• October 2021: The 1st Workshop on Testing Distributed Internet of Things Systems (TDIS) has been held (online). We were impressed by the invited talks, paper presentations, and lively discussions.
• September 2021: The program of our 1st Workshop on Testing Distributed Internet of Things Systems (TDIS) is now finalized: We are looking forward to a total of six paper presentations as well as to two invited talks on the first day of IEEE IC2E 2021, October 4, from 8 am PDT / 5 pm CEST. Take a look on the website, under Workshop Program.
• August 2021: Same as last year, we are helping to organize the ide3a winter school program of the upcoming winter term. Registrations are open until September 28!
• April 2021: Our short paper on Marvis won the "Best WiP Paper" award at PerCom 2021.
• March 2021: We are helping to set up a new lecture series in the ide3a network. The lectures on "Critical Infrastructures and Digitalization" will discuss urban infrastructures such as transport systems, energy grids, water networks, and information technology. It will run this summer semester for the first time, with registrations due already on March 26!
• February 2021: We are organizing the 1st International Workshop on Testing Distributed Internet of Things Systems (TDIS) at IEEE IC2E 2021. The workshop scope includes simulations, models, hybrid testbeds, test frameworks, failure injection, monitoring tools, and IoT applications. If your work is related, consider submitting a paper!
• October 2020: We are currently looking for motivated students who want to work with us in their master theses. Get in touch, if you are generally interested in hybrid co-simulation testbeds for IoT applications or, more specifically, auto-calibration of emulated IoT resources!
• August 2020: We are helping to organize the winter school series of ide3a in the upcoming winter term. The first course will take place at TU Berlin from October 5 to 9. The application deadline is September 10.
• June 2020: To further facilitate the ongoing collaboration between the Distributed and Operating Systems group at TU Berlin and the Operating Systems and Middleware group at HPI, we founded the diselab. In the lab, we jointly look at how efficient and dependable distributed IoT systems for critical infrastructures can be developed, tested, and operated.
