Improving Efficiency of Heterogeneous Wi-Fi Networks with Energy-Limited Devices
P. 181–192.
A heterogeneous wireless network consists of various devices that generate different types of traffic with heterogeneous requirements for bandwidth, maximal delay and energy consumption. An example of such networks is a Wi-Fi HaLow network that serves a big number of Machine Type Communication battery-powered devices and several offloading client stations. The first type of devices requires an energy-efficient data transmission protocol, while the second one demands high throughput. In this paper, we consider a mechanism that allocates a special time interval (Protected Interval) inside of which only battery powered-powered devices can transmit. We show that appropriate selection of the Protected Interval duration allows battery-powered devices to consume almost the minimal possible amount of energy on the one hand, and to provide almost the maximal throughput for offloading stations on the other hand. To find such duration, we develop a mathematical model of data transmission in a heterogeneous Wi-Fi network.

Decreasing energy consumption of devices is an important problem for modern Wi-Fi networks. To address this problem, the very first version of the Wi-Fi standard introduced a basic power saving mechanism. At the same time, the new IEEE 802.11ax and IEEE 802.11ba amendments describe modern power save mechanisms: target wake time (TWT) and wake-up radio ...

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 ...
