Node localization on the Internet using domain name system
Dvořák, Petr ; Müller, Jakub (referee) ; Komosný, Dan (advisor)
This paper describes various systems that are used to predict delay among nodes . It focuses on systems using for prediction delay artificial coordinate systems, and on the systems, which use physical measurements of delay. Primarily, however, it deals with the King method, which uses the system for translation of domain names - DNS (Domain Name System) to predict the delay. Next, the principle of the King method is outlined in detail. Practical part includes a description of the two created simulations in program Matlab. The first application described simulates the King method principle. The second simulation is then tasked with creating 2D geometric space in which nodes and DNS servers are randomly generated. The result is dependence of RTT prediction accuracy on the number of randomly generated DNS servers. Based on this dependency the method King is compared with other methods in the end.
