Ray Tracing is a deterministic propagation modeling approach that estimates the signal power received in specific geographical locations based on a thorough consideration of the 3D environmental factors that influence signal propagation. This high accuracy of Ray Tracing is however at the cost of a high computational load due to the complexities of...
Cellular networks provide digital communications for more than five billion people around the globe. Besides, their openness to the general public, opaqueness, and complexity have exposed cellular networks to attacks that have tremendously grown over the previous decades. According to the Communication Fraud Control Association's 2021 report, world...
Addressing transport-layer issues in cellular networks is still a hot research topic, despite the fact that a wide range of solutions have been proposed over the last decades. One reason that could explain this phenomenon is the difficulties in the real-world adoption of the proposed solutions as they require either drastic changes in the cellular ...
The main focus of this thesis is on modeling, performance evaluation and system-level optimization of next-generation cellular networks empowered by Unmanned Aerial Vehicles (UAVs) by using Machine Learning (ML). In addition, the emerging technology of Integrated Sensing and Communication is investigated for application to future UAV wireless netwo...
Du fait de la confidentialité des données que contiennent les traces cellulaires CDRs (Call Data Records), leur obtention est soumise à des lois strictes qui limitent leur accessibilité aux chercheurs, et leur utilisabilité même lorsqu'ils sont disponibles. Pour pallier à ce manque, dans cet article, nous nous intéressons à la production de traces ...
The pervasiveness of mobile devices equipped with internet connectivity and positioning systems leads us to regard them as a valuable resource to leverage. In this thesis, we tackle the use of mobile devices from a new perspective. We consider the extension of the capacity of the MEC by using the available resources of mobile devices beyond the edg...
The proliferation of sophisticated applications and services comes with diverse performance requirements as well as an exponential traffic growth for both upload and download. The cellular networks such as 4G and 5G are advocated to support this diverse and huge amount of data. This thesis work targets the enforcement of advanced cellular network s...
Non-orthogonal multiple access (NOMA) is a promising technology to increase the spectral efficiency and enable massive connectivity in future wireless networks. In contrast to orthogonal schemes, such as OFDMA, NOMA can serve multiple users on the same frequency and time resource by superposing their signal in the power domain. One of the key chall...
Full-duplex (FD) is a principle in which a transceiver can receive and transmit on the same time-frequency radio resource. The principle was long held as impractical due to the high self-interference that arises when simultaneously transmitting and receiving in the same resource block. When assuming perfect self-interference cancellation, FD can po...
We live in the digital era where the Internet has become an essential part of our daily lives. With more than 750 million connected households and over 6.8 billion mobile subscribers, mobile networks are dominating the Information and Communication Technology (ICT) sector with more than 75%. The trend is of further increase and appears to have no s...
