Abstract

The demand for stable and fast wireless networking is rapidly increasing. The new IEEE 802.11be amendment, also known as Wi-Fi 7, adds features that promise both higher throughput and lower latency. Among them, multi-link operation (MLO) and restricted target wake time stand out. Although each has been studied individually, their joint use remains largely unexplored, leaving open the question of how to distribute service periods (SPs) over multiple links. This thesis presents a centrally managed scheduler within an access point that coordinates a SP over 2.4 GHz and 5 GHz links. The solution is implemented in OMNeT++ using open-source MLO and INET frameworks and evaluated with up to 32 multi-link devices under varying network loads. Schedulers are evaluated by examining worst-case latency and jitter values, throughput comparisons and energy efficiency analysis. The study demonstrates that protected SPs shape the traffic in a way that provides predictable latency and jitter while providing more throughput, up to 53% in dense networks. It also achieves improved energy efficiency by 9.3% for senders and 36.1% for receivers when comparing MLO vs single-link operation on 5 GHz link. These results demonstrate that the new features, when used in conjunction with a central scheduler, can transform Wi-Fi 7 into a practical medium for time-sensitive applications. The implemented solution is an open-source contribution to the OMNeT++ community, enabling further research in this area.
