Wireless Networks Laboratory Presents Novel Results on Future Wi-Fi at the 2018 IEEE International Conference on Communications


WNL is going to present the recent results on the schedulers for IEEE 802.11ax networks, which are currently under development. The IEEE International Conference on Communications (ICC) will be held on May 20–24, 2018, in Kansas City, MO, USA. It is one of the most significant scientific events for the networking and communications community, a must attend forum for both industrials and academics working in this area.


At IEEE ICC 2018, the Wireless Networks Lab will present the recent results on the schedulers for future Wi-Fi, namely IEEE 802.11ax, which is being developed by IEEE 802 LAN/MAN standards committee. Besides increasing user perceived throughput of Wi-Fi networks by a factor of four, it aims at improving performance of wireless networks in dense deployment, which is a highly important scenario. To orchestrate a swarm of Wi-Fi stations and improve overall performance, IEEE 802.11ax shifts many decision-making algorithms from stations to access points. It is the access points that schedules channel time and specifies the transmission parameters for both uplink and downlink.


In the paper entitled ‘OFDMA Uplink Scheduling in IEEE 802.11ax Networks’, Dmitry Bankov, Andrey Lyakhov and Evgeny Khorov have studied the benefits of OFDMA for IEEE 802.11ax. Despite the fact that OFDMA is not a new technology and it has been used in cellular networks for many years, many existing results and solutions cannot be directly applied to Wi-Fi networks because of some peculiarities at 11ax. Supported by Russian Science Foundation grant, researchers have investigated how to schedule OFDMA resource units in the best way to improve users’ quality of experience. They have proposed a general method to build schedulers, which try to maximize various utility functions corresponding to different customer requirements, and proved the high gain of the designed schedulers with respect to the existing ones.


IEEE International Conference on Communications (ICC) is one of the IEEE Communications Society’s two flagship conferences dedicated to driving innovation in nearly every aspect of communications. Each year, about 3,000 scientific researchers and their management submit proposals for program sessions to be held at the annual conference. After extensive peer review, the best of the proposals are selected for the conference program, which includes technical papers, tutorials, workshops and industry sessions designed specifically to advance technologies, systems and infrastructure.


Wireless Networks Lab is a ‘Megagrant’ lab established in 2017 around the project on Cloudified Wireless Networks for 5G and beyond, led by Prof. Ian F. Akyildiz. The team regularly reports at leading IEEE conferences, runs industrial projects and contributes to standardization of wireless networks.
