Collision-Based Up-Link OFDMA Random Access Mechanism for Wi-Fi 6

open access: yesIEEE Access, 2023
The IEEE 802.11ax standard defines High-Efficiency WLAN (HEW), which is known as 6th Generation Wi-Fi (Wi-Fi 6) network. HEW uses an up-link OFDMA-based Random Access (UORA) mechanism for channel access in dense multi-user transmissions.

Intelligent hybrid automatic repeat request retransmission for multi‐band Wi‐Fi networks

open access: yesIET Communications, Volume 15, Issue 9, Page 1249-1258, June 2021., 2021
Abstract With the increase of Wi‐Fi connections and throughput, the problems posed by unreliable connection and unstable delay need to be urgently solved through advanced methods. The IEEE 802.11ax standard was designed to improve the reliability of connection and increase the throughput in dense Wi‐Fi scenario where the inter‐site interference becomes

Enabling Device‐to‐Device (D2D) Communication for the Next Generation WLAN

open access: yesWireless Communications and Mobile Computing, Volume 2021, Issue 1, 2021., 2021
Device‐to‐device (D2D) communication technology is widely acknowledged as an emerging candidate to alleviate the wireless traffic explosion problem for the next generation wireless local area network (WLAN) IEEE 802.11ax. In this paper, we integrate D2D communication into IEEE 802.11ax for maximizing the spectrum efficiency.

Group-Based Uplink OFDMA Random Access Algorithm for Next-Generation WLANs

open access: yesXibei Gongye Daxue Xuebao, 2020
The traditional wireless local area network(WLAN) standard, IEEE 802.11, adopts carrier sense multiple access/collision avoidance(CSMA/CA) mechanism to allow a single user to compete for channel access. The upcoming WLAN standard, IEEE 802.11ax, combines

Receiver-Based Flow Control for Networks in Overload [PDF]

open access: yes, 2012
We consider utility maximization in networks where the sources do not employ flow control and may consequently overload the network. In the absence of flow control at the sources, some packets will inevitably have to be dropped when the network is in ...
