About SEtS

This is a Studentship opportunity within the Doctoral Centre for Safe, Ethical and Secure Computing (SEtS) in the Department of Computer Science at the University of York. SEtS is a key initiative which supports our strategic vision to internationally lead education and research in the engineering of safe, ethical and secure computational systems. Find out more about SEtS.

About the Project

Time-Sensitive Network (TSN) standards address time synchronisation, latency bounds, reliability and resource management in local area and metropolitan area networks following IEEE 802 standards for physical and data link layers [1]. Initial use of the TSN standards focused on wired networks (e.g. Ethernet), but recent research and development efforts have also attempted to extend TSN to wireless networks such as WiFi[2] and 5G[3]. The standards aim to fulfil the performance and reliability requirements often found in application domains such as industrial automation, aerospace, automotive, drone, audio, video and robotic systems.  

In this project, you will investigate the application of TSN standards to mixed-criticality traffic on wireless networks. The objective of the work is to achieve performance guarantees to all traffic under normal operation conditions, but to degrade service to less critical traffic when required due to poor wireless channel conditions (e.g. as achieved by the AirTight protocol in IEEE 802.15.4 networks [4]). To achieve that objective, the research will address analytical models supporting the traffic shaping primitives available in the TSN standard, packet scheduling mechanisms that are able to distinguish criticality, and evaluation platforms based on small network prototypes as well as large scale simulation.
