This thesis deals with simulation of routing protocol OSPF in simulation software called OMNeT++. OMNeT++ is a discrete modular simulator mostly used for simulation of computer networks. This thesis includes theory needed for an understanding of the functionality of OSPFv2 and changes in OSPFv3 for IPv6, which are implemented in the model itself. Moreover, thesis contains the configuration of OSPFv3 protocol on topology created from Cisco devices following by analysis of previous source files, state of implementation and its further extension. Thesis is finished with functionality testing and evaluation of results.

This Master's thesis deals with modeling and simulation of BGP protocol within the OMNeT++ environment. The BGP protocol is described with employed data structures and the finite state machine of BGP peering. Next, the basic configuration is outlined involving the setup of the BGP protocol on Cisco devices. Further, BGP for OMNeT++ state-of-the-art is investigated together with its lack of functionality and issues. The second part of this thesis deals with design, implementation, and testing of the new functionality of BGP protocol and simulation models. The last section describes the overall achieved results.

Quality of service (QoS) is an important consideration in networking, but it is also a significant challenge. Providing QoS guarantees becomes even more challenging when you add the complexities to the network like voice and video applications. This master's thesis focuses on QoS modeling and simulation in discrete event simulation system OMNeT++. The implementation of multiple techniques for QoS simulation is added to OMNeT++ within this work. All implemented modules are validated against the QoS tools on real routers. The last part of the work presents the possibility of QoS simulation in newly implemented modules.

The work deals with communication protocols of the IEC 61850 standard. The protocols GOOSE (Generic Object Oriented Substation Events), SMV (Sampled Measured Values) and MMS (Manufacturing Message Specification) are described. The protocols are used to create a simulation network, which is described in this work. The simulation network is created in the OMNeT ++, program installed in the Ubuntu virtual environment.

The thesis deals with dynamic bandwidth allocation in passive optical networks of NG- PON2 standard. The paper also describes the so-called. triple play services and the practical part is a simulation of these services in passive optical networks NG-PON2 in the simulation environment OMNeT ++. As part of this work modules for passive optical network NG-PON2 were created as an expansion of project INET. Namely ONU, OLT and splitter modules were created. The first four chapters are theoretical and descibe older standards PON networks, further NG-PON2 networks and DBA algorithm then describes triple play services and explains their current status respectively. In another part a description of the programm OMNeT++ a description of the structure of simulation models. The practical part contains a description of modules, implementation of DBA algorithm and its modification, design simulated topology and detailed description of the configuration simulation. At the end of the practical part presents the results of simulations with the corresponding explanations.

This master thesis deals with the implementation of the RIPng routing protocol in the OMNeT++/INET environment. It describes the RIPng protocol and its specifics on the Cisco devices. It clarifies important concepts such as IPv6 and distance-vector routing protocols. The thesis also describes the OMNeT++ environment and the INET Framework, where it focuses on the current status of implementation of the components required for the RIPng protocol integration.

The network simulation allows analysis of the computer networks behavior and configured protocols. This thesis focuses on the EIGRP routing protocol and its integration into the OMNeT++ simulation enviroment. The text includes a detailed description of the protocol and its configuration on Cisco devices. Furthermore, the text focuses on design of extension that supports routing protocol. The following describes implementation of the protocol according to design. Finally, the implemented solution is compared with the output of real devices.

In der vorliegenden Bachelorarbeit soll ein Framework zur Umsetzung des Resourcebased Application Clustering Approach in die OMNeT++/INET Simulationsumgebung integriert werden. Der Ansatz verfolgt das Ziel, Anwendungen in einem verteilten Sensornetzwerk in einem Cluster geeigneter Knoten zu verteilen. Ausgewählt werden sollen diejenigen Knoten, die über die besten Ressourcen verfügen. Als Grundlage für die Integration dient eine Implementierung auf einem Mikrocontrollerbasierten Demonstrator. Dieses Framework wurde erfolgreich in die INET-Modellbibliothek integriert. Als Ergebnis entsteht außerdem ein Szenario, indem ein Netzwerk Anwendung durch das integrierte Framework verteilt. Die vorliegende Arbeit kann als Grundlage für die weitere Evaluierung des Resource-based Application Clustering Approach genutzt werden.
