Master’s thesis includes knowledges about mobility support in IPv4 networks and studies abilities for mobility support in IPv6 networks. Describes protocols for mobility support, their functions and topologies like MIPv6 (RFC 3775), FMIPv6 (RFC 5568), HMIPv6 (RFC 5380) and F-HMIPv6. The thesis contains a design of the simulation MIPv6 in the OPNET Modeler program and the measured results are explained. There are analysis of source code for mobility support in MIPv6 too, which were used for design a new protocol according to FMIPv6 in the OPNET. The following parts of the proposal have been successfully resolved. The link-layer events detection, which triggers FMIPv6 protocol and implementation of two new types of messages, RtSolPr and PrRtAdv. Knowledges from this thesis could be used for next development of FMIPv6 in the OPNET. But could be used for generaly development new protocols working at network-layer too.

This thesis deals with data transmission applications in the converged network, focusing on the WiFi network IEEE 802.11. The theoretical part describes the cause and nature of converged networks. One chapter is devoted to a description of IEEE 802.11, which is next to different standards and options described architecture, coordination and access network QoS solution to that standard. The research is based on custom design converged networks, and WiFi elements in the environment of graphic simulation software OPNET Modeler. In the proposed network was also simulated the operation of services such as voice, video conferencing, FTP and HTTP streaming. Results of simulation data traffic in the network are then analyzed. At the Conclusion of the thesis, is in OPNET Modeller program created the role of laboratory. The essence here is the comparison of operating a converged network, with and without quality support services.

This thesis deals with usage of bypass diodes in photovoltaic panels. Familiarize us with principles of photovoltaic modules and functions, their electrical characteristics and features. The central objective of this work is description of influence of bypass diodes on particularly shading photovoltaic panels and its volt-ampere characteristics. By the help of created software in Agilent VEE 8.0 simulate the shading panel and compare with real measurement.

Diploma thesis is dealing with access networks, especially with the passive optical network. The theoretical part is a list of different types of passive optical access networks, including theirs basic description, which then goes on to feature connectivity options for optical units, customers, including topology of distribution network. Analysis of different types of networks and the possibility of physical and logical design is the basis for successful design and prepa-ration of future optical access networks. Practical part is devoting to data analysis of measurement existing metropolitan network to be used for construction of optical access network in Brno, Ţlutý kopec – Preslova location. Data evaluation showed possibility of connecting with already installed network hence is created proposal of optical access network mentioned before. Selected location is analysed in detail and illustrated on situational scheme of location and customers, whose will be passive split-ters to central office. Consequently is developed project of optical access network based on data analysed date from measurements. Project is study and description of planned solution of optical access network in order to bring Triple Play services to customers. Within the interpretation of the feasibility of the project and verification physical layer pa-rameters of network was made a simulation in OptiSystem. The possibility of successful op-eration of the optical access network with the attributes entered in its design is approved in accordance with the evaluation results. The proposed network is passive in character of GPON standard, and the text describes in detail physical layer, proposed transmission speed, wave and attenuation plan of optical net-work. The work implies a specific line of HDPE ducts and microducts in them, including drawing the maps and identification in-depth. The work contains a description of the elements that are installed on the route – the number, type and eventually its length. Diploma thesis is introducing the technology and construction sequence of access network leading to its opera-tional state.

This thesis is focusing on the second satellite digital TV standard, DVB-S2. It deals with the principle of the digital TV and the first standard DVB-S. It also describes the very beginning and characteristics of the DVB-S2, new technologies in use, architecture and the individual topics are then explained more in detail. The thesis also contains the program of transmission simulation of DVB-S2 in MATLAB. In the laboratory of television technology UREL, two standards were measured and compared with the values obtained from the program. The functionality of the program and the benefits of DVB-S2 were verified afterwards.

This work deals with a creation of model of synchronous generator in programmes such as Simplorer and Maxwell, and also its operation in an insular operation. In the paper are described Maxwells equations for solving electromagnetic field, theory of synchronous machine, further are briefly described a simulation programmes which were used. In the next part of work is described production of geometric model of generator and its later electromagnetic analysis in the Maxwell programmes environment. For a simulation of generators operation in insular operation were chosen 2 cases. The first case simulates an operation of generator at the step change of residence of R-L load, the second simulation an automatic regulation of voltage at the step change of residence of R-L load. The simulations were running in the Simplorer programme and at link simulation Maxwell Simplorer programmes.
