PhD Position in Energy-Efficient and Resilient Internet
University of Twente Faculty of Electrical Engineering, Mathematics and Computer Science
Netherlands

Job description

The Internet forms the backbone of today's economy and society. However, the energy consumption of the Internet is getting out of hand: it is projected to consume one fifth of global energy by 2025! This huge energy consumption also makes the Internet vulnerable to failures of its energy resources, for example due to low solar panel productions.

Therefore, our goal in this collaborative project between Computer Science, Mathematics and Integrated Circuit Design (Electrical Engineering) is to make the Internet energy-efficient and resilient towards energy failures.

Project descriptions

We are looking for three PhD students in this interdisciplinary project who will work on one of the following related topics:

PhD 1 (Computer Science)

Focus is on the energy efficiency of wireless access networks, particularly WiFi and 5G. You will design and develop resource allocation algorithms for WiFi/5G networks to ensure high energy efficiency by finding the best operation parameters such as frequency, bandwidth, and antenna configurations. While the underlying hardware, so-called software-defined radios, facilitate this flexible operation by tuning various parameters of a wireless device, these different operation settings will lead to different energy consumption and latency figures that must be considered in resource allocation. You will investigate how to use the state-of-the-art networking paradigms and protocols to decrease the energy footprint of wireless access networks.

This PhD is part of the Design and Analysis of Communication Systems (DACS) group and supervised by dr. Suzan Bayhan and prof. Geert Heijenk.

PhD 2 (Mathematics)

Focus is on how the structure of the internet network and its energy supply affects internet outages. Different types of internet links (wireless/wired) and energy sources react differently to failures. Therefore, you will first create realistic mathematical models of 5G and its energy supply that take this into account, using random graph models. You will then investigate how this model reacts to probabilistic energy failures: what happens when some energy resources break down with some probability? Finally, you will investigate how to make 5G more robust against energy shortages. For example, can we predict which part of the internet will break down when an energy resource fails? And can we use optimization to find alternative paths for wireless signals to prevent these internet outages?

This PhD is part of the Mathematics of Operations Research group, and supervised by dr. Clara Stegehuis and prof. Nelly Litvak.

PhD 3 (Integrated Circuit Design)

This PhD student would work towards circuit and system level development of low power solutions in a fully programmable Software Defined Radio application for mainstream communication devices such as in WiFi and 5G. Various building blocks such as filters, mixers, N-path circuits would be optimized from the perspective of power consumption with an aim for achieving programmability. We have access to advanced CMOS fabrication technology nodes for realizing the design solutions envisaged in this project to actual test-chip prototype and a well-equipped laboratory for evaluation of the test-chips.

This PhD student will be based at the Integrated Circuit Design Group, chaired by Prof. Bram Nauta
