Advanced Segmentation of a Simulated Network
Slávik, Mark ; Komosný, Dan (referee) ; Benedikt, Jan (advisor)
The diploma thesis deals with the simulation of available routing protocols in the NS3 simulator and in the Quagga module. The functions of simulated routing protocols are described in the theoretical part. In the practical part, the functionality of the NS3 simulator and the RIP, OLSR and OSPF, BGP routing protocols from the Quagga module are introduced using a simple topology. Finally, the network is extended and several subnets are added. Using available analysis tools, the network is subsequently analyzed and evaluated with different scenarios.

Modelling of Mechanisms for Multiple Access to Mobile Network
Tinka, Zdeněk ; Mašek, Pavel (referee) ; Hošek, Jiří (advisor)
The diploma thesis „Mechanisms modelling of multi access into mobile wireless network“ is focusing the wireless network. The diploma thesis contains basic network topology of wireless standard 802.11g and utilizes key identificators of mobile node in dependency on the distance and collision controlling function for simulation purposes. In the next part of this thesis is created LTE mobile network topology, which serves for finding key identificators. In the last part is created offload topology containing both - 802.11g and LTE network. As the result are implemented offloading algorithms, which ensure data traffic switching based on comparing 802.11g and LTE key identificators. Automatically generated and shown figures providing the key statistics are the main output of this thesis.

New simulation scenarios in NS3 environment
Bureš, František ; Kubánková, Anna (referee) ; Jeřábek, Jan (advisor)
Cílem bylo navrhnout dva simulační scénáře v prostředí NS-3. První scénář obsahuje ARQ (Automatic Repeat Request) metody v TCP (Transmission Control Protocol). Je v něm porovnání Stop-and-Wait, Go-Back-N a Selective-Repeat metod. Teoretická část obsahuje TCP a ARQ. Druhý scénář je o způsobech přenosu zpráv. Vytvořený scénář převážně s komutací paketů a buněk a teoretické základy jsou obsaženy v práci. Je v něm porovnání metod komutací s různou velikostí paketu/buňky, počtem uzlů a důsledek zpoždění v každé metodě. Scénáře jsou ve formě laboratorní úlohy s instrukcemi k vypracování.

Performance Metrics Evaluations for Selected Proactive Routing Protocols in Smart Grid Neighbourhood Area Wireless Mesh Network
Anderson, Enock
The smart grid communication network has improved energy optimization delivery from generation, transmission, and consumption. The introduction of wireless mesh networks in the area of Neighbourhood ad hoc Networks has contributed to the quick and cost-effective way of deployment in the areas where back-haul technology like fiber optic is expensive and challenging and may not be timely. The IEEE 802.11s standard-based wireless mesh network associated with the hybrid wireless mesh protocol is highly recommended due to its extended functionality. However, the hybrid wireless mesh protocol based mesh networks can not guarantee the quality of service in such an environment. The OLSR (Optimised Link State Routing) protocol outperforms the Reactive protocol in ad hoc Networks when transmission quality is required. This paper proposes the adaptation of Extended Transmission Control with OLSR as the optimized protocol for such an environment in neighbourhood ad hoc networks. The simulation study was carried out using the NS3 simulator to evaluate the performance of OLSR and OLSR-ETX (OLSR with Expected Transmission Count). The results confirm the viability of this protocol for neighbourhood ad hoc networks and also outperform similar simulation using NS2. The implementation of OLSR-ETX in the neighbourhood ad hoc networks rural environment will increase reliability and improve Demand Response DR in Smart Grid.
