Enabling Intelligent Network Management Through Multi-Agent Systems: An Implementation Of Autonomous Network System, Petro Mushidi Tshakwanda
Enabling Intelligent Network Management Through Multi-Agent Systems: An Implementation Of Autonomous Network System, Petro Mushidi Tshakwanda
Electrical and Computer Engineering ETDs
This Ph.D. dissertation presents a pioneering Multi-Agent System (MAS) approach for intelligent network management, particularly suited for next-generation networks like 5G and 6G. The thesis is segmented into four critical parts. Firstly, it contrasts the benefits of agent-based design over traditional micro-service architectures. Secondly, it elaborates on the implementation of network service agents in Python Agent Development Environment (PADE), employing machine learning and deep learning algorithms for performance evaluation. Thirdly, a new scalable approach, Scalable and Efficient DevOps (SE-DO), is introduced to optimize agent performance in resource-constrained settings. Fourthly, the dissertation delves into Quality of Service (QoS) and Radio Resource …
Multicarrier Modulation Using Discrete Fractional Fourier Transform, Amir Raeisi Nafchi
Multicarrier Modulation Using Discrete Fractional Fourier Transform, Amir Raeisi Nafchi
Electrical and Computer Engineering ETDs
The focus of the research was to investigate the application of the discrete fractional Fourier transform (DFRFT) in communication systems. We investigated the compactness of the Gauss-Hermite like eigenvectors of the DFRFT and showed how a multi-carrier modulation system could benefit from it. This led to identifying an affine DFRFT. We proved the circular convolution property for the proposed DFRFT. Using this affine transform, we were able to design an orthogonal frequency division multiplexer (OFDM) communication system. In the process of implementing the OFDM, we developed a method for fast computation of the DFRFT using the chirp-z transform. Using the …
Intelligent Internet Of Things Frameworks For Smart City Safety, Dimitrios Sikeridis
Intelligent Internet Of Things Frameworks For Smart City Safety, Dimitrios Sikeridis
Electrical and Computer Engineering ETDs
The emerging Smart City ecosystem consists of a vast edge network of Internet of Things (IoT) devices that continuously interact with mobile devices carried by its citizens. In this setting, the IoT infrastructure, apart from the main communications facilitator, acts as a crowdsourcing mechanism that collects massive amounts of user data, and can support public safety applications for the Smart City. In this thesis, we design and analyze learning mechanisms that extract intelligence from crowd interactions with the wireless IoT infrastructure, and optimize its energy efficiency while operating as a public safety network. First, we deploy a multi-story facility testbed …

Applying Heterogeneous Teams Of Robotic Agents Using Hybrid Communications To Mapping And Education, Jonathan M. West
Electrical and Computer Engineering ETDs
Robotic agents are being increasingly utilized to carry out tasks that are difficult or dangerous for humans. Many of these missions are best performed by heterogeneous teams of agents with various individual abilities. Communication among agents and with operators is a critical element in the performance and efficiency of these missions. Although radio frequency communications dominate the robotic networking field, they are limited in range and bandwidth due to spectrum congestion and subject to interference from noise or hostile jamming and can be intercepted. Optical communication has many advantages such as higher bandwidth and focused beam, however the line-of-sight requirement …
