Poster: fast and reliable alert delivery in Wi-Fi HaLow sensor networks

P. 1–2.

Khorov E., Lyakhov A., Nasedkin I., Yusupov R.

Rapidly evolving, the Internet of Things poses new challenges for the developers of wireless networks. Various industrial automation, agriculture monitoring, and smart cities scenarios require fast and reliable alert delivery. In many systems, multiple sensors are entrusted to react to the same emergency event. Thus it is enough to receive an alert message from any of these sensors. However, such a message shall be reliably delivered as soon as possible. Recently published Wi-Fi HaLow standard defines the Restricted Access Window (RAW) mechanism that coordinates transmissions of numerous devices and thus can improve reliability and reduce delay. The paper proposes an approach for alert delivery with RAW and investigates how to select optimal RAW parameters, i.e. those parameters that minimize channel time consumption while providing satisfactory reliability and delay for the alert delivery.

Two-Slot Based Model of the IEEE 802.11ah Restricted Access Window with Enabled Transmissions Crossing Slot Boundaries

Khorov E., Lyakhov A., Yusupov R., , in: 2018 IEEE 19th International Symposium on "A World of Wireless, Mobile and Multimedia Networks" (WoWMoM).: IEEE, 2018. P. 1–9.

Recently appeared the IEEE 802.11ah standard has introduced a new channel access mechanism, so-called Restricted Access Window (RAW). This mechanism allows an access point (AP) to reduce contention for the channel in overloaded Wi-Fi networks by limiting the number of stations simultaneously accessing the channel. The 802.11ah AP divides all associated stations into groups and ...

Analytical Study of Periodic Restricted Access Window Mechanism for Short Slots

Zazhigina E., Yusupov R., Khorov E. et al., Electronics (MDPI) 2021 Vol. 10 No. 5 Article 549

The tremendous number of devices involved in the Internet of Things is bringing new challenges to wireless networking. The more devices that transmit in a wireless network, the higher the contention for the channel. The novel Wi-Fi HaLow standard introduces a new channel access mechanism called the Periodic Restricted Access Window (PRAW), which aims to ...

Enabling the Internet of Things With Wi-Fi Halow—Performance Evaluation of the Restricted Access Window

Khorov E., Krotov A., Lyakhov A. et al., IEEE Access 2019 Vol. 7 P. 127402–127415

IEEE 802.11ah, a new amendment to the Wi-Fi standard, adapts Wi-Fi networks to the emerging Internet of Things (IoT). A key component of .11ah is the Restricted Access Window (RAW), a new channel access mechanism, which reduces contention when even thousands of IoT devices operate in the same area by assigning them different channel times. ...

What Is the Fastest Way to Connect Stations to a Wi-Fi HaLow Network?

Bankov D., Khorov E., Lyakhov A. et al., Sensors 2018 Vol. 18 No. 9 P. 1–18

Wi-Fi HaLow is an adaptation of the widespread Wi-Fi technology for the Internet of Things scenarios. Such scenarios often involve numerous wireless stations connected to a shared channel, and contention for the channel significantly affects the performance in such networks. Wi-Fi HaLow contains numerous solutions aimed at handling the contention between stations, two of which, ...
