Node localization on the Internet using artificial coordinate systems
Škvor, Martin ; Molnár, Karol (referee) ; Komosný, Dan (advisor)
This thesis is focused on methods for nodes localization in Internet using latency prediction in synthetic coordinates systems. Thesis also deal with methods, which latency prediction between nodes is based on other systems. Among such a methods particularly belongs King, which uses DNS (domain name service). Furthermore, thesis deal with relevance of overlay networks in latency prediction and their use for different services. Practical part of this thesis concentrates on method for latency prediction in synthetic coordinate system Global Network positioning. There were made two programs for counting coordinates of landmarks and hosts in this system. Measurements and calculations made in this thesis, are focused to determine accuracy of latency prediction of this method and their evaluation is made at the end of thesis.

Localization of nodes in Internet using Lighthouses system
Smrčka, Lukáš ; Müller, Jakub (referee) ; Komosný, Dan (advisor)
The thesis is focused on the localization of stations in the Internet with the help of artificial coordinate systems. These systems can be used to estimate the delay value of RTT between individual stations. The estimated delay value can e.g. help the station to choose an optimal second station for communication between two stations without the necessity to measure these values, which reduces the load of the net. The first part of the thesis describes systems that predict the delay and explains how the methods Vivaldi, Kings, GNP and Lighthouses work. The next part of the work gives basic information about environment where the chosen method shall be implemented. The final part defines both the Lighthouses method and a program designed to be used in the experimental PlanetLab network and it also evaluates achieved accuracy of the estimation.
