Simulation of IP node localization, using Vivaldi and GNP algorithms
Sulík, Peter ; Komosný, Dan (referee) ; Müller, Jakub (advisor)
The work deals with the issues of network coordinate systems. The first chapter is devoted to a brief analysis of this systems and requirements placed on them. Furthermore, it deals with features of Vivaldi algorithm and its three versions: a centralized algorithm, algorithm with constant and adaptive time step. Subsequently it describes the GNP system and eash step of Nelder-Mead method for nodes localization. Next to it a developed simulation library is presented with its own graphical user interface for testing of these algorithms, which is capable of handling RTT responses database amongst individual IP network members. Simulations performed on data from PlanetLab network are evaluated in the conclusion.

Features and use of IPv6 and MIPv6 protocols
Sulík, Peter ; Polívka, Michal (referee) ; Skořepa, Michal (advisor)
The thesis deals with IPv6 protocol problematic and with mobility support in this protocol. In the first part are described basic IPv6 attributes and differences compared to IPv4 protocol. In the second part, the MIPv6 protocol is described in detail and mainly the advantages in wireless networks usage. Most of the part is dedicated to routing mechanism problematic of Bidirectional tunneling and Route Optimisation. Thereafter, networks are simulated in OPNET Modeler software to demonstrate the attributes of MIPv6 protocol. In conclusion, the simulations results are evaluated and also advantages of Route Optimization routing in networks.
