Future real-time and remotely-controlled human-to-machine (H2M) applications such as teleoperation and telemedicine will need to be supported by communication infrastructures that incur very low and stringent end-to-end communication latency of approximately 1 to 10 ms. Addressing this latency challenge through novel AI-assisted resource allocation strategies necessitates a deep understanding of H2M traffic. The main challenge has been the scarcity of real H2M traffic traces, despite the recent interests from both academia and industry. Consequently H2M traffic characteristics/statistics are relatively unknown.  This project aims to establish experiments that emulate H2M applications and to develop analytical models for H2M traffic.  The key outcome is a deep understanding of the characteristics of H2M traffic and hence its latency and reliability requirements. 

This project is presently recruiting PhD candidate(s) with a background in Electrical and Electronic Engineering and/or Computer Science. Interested candidates with a keen interest in experimental investigation and analytical modelling, are encouraged to contact Prof. Wong. The successful candidate(s) will be mentored by a team of leading experts with pioneering contributions in broadband access networks, converged fibre-wireless networks, human-to-machine communication networks, Internet-of-Things, optical wireless networks, and the Tactile Internet.
