Originální abstrakt

The geolocation techniques based on latency use the relation between delay and distance. This paper describes a way of improving the accuracy of these methods by a detailed analysis of delay sources along the physical path from source to destination. The fundamental of geolocation techniques are described and the pros and cons of these methods are mentioned. This paper takes a close look at delay sources and the variable parameters of the communication chain. The usual size of delay and the path length were obtained from measurement in the Czech academic network (CESNET2). The results presented in this paper are the computed optimal latency per hop and the ratio of real length of cable to straight distance between cities. The same measurement and calculation was done in the Internet. Future work will utilize findings of this work for the improvement the accuracy of geolocalization techniques.
