Adaptive Network Coding to Develop Future Networks and Cloud Technologies

Applications are invited for one PhD fellowship/scholarship at Graduate School of Science and Technology, Aarhus University, Denmark, within the Engineering programme. The position is available from 1 May 2018 or later.

Title:
Adaptive Network Coding to Develop Future Networks and Cloud Technologies

Research area and project description:
Future communication networks and storage systems will face tremendous challenges to answer the increasing data traffic generated by end users, the novel requirements of 5G communications, and by the 50 to 500 billion sensor and actuation devices to be connected to the Internet of Things (IoT). Additionally, upcoming services and applications may also impose very low delay constraints on the transferred data. This will naturally prevent us from using current client-server infrastructures or popular cloud services. The main reason is that servers and cloud infrastructure are typically far away from the end-devices themselves, which translates into high delay to reach them. Furthermore, the costs of transferring massive amounts data all the way through the network to reach a cloud are prohibitive with 50 to 500 billion connected devices due to the economic costs in infrastructure capable of servicing these high loads and the energy costs for transferring to and processing at the cloud. Thus, developing technologies that (i) increase the throughput, (ii) reduce the delay, (iii) operate in a distributed fashion, (iv) are economically viable, and (v) store and process data close to the end devices, is crucial to the design and deployment of future communication networks and cloud computing.

This project will focus on revisiting and generalizing theoretical results in network coding and design novel, adaptive network codes, that rely on new finite field constructions that are suited for flexible management of complexity and performance. This work is expected to open a new field in traditional coding theory under the lens of these new finite field constructions. The results and designs from this project will be focused on developing new technologies for Cloud, Fog, and Local content management with an emphasis on IoT data. The student is expected to deploy such designs in practical systems of interest (e.g., using and contributing to OpenSource projects) to demonstrate the results. This project will have interactions with companies and local start-ups as well as participation in IETF events with the potential to generate both theory and designs that address real practical challenges, high impact publications in journals and conferences, and patent filings.

Our goal is to design communication and storage technologies for future cloud and networks using novel coding theory constructions at the core of such designs.

Qualifications and specific competences:
We are looking for highly motivated and independent students willing to take the challenge to do a successful 3-year PhD programme in Aarhus University. The ideal candidate will have the following profile (but not all items are required for a successful application):

  • Relevant Master’s degree (e.g., Electrical Engineering, Computer Engineering, Software Engineering), although exceptional candidates from related disciplines (e.g., Mathematics) will also be considered.
  • Excellent undergraduate and master degree grades are required.
  • Background on communication systems, networking, distributed storage and distributed systems. This is highly desired, but candidates from other disciplines will be considered based on their merits and potential.
  • Background on mathematics, probability, and/or error correcting codes is desired.
  • Background on programming, particularly C++, Java, and/or python, or experience with distributed systems and open source (e.g., OpenStack, OpenCompute) is desired.
  • Knowledge and experience in network coding is desired, but not mandatory.
  • Good English verbal and written skills are a must.

Place of Employment and Place of Work:
The place of employment is Aarhus University, and the place of work is the Department of Engineering, Turing Building (5341), Åbogade 34, 8200 Aarhus N

Application procedures


Before you apply

Information and attachments:

Please be aware that you must have all relevant appendices, attachments, addresses for referees, etc. ready when you apply, as the entire application must be uploaded to the system in one go.

Documentation of language skills:

The English language requirement at Graduates School of Science and Technology is comparable to an “English B level” in the Danish upper secondary school (“gymnasium”).

English language qualifications comparable to an “English B level” is documented by one of the following tests:

  • TOEFL test, minimum score: 560 (paper-based test) or 83 (internet-based test)
  • IELTS (academic) test, minimum average score: 6.5 points
  • Cambridge English Language Assessment:
    Cambridge Certificate of Proficiency (CPE)
    Cambridge English: Certificate of Advanced English with grade A,B or C (CAE)
    Cambridge English: First Certificate  with grade A (FCE)

When to take the test and how to upload the documentation:
The test result must not be more than two years old at the time of application.

The English language test should be taken before applying for admission and uploaded under “language skills documentation” in the online application form.

It is possible to apply for admission before you have taken the test. In this case documentation stating that you have signed up for a test (please state expected submission date) must be uploaded. If the test result is not part of the original application the test result is to be sent to sphd@psys.au.dk no later than one month after the application deadline.

The following applicants are exempted from documenting their English qualifications/taking a test:

  • Applicants with citizenship from the following countries: Australia, Canada, Ireland, New Zealand, United Kingdom, United States, or one of the Nordic countries (Denmark, Finland, Iceland, Norway or Sweden).
  • Applicants with a Bachelor’s or Master’s programme completed in Australia, Canada, Ireland, New Zealand, United Kingdom, or United States. In this case, please upload your Bachelor’s or Master’s diploma under the section ”Language skills documentation”.
  • Applicants with a Bachelor’s or Master’s programme completed at Aarhus University for which the requirement was English B level at the time of admission. In this case, please upload your Bachelor’s or Master’s diploma under the section”Language skills documentation”.
  • Applicants able to document that English was the language of instruction during the whole period of their Bachelor’s and/or Master’s programme. This must be documented by uploading an official document from the institution stating this under “language skills documentation”.

The programme committee may request further information or invite the applicant to attend an interview.
