  • Important: don’t forget to mention in your application how you found out about the position.

Host: Mälardalen University College (MDH), School of Innovation, Design and Engineering.

  • Main supervisor: Assoc. Prof. Elisabeth Uhlemann, elisabeth.uhlemann@mdh.se (contact person)
  • Co-supervisor: Prof. Mats Björkman, mats.bjorkman@mdh.se


  • Mandatory requirements for all PhD positions
  • The applicant is required to have a Master or equivalent degree with a solid documented background in communications, embedded systems, computer science or electrical engineering. Additional knowledge in the fields of mobile wireless networks and industrial automation systems is a plus. A good level of English is a requirement as the studies are performed in English.


  1. Enable deterministic wireless access to Fog Computing Nodes and between layers of Fog Nodes
  2. Design, develop and analyze deterministic wireless protocols for industrial automation, in mobile scenarios with frequently changing network topologies

Expected Results:

  • Communication protocols able to send short packets over wireless channels in order to obtain ultra-reliable, predictable and low-latency communication even in mobile scenarios.
  • Designing a medium access method capable of providing predictable access delay for applications with diverse requirements, using different types of cooperative diversity techniques to provide sufficient reliability before a given real-time deadline.
  • Relaying strategies aiming to achieve full diversity also in mobile scenarios; depending on the specific use-case unicast of broadcast relaying are to be considered, where either a relay selection or a relay assignment strategy is developed.
  • Evaluation of the performance for the proposed protocols.

Planned visits and collaboration:

  • TTTech (Dr. Wilfried Steiner): Integrate wireless protocols into the Fog Node
  • Danish Technological Institute (Dr. Lars Dalgaard): Evaluate the wireless protocols on a mobile robots use case.
