IPv6 Geolocation and Visualization
Suchomel, Tomáš ; Veselý, Vladimír (referee) ; Matoušek, Petr (advisor)
This master's thesis is focused on geolocation and visualization of IPv6 addresses. Several current approaches to geolocation have been discussed. Its main goal is to design geolocation database with regular updates with ability to visualize geographic location of the IPv6 address on the world map. Implemented system is gathering data about IPv6 prefixes from public Whois database. Gathered geographical addresses are mapped into coordinates by Google Maps Geocoding API. All gathered data are being saved into database together. Locations of IPv6 addresses are visualized via web-based Google Maps API. Moreover, the density mapping of IPv6 address blocks in particular countries can be visualized too.

Visual Geolocation of a Stationary Camera
Šimurda, Pavel ; Španěl, Michal (referee) ; Herout, Adam (advisor)
Tato práce se zabývá a analyzuje možnosti, kterými je možno zjistit geografickou polohu ze snímků nebo videa pouze za použití vizuální informace z obrazu. Výsledkem práce jsou dvě rozdílné metody geo-lokalizace. První z nich pracuje na principu hledání časů východu a západu Slunce. Hlavní výhodou této metody je její univerzálnost. Funguje s jakoukoliv kamerou umístěnou v externích prostorech a nevyžaduje přítomnost žádných specifických objektů ve scéně. Pro správný výsledek je třeba alespoň celodenní záznam z kamery. Výsledky jsou uspokojivé za každého počasí. Druhá metoda pracuje na základě analýzy stínů ve scéně. Správnou pozici je možno určit, s poměrně velkou přesností, pouze na základě dvou snímků pořízených v různém čase. Tato metoda vyžaduje přítomnost dvou objektů v obraze, které vrhají stín. Přesnosti výsledků navržených metod jsou vyhodnoceny a porovnány. Z výsledků vyplývá, že obě metody lze úspěšně použít pro odhad geografické polohy. Dále byla v rámci práce pořízena rozsáhlá datová sada obrazových sekvencí z volně přístupných webových kamer.

Localization of geographic position attacker in the Internet
Kubalík, František ; Komosný, Dan (referee) ; Verner, Lukáš (advisor)
This thesis deals with the evaluation of the geographical location of the Internet using delay and implementating method Octant. The first part is devoted to familiarization with the principles of evaluation of the physical position of the stations on the Internet, with a focus on active methods for IP Geolocation. Here it is more space devoted to geolocation Octant algorithm and a more detailed explanation of its principles. At the end of the first part is also familiar with the experimental network PlanetLab. The second part describes the design and implementation of the program in programming language C#, which locates the searched local station with mentioned localization algorithm Octant. Description realization is accompanied by explained examples of the classes with a detailed explanation. Here are also the results of the methods on selected IP addresses of stations with known locations to detect errors or deviations of method from the actual position of searched station. At the end of this section is a comparison with other active as well as passive geolocation methods.

Geolocation of Internet nodes based on communication latency
Horák, Michael ; Balej, Jiří (referee) ; Komosný, Dan (advisor)
This thesis covers the topic of determination of geographical location of a host in internet network while utilizing measurement of the end to end delay and implementation of Constraint-Based Geolocation. Gradually I go through issue of the delay in computer networks and ways how to measure it. Next chapter describes a few ways to geolocate host in internet network with emphasis on the CBG method. Another chapter is dedicated to describing a way to project spherical coordinates to the two dimensional space, which has been used in implementation of geolocation method. Chapter about implementation builds upon the facts given in previous chapters while functions of the program written in the JAVA programing language are being explained. Two similar geolocation methods were implemented. By comparing the results gained by implementation, new method of geolocation is proposed and devised. It combines properities of both previous methods. There are results of the implemented methods and their comparation to the one of the source documents used in creation of this thesis in summary section.

Localization of IP stations based on model of probability delay measurement
Tropp, Peter ; Komosný, Dan (referee) ; Verner, Lukáš (advisor)
The master thesis is dealing with Internet host localization methods, more exactly with determining geographical position of the unknown Internet host connected to the network using RTT delay measuring. The first part is dealing with description of RTT delays that may occur in the network and tools for their measurement. The next is part of thesis is devoted to description of two kinds of localization methods. Ones that are using existing data to determine the position of Internet host also called passive methods, and others that are using RTT delay measurement, also called active methods. The main part is focused on GeoWeight method which is based on geographical localization estimation of Internet host. It is based on RTT delay measurement using the principles of CBG method, enhanced by introduction of the theory of weights according to the probability of the target Internet host. The last part is describing the application that was made to determine the geographic localization of the target Internet host using GeoWeight method. The application was afterwards tested by measuring RTT delay in PlanetLab experimental network. At the end the final measured results were compared with other localization methods (CBG, Octant, SOI, GeoIP).
