, Jakub (advisor)
This thesis deals with locating station in the digital television broadcast over the Internet Protocol. The aim of this thesis was to develop a general model for the location of stations in the system of internet TV. This work deals with the five known methods for locating stations in distributed systems, which compares as many criteria, such as coordinates of computation speed, accuracy of results. Based on the evaluation was selected optimal method, which has been incorporated into the simulation program IPTV and tested. The result of this work is the source code of the implemented methods.

Localization of nodes in Internet using Vivaldi system with adaptive time step
Mašín, Jan ; Balej, Jiří (referee) ; Komosný, Dan (advisor)
The aim of this thesis was to identification with the principles of logical evaluation of the position of stations on the Internet. Read up on the localization algorithm called Vivaldi with adaptive time step and subsequently to its implementation in the operating system GNU/Linux CentOS distribution. Do one's homework the PlanetLab experimental network (http://www.planet-lab.org/). At selected stations from the network transfer created by the application and verify its function on the real servers located at various places around the globe and assess the accuracy achieved by estimating the distance between stations on the PlanetLab network. In this scope of activity, the application was created to measure the delay prediction using Vivaldi algorithm with adaptive time step which is on principle of operation a client-server where the client performs the steps of the algorithm, Vivaldi and the server only listens, collects the resulting data Vivaldi algorithm and stores them neatly file. Furthermore, the application was developed for direct measurement of the delay, which also functions as a client-server. These applications have been transferred to the selected nodes from the PlanetLab experimental network. Subsequently, these nodes were running, to carry out the necessary measurements. The resulting values were work into tables of using Microsoft Excel. These values were then compared with direct measurements and competitive positioning by the King. Vivaldi localization methods with adaptive time step and the King, were compared based on calculated estimates of both real estate errors and measurement using distribution function of the relative errors of both methods. All this information was evaluated to compare accuracy of both the localization methods and direct measurements.
