The specific focus of this PhD research project is on integration of non-terrestrial networks (NTN) (aka satellite communication networks) with terrestrial networks (TN) (5G/6G mobile networks). The high level of industry investment in the past decade in low-earth orbit (LEO) satellite systems has formed mega satellite constellations, which can offer satellite communication capabilities with high data rates across the globe. Integrating LEO constellations with terrestrial 5G/6G networks has great potential for the betterment of the society by providing true global network coverage to people and businesses.
This research work will tackle a set of technical challenges that the communication systems industry is facing today. The capabilities of modern artificial intelligence (AI) and machine learning (ML) techniques have high potential in addressing these challenges towards effective NTN-TN integrations.
As a PhD student, you will specifically study the use of "AI agents" that can self-govern their respective domains of responsibility in an integrated networking system. The AI agents will receive performance and status metrics from the network, employ learning algorithms, and take actions to manage network control via software-defined networking (SDN) APIs. By means of forming a collaborative multi-agent environment, the system will dynamically modify packet routing policies for reliable content delivery and uninterrupted communication sessions in an integrated satellite and mobile network setting.
The output from this research will make significant contributions to University of Surrey's substantial efforts to further strengthen its leadership in satellite communications. The student will have access to the world-class test bed research facilities offered by Surrey’s flagship research institutes: Institute for Communication Systems (ICS) and Surrey Space Institute (SSI). The student will also have the opportunity to work with partner organisations in the industry and deploy their solutions in ICS’s 6G data centre for experimental evaluations.
Supervisors: Dr Serdar Vural and Professor Rahim Tafazolli
Entry requirements
Open to candidates who pay UK/home rate fees. See UKCISA for further information. Starting in October 2026. Later start dates may be possible, please contact Dr Serdar Vural once the deadline passes.
You will need to meet the minimum entry requirements for our PhD programme.
The ideal PhD candidate will be highly motivated with a strong interest in software development for telecommunication networks and a research‑engineering mindset. A solid background in computer networks and programming (preferably Python and/or Go) is required, with experience from coursework, projects, or hackathons valued. Knowledge of SDN, AI/ML, cloud technologies (e.g. Kubernetes, Docker), and Git‑based development is desirable, with AI/ML experience particularly relevant. The candidate should have an interest in mathematical modelling, network protocols, and systems design, alongside strong technical writing and communication skills to support publication and collaboration with ICS and SSI teams.
How to apply
