Virtual reality cyber gym
Nguyen, Van Phuc ; STODOLA,, Jiří (referee) ; Číka, Petr (advisor)
Diplomová práce představuje návrh a implementaci kybernetické tělocvičny pro virtuální realitu, která integruje imerzivní technologie pro modelování sítě. Na základě teorií z oblasti kybernetické bezpečnosti a sítí, virtuální reality, studie vytváří teoretický rámec. Je uvedena analýza SOTA, která přezkoumává použití VR v oblasti kybernetické bezpečnosti. Metodicky práce využívá Unreal Engine 5 pro vytvoření syntetického 3D prostředí a návrh interaktivních principů objektů ve virtuálním světě. V rámci praktické části práce je podrobně popsána architektura systému, interakce mezi IT komponentami, simulující podmínky reálného světa, přenesené do virtuální reality. Implementace zahrnuje programování platformy s důrazem na problémy a jejich řešení. Výsledky a diskuse analyzují efektivitu simulátorů pro výcvik v kybernetické bezpečnosti, rámovanou stanoveným teoretickým rámcem. V závěru studie jsou uvedena doporučení pro budoucí zlepšení a praktické využití.

Creation of laboratory exercises in the NS3 enviroment
Štefančík, Matej ; Langhammer, Lukáš (referee) ; Polák, Josef (advisor)
Diploma thesis provides an introduction to the ns-3 network simulator. It describes the basic abstactions and components of the instrument. This work further discusses the theory, which was applied during simulation creation. The concept of unicast, the issue of IP addressing and routing in networks are specificaly analyzed. The practical part is focused on the creation of four laboratory tasks within the scope of Advanced Communication Techniques. The first task is dedicated to the the issue of static unicast routing in the network. It clarifies the impact of metrics on the process of routing. The following task compares the different types of ICMPv4 and ICMPv6 messages. The third task discusses additional functions of the ICMPv6. Specifically, it focuses on five different types of ICMPv6 messages defined by NDP (Neighbor Discovery Protocol) and their role in the network traffic. The last task focuses on ensuring the quality of services (QoS) in wireless networks, by setting priorities and thereby dividing the traffic into different classes. Attention is focused on parameters such as throughput, delay and jitter.

Analysis of routing protocols used in MANET networks
Vala, Ondřej ; Hošek, Jiří (referee) ; Kubánková, Anna (advisor)
This diploma thesis is analysis of routing protocols used in MANET networks focusing on protocols OLSR, AODV and HWMP. The work consists of a theoretical and practical part. The theoretical part describes the routing protokols, which are used in MANET networks and their applications to FANET networks. In practical part, there are describes of created mobility model in the NS-3, which are used for comparison routing protocols on the created scenarios of mobility according to the qualitative parameters of the networks.

New laboratory exercises in OMNeT++ simulation enviroment
Petrůj, Jakub ; Sládok, Ondřej (referee) ; Langhammer, Lukáš (advisor)
This Bachelor thesis illustrates a draft and creation of two lab exercises in a network simulation environment of OMNeT++ with INET Framework extension on behalf of Communication Technologie course. Initialy, simulated environment itself is defined and, including NED language and its modules, then the process of simulation and analysis of its results are presented and discused. Further more this work describes theoretical network knowledge required to create the simulation and treat its results. The first methodical part of this work compares HTTP, FTP, Telnet and VOIP protocols in simultaneous and non simultaneous running, with increased occurance of errors on line or its complete outage. The second methodical part of this work observes dynamic network configuration using DHCP protocol more in detail. Futhermore, this part studies the question of both non-efective and efective subnetting and handles issues concerning static adressing of network.

Implementation of Communication Protocol Wireless M-BUS in Simulation Environment NS-3
Zeman, Kryštof ; Kováč, Dominik (referee) ; Mašek, Pavel (advisor)
The theoretical part of the thesis focuses on history and development of M2M com- munication, Wireless M-Bus protocol and NS-3 Network Simulator. It briefly describes characteristics of M2M communication, Wireless M-Bus and NS3 simulator. Physical and link layer of Wireless M-bus protocol are described in great detail to provide basics needed for understanding and orientation in the topic. Practical part of the thesis is focused on structure of used Simple Wireless module and basic simulation scenerio is built. The scenerio demostrates basic functions of the module.

Modeling of Signal Propagation in Wireless LTE and WiFi Networks in Indoor Deployment
Olbert, Jaroslav ; Mašek, Pavel (referee) ; Hošek, Jiří (advisor)
Masters thessis deals with the problematics of wireless signal propagation modeling inside buildings. The theoretical part of this thessis describes principles and methods of electromagnetic waves spreading in open areas and in indoor deployment. There are also described methods used for calculating the path of signal propagation ray-launching and ray-tracing. This part also includes description of an algorithm and equations used for simulating 5GHz WiFi signal propagation inside the Department of telecommunications corridors. Second part of this thessis includes a description of a NS-3 module mmWave, which was used for simulations of IEEE 802.11ad (WiGig) standard. There are also results of these simulations and their detailed description. At the end of this thessis comparison of these results with values gained by real environment measurements can be found.
