Job Description

One fully funded, full-time PhD position to work with in the at the School of Informatics, University of Edinburgh.
The broad aim of this project is on a holistic investigation of energy efficiency in next-generation mobile networking systems. In the past decade, on the road to 5G, there has been a transformation in the mobile networking infrastructure. For reduced (CapEx) costs, greater flexibility and faster evolution, mobile core/radio network functions today are largely realised in software over commodity computing hardware in private/public cloud data centres. However, this can come at the cost of performance and slower function processing, which manifests as higher energy consumption and increased operational costs (OpEx) for operators. So, a key focus of this project is on reducing energy consumption contributed by running mobile radio/core network functions in a telecom operator's virtualised infrastructure (data centre) by leveraging hardware/software accelerators and through energy-aware workload placement. The project overall will involve cutting-edge research towards holistic optimisation of energy efficiency in mobile networks by tackling the above challenges with novel system designs and tailored AI/ML based methods.
