Research on Reliable Low-Power Wide-Area Communications Utilizing Multi-RAT LPWAN Technologies for IoT Applications
Štůsek, Martin ; Grochla, Krzysztof (oponent) ; Curado, Marilia (oponent) ; Hošek, Jiří (vedoucí práce)
This doctoral thesis addresses the “Research on Reliable Low-Power Wide-Area Communications Utilizing Multi-RAT LPWAN Technologies for IoT Applications”. Despite the immense progress in massive Machine-Type Communication (mMTC) technology enablers such as Low-Power Wide-Area (LPWA) networks, their performance does not have to satisfy the requirements of novelty Internet of Things (IoT) applications. The main goal of this Ph.D. work is to explore and evaluate the limitations of current LPWA technologies and propose novel mechanisms facilitating coverage planning and assessment. Proposed frameworks are fine-tuned and cross-validated by the extensive measurement campaigns conducted in public LPWA networks. This doctoral thesis further introduces the novelty approach of multi-RAT LPWA devices to overcome the performance limitation of individual LPWA technologies. The current implementation primarily focuses on diminishing the greatest multi-RAT solutions disadvantage, i.e., increased power consumption by employing a machine learning approach to radio interface selection.

Implementation of the LTE Cat-M Communication Technology Utilizing the NS-3
Le, Dinh Thao ; Kubánková, Anna (oponent) ; Mašek, Pavel (vedoucí práce)
The master's thesis addresses the Long Term Evolution Machine Type Communication (LTE-M) technology and its implementation in Network Simulator 3 (NS-3). As a member of the Low-Power Wide-Area (LPWA) technology group, LTE-M aims at facilitating the connectivity requirements for massive Machine-Type Communication (mMTC). The main goal of the thesis in the theoretical part is to clarify the characteristics of LTE-M and other technologies in the LPWA group, thereby highlighting their advantages, disadvantages and suitable use cases. The practical part contains the attempt to identify the limit of the network regarding the maximum number of connected devices. Furthermore, the implementation of the power saving features of LTE-M to the NS-3 LENA module is also described, and the obtained simulation results are discussed.
