Abstract: Emerging applications are demanding more than high throughput and average low latency from wireless networks. A growing number of time-critical applications, such as mobile robots, autonomous vehicles, industrial automation, real-time analytics, mobile gaming and AR/VR, need worst-case low latency guarantees and extremely high reliability. Given the inherently unreliable, varying capacity and latency prone characteristics associated with wireless communications, enabling “time-critical” performance is major challenge, but it is also opportunity for next generation wireless technologies. This talk will provide an overview of emerging applications, requirements and unique challenges to enable time-critical performance over wireless. The presentation will review the background work by the IEEE 802.1 Time Sensitive Networking (TSN) family of standards, dive into existing and upcoming features extending TSN capabilities over Wi-Fi/802.11 (802.11ax/Wi-Fi6) and 5G URLLC standards. The presentation will also highlight implementation challenges that need to be considered beyond standards development, such as interference management, network configuration, cross- device coordination, latency-reliability optimized scheduling, and co-design of time-critical applications and networks. The presentation will conclude with an outlook on evaluation methodologies, tools and testbeds required for validation of wireless technologies and industry adoption for time-critical applications.

Dave Cavalcanti received his PhD in computer science and engineering in 2006 from the University of Cincinnati. He is currently Sr. Research Scientist at Intel Labs where he develops next generation wireless connectivity and networking technologies and their applications in autonomous, time-sensitive systems. Before joining Intel Corporation in 2015, he was with Philips Research North America, where he developed several WLAN, WPAN and cognitive radio technologies. He has contributed to IEEE 802.11 and 802.22 working groups. He is Senior Member of the IEEE and served as the chair of the IEEE computer society technical committee on simulation (TCSIM) from 2008 to 2014. He leads a team who received the IEEE INFOCOM 2018 Best Demo Award for a demonstration of time-critical applications over next generation 802.11 networks.
