Resource Consumption Forecasting and AI-Driven Service Scaling in 5G Environments.

In the 5th generation mobile networking, new types of services with high resource consumption and strict requirements in terms of quality of service (QoS) e.g. ultra low latency, high bandwidth, availability e.t.c, have emerged. The current thesis will exploit Machine Learning (ML) techniques so as to forecast future resource-related requests and proactively adapt the network resources in accordance to service resource demands (e.g. disk storage, memory size, cpu capacity, network bandwidth) in order to efficiently support service operation and ensure no Service-Level Agreement (SLA) violation.

Network Anomaly Prediction and Forecasting in 5G Environments.

Securing the networks of tomorrow is set to be a challenging domain due to increased network heterogeneity, increased use of virtualisation technologies and distributed architectures. The current thesis will exploit well known Machine Learning (ML) techniques, targeting to to detect anomalous network traffic. To validate the effectiveness of the trained models, normal and anomalous network flows from a simulated environment using NS-3 tool have been collected.

Automation on the flows assigned to the New Radio network backbone in order to handle movement of the clients

The increase in smart technologies e.g. smart cars, smart drones etc. has made imperative the handling of the movement of such devices from the side of the network. In this thesis we will explore the automation of user equipment etc. in the network and the prediction of movement in order to handle the Quality of Service though out the movement of each device and handle the handover using Machine Learning techniques.

Exploration of innovative AI-Driven Clustering Mechanisms towards Contextual Profiling in 5G Environments.

The 5th generation mobile networking is going to provide numerous advantages (e.g V2X Applications,Massive IoT Deployments) when compared to the existing 4G technologies . Additionally, there is a plethora of heterogeneous data sources that if managed properly, can provide considerable gains for the network. This thesis will explore different clustering mechanisms in order to collectively group this diverse information and create contextual profiles which will in turn provide useful insights with regards to network optimisation and management.

Predictive Contextual Profiling in 5G Environments using Distributed Machine Learning Techniques.

The advancement of technology and especially the introduction of the 5th generation mobile networking; introduces an ever-increasing amount of data flows. Managing and analysing this amount of data in a distributed manner is of major importance in order to proactively take measures to ensure a smooth and uninterrupted regardless-of-network-operation scale. This thesis will explore different Distributed Machine Learning Techniques towards network profile creation which will in turn provide improved accuracy, performance and larger input data size scaling.

Implementation of simulation scenarios for 5G V2X using NS-3 and SUMO

NS-3 is a discrete-event network simulator,targeted primarily for research and educational use. SUMO is used for simulating urban mobility, which can be used in any NS-3 simulation scenarios. The target is to develop and explore different simulation scenarios, exploiting advanced concepts and generate results for 5G V2X simulations, using the milicar module of NS-3. These scenarios must include buildings and a relatively large amount of UEs.

Creation of a “free” interference wireless 5G and beyond network topologies

With the expansion of the IoT concept and with the increase in the use of devices that use the wireless range of communications (Wi-Fi, LTE, 5G and beyond) it is necessary to find a solution for the placement of access points without interference between them. The current thesis will exploit the use of Artificial Intelligence combined with Neural Networks in order to provide solutions for better service delivery.
