Implementation of LTE Cat-M Technology for Smart Measurement Scenarios
Tamentsev, Viacheslav
The requirements introduced in Directive 2019/944 of the European Parliament for smart metering scenarios, which differ from the ones defined in ITU-R M.2410, accelerated the integration of cellular technologies for the Internet of Things (IoT). With the release of cellular IoT (CIoT) technologies in the Czech Republic, recently LTE Cat-M, the focus shifts towards evaluating the performance in massive scenarios where thousands of devices are connected to one base station. This paper examines the feasibility of implementing LTE Cat-M communication technology in Network Simulator 3 (NS-3) to cover massive Machine-Type Communication (mMTC). The paper analyzes the capabilities of cellular modules within the selected simulation tool Networks Simulator 3 (NS-3), including the LENA module. First, simulation scenarios are created to validate and benchmark the performance of legacy LTE/LTE-A networks with attention to (mMTC) scenarios. The key output is the determination that the 4G networks are unsuitable for these scenarios. Further, based on the obtained data, the initial discussion on the requested implementation to support the LTE Cat-M in the NS-3 is provided, pointing out the exact changes associated with the physical layer.

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.

Implementation of the LTE Cat-M Technology for Smart Metering Scenarios
Tamentsev, Viacheslav ; Le, Dinh Thao (referee) ; Mašek, Pavel (advisor)
The Diploma work examines the feasibility of implementing Long-Term Evolution for Machine-Type Communications (LTE Cat-M) communication technology in Network Simulator-3 (NS-3) to provide massive Machine-Type Communication (mMTC). The paper analyzes the capabilities of cellular communication modules in the selected NS-3 simulation tool, including the LTE/EPC Network Simulator (LENA) module. In the theoretical part, it considers Low-Power Wide Area (LPWA) global networking technologies and their applications, including key aspects of the IoT Internet and Machine-to-Machine (M2M) communications. Special attention is given to analyzing the most common technologies in LPWA networks, such as Sigfox, Low-Power Wide Area Network (LoRaWAN), Narrowband Internet of Things (NB-IoT) and Long Term Evolution for Machines (LTE Cat-M). In the practical part, simulation scenarios are created to testing and comparing the performance of legacy LTE/LTE-A networks with focus on mMTC scenarios. The result is the determination that 4G networks are not suitable for these scenarios. Therefore, for such scenarios, the LTE/EPC Network Simulato Narrowband (LENA-NB) module is being used for modifications to the LENA module to meet LTE Cat-M requirements.

Implementation and Evaluation of the LTE Cat-M Technology Using the Network Simulator 3
Santa, Roman ; Komosný, Dan (referee) ; Mašek, Pavel (advisor)
Diplomová práca obsahuje teoretický úvod technológie LTE Cat-M. Prvá kapitola obsahuje opis generácií mobilných sietí s dôrazom na 5G mobilné IoT technológie. V druhej kapitole je popísaný proces štandardizácie Massive Machine-type Communication (mMTC) organizáciou 3GPP. Kapitola taktiež obsahuje aplikované IoT komunikačné scenáre a prehľadné porovnanie Low-Power Wide-Area (LPWA) technológií. LTE Cat-M technológia je stručne popísaná v tretej kapitole. Dôraz je kladený na fyzickú vrstvu a alokáciu zdrojov. Simulačné prostredie a použité moduly sú objasnené na začiatku štvrtej kapitoly. Štvrtá kapitola sa ďalej zaoberá popisom jednotlivých simulačných scenárov a výsledkami simulácií. Simulácie sú rozdelené na dve hlavné kategórie, simulácia počtu koncových staníc a simulácia spotreby energie s využitím režímu úspory energie (PSM).

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.

Analysis and prediction of data traffic in mobile ad hoc network
Konečný, Daniel ; Koutný, Martin (referee) ; Hošek, Jiří (advisor)
The diploma thesis „Analysis and prediction of data traffic in mobile Ad Hoc network“ focuses on the radio propagation models of services in MANET (Mobile Ad-hoc) networks. It describes MANET networks and covers the theoretical analysis of routing protocols, radio wave propagation and propagation models of simulation enviroment NS-3 (Network Simulator 3). Furthermore, there is processed the creation process of model MANET networks with the routing protocol AODV (Ad Hoc On Demand Distance Vector) in the simulation environment NS-3. For analysis purposes there were implemented new functions to capture value of SNR (Signal to Noise Ratio) and throughtput. For this reason a physical layer of one of NS-3 model was modified. As an result there is a simulation build that compared several number of propagaion models.
