Beacon-Based Wireless TSN Association

Abstract

Time-sensitive networking (TSN) is utilized in industrial environments to support reliable low-latency communications. Bringing TSN features to wireless networks is getting traction recently by achieving time synchronization and traffic scheduling over wireless links. Besides these basic features, impact-less and network transparent association of prospective clients is paramount for wireless TSN. This demo presents an impactless TSN association procedure, where beacons are used to provide time synchronization and scheduling to prospective clients, where association procedure is done in reserved time slots. The presented demo is designed, implemented, and tested on top of a wireless Software Defined Radio platform using the IEEE802.11 standard. By utilizing a dashboard, this demo will demonstrate real-time control over association as well as high accuracy synchronization on client frame transmissions even with challenging scheduling configuration of 128 µS timeslots.

Unlocking Mobility for Wi-Fi-Based Wireless Time-Sensitive Networks

“…1) In order to mitigate undesired UL transmissions throughout the procedure, the STA will enact a transmission gating system and systematically queue frames. While a comprehensive elucidation of the gating system is beyond the scope of this paper, a detailed exposition can be referenced in [12].…”

“…By using our W-TSN evaluation kit, built on top of the open-source platform openwifi [9], we addressed various wireless challenges specifically related with Wi-Fibased TSN, including management [10], association [11], application-network integration [12], and mobility with the present work. Within wireless networks, one of the fundamental factors enabling mobility is handover.…”
