The rapid evolution of communication networks, which are expected to further grow in complexity and scale, has significantly improved global connectivity. However, this growth also led to a substantial increase in energy consumption, contributing to global carbon emissions and raising environmental concerns.
As networks expand, the processes involved in data transmission require increasingly complex computations, resulting in higher energy usage. For example, routing protocols like the Border Gateway Protocol (BGP) make routing decisions based on the fastest and most reliable network paths. However, this focus on performance raises the question of whether these paths are also sustainable. Similarly, modern security measures to protect against network attacks, often implemented in the cloud, require additional transmission and computational resources. It is questionable whether the energy cost of this additional processing justifies the enhanced security or whether more sustainable alternatives exist.
The goal of this project is to identify and quantify sustainability metrics of networking processes. This includes developing methods to assess the environmental impact of various components, such as routing protocols, measurement techniques, and security mechanisms. Additionally, the project aims to propose innovative solutions that balance the need for high-performance, secure communication with the imperative of reducing the carbon footprint of modern networks.
The candidate will work at the Design and Analysis of Communication Systems DACS-group at the University of Twente. The research will be conducted under the supervision of Dr. Antonia Affinito, Prof. dr. Anna Sperotto and Prof. dr. ir. Geert Heijenk.

About the organisation
The faculty of Electrical Engineering, Mathematics and Computer Science (EEMCS) uses mathematics, electronics and computer technology to contribute to the development of Information and Communication Technology (ICT). With ICT present in almost every device and product we use nowadays, we embrace our role as contributors to a broad range of societal activities and as pioneers of tomorrow's digital society. As part of a people-first tech university that aims to shape society, individuals and connections, our faculty works together intensively with industrial partners and researchers in the Netherlands and abroad, and conducts extensive research for external commissioning parties and funders. Our research has a high profile both in the Netherlands and internationally. It has been accommodated in three multidisciplinary UT research institutes: Mesa+ Institute, TechMed Centre and Digital Society Institute.
