We are happy to share that our colleague Maximilian Schuh recently attended the prestigious ACM SenSys 2024 conference, a flagship event in the field of networked sensing systems, where he had the honor to present our paper entitled "Understanding Concurrent Transmissions over Ultra-Wideband Complex Channels".

The research presented in this paper, conducted in cooperation with the Technology Innovation Institute, focuses on characterizing and improving the performance of concurrent transmissions over ultra-wideband (UWB) complex channels, which were previously known to be unreliable. The paper's results unlock solutions to the growing scarcity of available UWB channels and pave the way for highly-scalable UWB systems.

Max and his colleagues have conducted a large-scale experimental campaign to explore the root causes of packet loss during concurrent transmissions across different complex channels. Their findings highlight methods to significantly improve reliability (i.e., sustaining more than eight concurrent UWB transmissions on the same frequencies with a packet reception rate above 99%) while preserving the excellent ranging capabilities that make UWB technology so promising.

Congratulations to Max and his colleagues for this remarkable contribution to advancing UWB technology and for representing our institute on such an important global stage!

November 2024

Our colleague Theo Gasteiger recently traveled to Washington, D.C., to represent our research group at the prestigious IEEE MILCOM 2024 conference.

This innovative work introduces a lightweight security mechanism for Bluetooth LE Audio systems by adapting the TESLA protocol to Broadcast Isochronous Streams (BIS). It effectively addresses critical vulnerabilities, such as the BISON attack, which our research team previously uncovered and demonstrated.

We are excited to see further research developments in shaping the future of Bluetooth security, particularly in the realm of LE Audio.

Hannah Brunner visited the CPS-IoT Week in Hong Kong to present her paper "Simba: A Unified Framework to Explore and Facilitate the Design of Battery-Free Systems" at the International Conference on Information Processing in Sensor Networks (IPSN).

There, she won the Best Artifact Award for the Simba framework, which is open-source on GitHub. Congratulations Hannah!  

The Simba framework helps with designing battery-free systems: these are small sensing devices that operate on harvested energy (e.g., from the sun or radio-frequency signals) and have a minimal energy budget, which makes their design rather difficult. Simba supports the designers of battery-free systems in exploring different design trade-offs in a fast and easy way based on simulation.

The work was carried out in collaboration with researchers at TU Delft, where Hannah also completed a two-week research stay in June 2023.

Both works highlight some fundamental problems prevalent in the design of RTOS kernels.

The first paper addresses the issues associated with empty activations of sequencer tasks in "Avoiding Empty Instances and Offset Drifts of Basic Sequencer Tasks in Automotive Operating System."  The second work addressed a critical issue in multicore synchronization with spinlocks in "Fair and Starvation-Free Spinlock for Real-Time AUTOSAR Systems." Both works were well received, and our colleagues could gather valuable feedback for future work on designing RTOS kernels.

April 2024

We are excited to share that FazyRV, a scalable minimal-area RISC-V core, is now open source under a permissive MIT license. The work will be presented at the Computing Frontiers 2024 conference by Meinhard Kissich and Prof. Marcel Baunach.
