Simulation and Optimization of Flexible 5G Networks with Wireless Access Backhaul

This thesis investigates Wireless Access Backhaul (WAB) architectures for the dynamic deployment of mobile 5G connectivity bubbles. WAB nodes deployed on vehicles, UAVs, or other mobile platforms can provide local 5G access while dynamically exploiting heterogeneous backhaul technologies, including terrestrial and non-terrestrial networks.

Building on an existing WAB simulator developed in ns-3 with the 5G-LENA module, the thesis will explore techniques for managing and optimizing these flexible networks under dynamic and unreliable conditions. Possible research directions include the integration of terrestrial and non-terrestrial backhaul, adaptive radio access reconfiguration, interference and spectrum management, mobility and handover optimization, and intelligent network planning and management.

The goal is to investigate how WAB nodes can dynamically adapt their configuration and connectivity to provide reliable and efficient 5G coverage in scenarios such as emergency response, crowded events, transportation, and remote areas.
