Course description

This lecture will introduce concepts of computer networking related to Internet of Things devices. The goal of the course is to make you feel comfortable designing and secure IoT-based Internet communication. The course gives you an understanding of

  • The hardware used in IoT devices,
  • Embedded software development,
  • Local communication to sensors and actuators,
  • Internet protocols specifically designed for IoT devices,
  • Protocols to manage the lifecycle of IoT devices,
  • Security technologies used on constrained device, and
  • Data protection and privacy.

There will be exercises and it is mandatory to complete all the exercises to attend the final exam. Each student will be provided with IoT hardware. For software development the preferred tool is a professional IDE developed by Keil.


Due to the recent recommendations in the context of Covid-19, we have to defer the start of the lectures of the course on advanced Computer Networks (ACN) to 21.04. 2020. Currently, this course is scheduled in a purely online, non-face-to-face way. We plan to use some tools and platforms, e.g., zoom or DFNconf. Please register into studIP in advance. The registration deadline is at 23:59 pm on 20.04.2020. I will announce which tool will be used before our lectures start. Please contact me by email: if you have any questions.

If you have registered in StudIP, please join our mailing list through ( We will use the mailing list to distribute some documents.
