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

Abstract

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, namely, the Centralized Authentication Control (CAC) and the Distributed Authentication Control (DAC), address the contention reduction during the link set-up process. The link set-up process is special because the access point knows nothing of the connecting stations and its means of control of these stations are very limited. While DAC is self-adaptive, CAC does require an algorithm to dynamically control its parameters. Being just a framework, the Wi-Fi HaLow standard neither specifies such an algorithm nor recommends which protocol, CAC or DAC, is more suitable in a given situation. In this paper, we solve both issues by developing a novel robust close-to-optimal algorithm for CAC and compare CAC and DAC in a vast set of experiments.

Queries allocation in WSNs with fuzzy control system

“…To reduce the contention time between stations when connecting, the authors of ref. [30] use Wi-Fi HaLow; there are other approaches based on cognitive radio [31], or wake-up radio sensors [32] that exploit hardware features to optimize some QoS criteria, latency, and data age. In this scheme, it is assumed that the request processing at the base station and cache is negligible compared to the processing at the WSN.…”

QoS in Wireless Sensor Networks

“…Reference [ 7 ] focuses on Wi-Fi HaLow, an adaptation of the widespread Wi-Fi technology for the Internet of Things scenario, and, in particular, aims to reduce the contention time between stations when connecting.…”

Bandwidth Cost Minimization via User Association for Enterprise WLANs

“…WiFi has been broadly studied from various aspects, e.g., fast connection [1], indoor localization [2,10]. However, the default association method for a mobile user in 802.11 protocol is not an efficient approach for user-to-AP association as proved in [11], therefore various studies have been performed to properly associate users to APs for different purposes, e.g., to avoid congestion [12], balance the load [4], alleviate interference [13].…”

“…WLANs have been widely deployed in various scenarios from home wireless networks to enterprise networks. Moreover, it could be adapted to Internet-of-Things scenarios [1]. The popularity of smart devices further promotes the wide deployment of WLANs, especially in enterprise networks.…”
