Title: Modern Power Save Mechanisms in Wi-Fi Networks
Speaker: Ekaterina Stepanova, IITP RAS, MIPT.
Abstract: Energy efficiency is one of the serious challenges facing wireless networks today. It is important for many types of devices: IoT devices, battery-powered user devices such as smartphones and tablets, and even high-performance devices such as wireless VR headsets. In this talk, firstly we will discuss the basic power save (PS) mechanisms defined in the IEEE 802.11 standard and implemented in the majority of Wi-Fi devices. We will also discuss new PS mechanisms, such as Target Wake Time (TWT) and Wake-Up Radio (WUR), introduced in the IEEE 802.11ax and IEEE 802.11ba amendments to the Wi-Fi standard released this year. The first mechanism allows devices to schedule the frame exchange and the corresponding device awake time in advance. The second mechanism uses a low-power radio to transmit control signals. We will discuss the problems that arise while using these mechanisms and some ways to solve them.
Bio: Ekaterina Stepanova is a researcher at the Wireless Network Laboratory of IITP RAS and is presently working towards her Ph.D. degree at MIPT. She received the B.Sc. and M.Sc. degree in applied mathematics and physics from the Moscow Institute of Physics and Technology in 2017 and 2019 respectively. Her current research interests include IoT networks, power save mechanisms, analysis and development of wireless networks protocols, modeling of wireless networks.
The seminar is free and open.
