“…Sudhakran et al build on top of this work and present a methodology to map application layer timing requirements in a collaborative robot application to the link layer, based on wireless TSN over WiFi [84]. Rather than going further into the TSN standards, they address how to classify traffic, extract time-critical flow parameters, and define an efficient schedule for the end-to-end QoS approach.…”

With the growing need for automation and the ongoing merge of OT and IT, industrial networks have to transport a high amount of heterogeneous data with mixed criticality such as control traffic, sensor data, and configuration messages. Current advances in IT technologies furthermore enable a new set of automation scenarios under the roof of Industry 4.0 and IIoT where industrial networks now have to meet new requirements in flexibility and reliability. The necessary real-time guarantees will place significant demands on the networks. In this paper, we identify IIoT use cases and infer real-time requirements along several axes before bridging the gap between real-time network technologies and the identified scenarios. We review real-time networking technologies and present peer-reviewed works from the past 5 years for industrial environments. We investigate how these can be applied to controllers, systems, and embedded devices. Finally, we discuss open challenges for real-time communication technologies to enable the identified scenarios. The review shows academic interest in the field of real-time communication technologies but also highlights a lack of a fixed set of standards important for trust in safety and reliability, especially where wireless technologies are concerned.

“…Similarly to the previous reference TSN and DDS run in parallel, but independently. In [67], authors explore the capabilities in terms of QoS of wireless TSN networks when combined with DDS. In such work, the intersection between TSN and DDS is introduced by mapping DDS topics to TSN streams.…”

The increasing growth in complexity of vehicles' functionalities is driving a technological shift in the design of software architectures in the automotive industry. Traditional signal-oriented networking is being replaced by service-oriented communications enabled by a new generation of Electronic Control Units (ECUs). The growing interest for full-fledged middlewares can be supported by these powerful ECUs. However, the new capabilities come at a non-negligible cost, which conflicts with the need to design a costeffective solution that allows for meeting aggressive budget goals in a high volume market like automotive. In this paper, we illustrate how a significant part of the functionalities of a powerful middleware like Data Distribution Service (DDS) can be effectively implemented through hardware accelerators. We show that our approach can guarantee high performance while minimizing system complexity at the software level (e.g. AUTOSAR) by shifting painful or inefficient software implementations of QoS policies directly to hardware. This, in turn, allows to build cost-effective solutions suitable for next-generation automotive systems.

“…Further exploration regarding this approach is detailed in Section II. [17] uses TM frames based 802.1AS for CS over Intel Wi-Fi 5 cards in Collaborative Robotics applications. Though this work focuses on combining robotic operating system with wireless TSN traffic flow to maintain optimal network jitter and latency, it never quantified CS performance directly, and neither exposed any information regarding how 802.1AS is realized over Wi-Fi TM.…”

Precision Time Protocol (PTP), a state-of-the-art clock synchronization protocol primarily designed for wired networks, has recently gained attention in the wireless community, due to the increased use of IEEE 802.11 Wireless Local Area Networks (WLAN) in real time distributed systems. However, all the existing WLAN based PTP designs either incorporate software Timestamping (TS) delivering poor clock synchronization accuracy, or Hardware (HW) TS providing better synchronization accuracy at the cost of a significant amount of HW overhead. Moreover, the performance of the existing PTP solutions is mostly evaluated in single-hop wireless networks, while the performance across wired and wireless networks is taken for granted. In this paper, a new Software Defined Radio (SDR) based approach to implement PTP is introduced and validated for IEEE 802.11 WLAN. Instead of using a dedicated HW clock, the solution utilizes the Timing Synchronization Function (TSF) clock, an existing clock in IEEE802.11 standard for synchronization between access point and WLAN stations. The performance of the proposed solution is first investigated within a single-hop WLAN and then across wired-wireless networks. Experimental results unveil that 90% of the absolute clock synchronization error falls within 1.4 µs.
