6G Networks: Improving resiliency for human-to-machine (H2M) applications

Project Leader: Elaine Wong
Collaborators: Prof Lena Wosinska (Chalmers University of Technology), Prof Carmen Mas Machuca (Technical University of Munich)

Disciplines: Electrical & Electronic Engineering

Future 6G communication networks are expected to support mission-critical human-to-machine (H2M) applications, eg, tele-surgery and coordinated driving, that require a 99.999% network reliability. This is equivalent to at most 0.86 seconds of downtime per day. The future-proofing of existing communication networks to rapidly detect failures and to support H2M traffic with minimal disruption, has yet to be critically investigated.

The primary goals of the project are to design, characterise, and implement fast-responding fault detection techniques and resilient network architectures that meet a network reliability ranging from 99.9% (only 86 seconds of downtime/day) to 99.999% (only 0.86 seconds of downtime/day), depending on the H2M application supported. The performance of these resilient networks are to be evaluated through connection availability and failure-impact-factor measures, with the focus on serving and protecting networks of real cities and towns. Optimal placement of control servers, cloudlets, redundant components and network paths encompassing optical transport, optical x-haul, radio access network through to indoor wireless access networks, to meet reliability and latency demands of different H2M applications, are also to be investigated.

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. Successful candidate(s) will be mentored by a team of leading experts with pioneering contributions in survivable communication network design and protection switching, converged fibre-wireless networks, Internet-of-Things, and the Tactile Internet.
