Wireless Networks Laboratory presents latest results on Wi-Fi halow at the 19th IEEE International Symposium on a World of Wireless, Mobile And Multimedia Networks

WNL team is presenting latest results, related to IEEE 802.11ah Restricted Access Window mechanism, on the 19th IEEE International Symposium on a World of Wireless, Mobile and Multimedia Networks (IEEE WoWMoM 2018). IEEE WoWMoM 2018 is held on June 12-15, 2018, in Chania, Greece. It is significant and important event for the wireless communications community, addressing research challenges and advances in the areas of wireless, mobile, and multimedia networking as well as ubiquitous and pervasive systems.

IEEE 802.11ah (or Wi-Fi HaLow) is a new standard, published in 2017. Called to meet the growing needs of IoT, Wi-Fi HaLow offers networks with over 8000 stations connected to one access points within 1km range. To reduce contention in such big networks Wi-Fi HaLow introduces  grouping mechanism, known as Restricted Access Window. This mechanism is the focus of interest of a WNL team.

On the IEEE WoWMoM 2018 WNL team is presenting paper named ‘Two-Slot Based Model of the IEEE 802.11ah Restricted Access Window with Enabled Transmissions Crossing Slot Boundaries’, written by Evgeny Khorov, Andrey Lyakhov and Ruslan Yusupov. The paper describes a mathematical model of a Restricted Access Window in so-called cross-slot boundary mode. By using Restricted Access Window mechanism access point divides stations into groups and allocates for each group equal RAW-slots within Restricted Access Window. Enabling the cross-slot boundary mode allows stations to make one additional transmission attempt which ends outside allocated RAW-slot. The questions is whether it is worst to enable or disable this option, as it increases contention for the channel which results in a lower battery lifetime for autonomus devices, but in principal may increase channel resourse utilization and the network throughput correspondingly. WNL team is going to answer that question on the IEEE WoWMoM 2018 conference.

The 19th IEEE International Symposium on a World of Wireless, Mobile and Multimedia Networks offers a four-day technical program including keynote speeches, hot-topic panel sessions, tutorials, demonstrations, and PhD forum. Several workshops will be held in conjunction with the symposium. Workshop papers will be included and indexed in the IEEE Digital Library (IEEE Xplore), showing their affiliation with IEEE WoWMoM. The conference, which will take place in Chania, one of the most beautiful cities of Greece, also provides a high quality social events program, including a welcome reception and a gala dinner.

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.
