Ekaterina Stepanova - Study of power saving methods in wireless local area networks of the IoT

Power saving is one of the most important issues for Wi-Fi networks, so the Wi-Fi standard includes a number of mechanisms to reduce energy consumption. Target Wake Time (TWT) and Wake-Up Radio (WUR) are the most advanced power save mechanisms. These mechanisms work by scheduling power saving station (PS STA) service periods so that during the remaining time, STAs can turn off the Wi-Fi radio to save power. However, in the disabled state, the PS STA cannot receive network information frames and therefore cannot synchronize its clock with the AP’s clock. Therefore, the clock drift can significantly affect the efficiency of TWT and WUR. The talk presents the main results of the thesis, which is dedicated to study the efficiency of TWT and WUR power save mechanisms in heterogeneous Wi-Fi networks with the clock drift.
