Multi-link operation for low-latency

Next generation applications will have strict network requirement, such as higher throughput and low latency. As Wi-Fi continues to grow, it needs to adapt to these new requirements. This thesis focuses on latency reduction over Wi-Fi networks and one of the main features of the upcoming Wi-Fi 7: Multi-Link Operation (MLO). With MLO, devices can associate to an Access Point over multiple links at the same time and transmit over multiple channels simultaneously, multiplying their bandwidth. This feature can also be used to improve network delay, as using independent backoffs in different links allows the device to adapt and choose the least congested link opportunistically. We focus on this aspect of MLO, showing that this can lead to an order of magnitude delay reduction over the worst-case delay in Single-Link Wi-Fi. We also analyze the use of MLO to deliver the traffic of Cloud gaming and Virtual Reality applications.
