LZn : Robust LoRa Frame Synchronization Under Frame Collisions and Ultra-Low SNR Conditions
José Álamos, Thomas C. Schmidt, Matthias Wählisch
LoRa has become a widely adopted wireless modulation scheme in LPWANs due to its low cost, long range, and minimal transmission power. However, collisions between frames of the sam…
Adaptive Learning Mechanisms for Learning Management Systems: A Scoping Review and Practical Considerations
Sebastian Kucharski, Iris Braun, Gregor Damnik +1
Background: Traditional Learning Management Systems (LMSs) usually offer one-size-fits-all solutions that cannot be customized to meet specific learner needs. To address this issue…
Duty-Cycling is Not Enough in Constrained IoT Networking: Revealing the Energy Savings of Dynamic Clock Scaling
Michel Rottleuthner, Thomas C. Schmidt, Matthias Wählisch
Minimizing energy consumption of low-power wireless nodes is a persistent challenge from the constrained Internet of Things (IoT). In this paper, we start from the observation that…
Combating the Effects of Cyber-Psychosis: Using Object Security to Facilitate Critical Thinking
Robert H. Thomson, Quan Nguyen, Essien Ayanam +4
Humanity is currently facing an existential crisis about the nature of truth and reality driven by the availability of information online which overloads and overwhelms our cogniti…
CoRa: A Collision-Resistant LoRa Symbol Detector of Low Complexity
José Álamos, Thomas C. Schmidt, Matthias Wählisch
Long range communication with LoRa has become popular as it avoids the complexity of multi-hop communication at low cost and low energy consumption. LoRa is openly accessible, but…
A Call to Reconsider Certification Authority Authorization (CAA)
Pouyan Fotouhi Tehrani, Raphael Hiesgen, Thomas C. Schmidt +1
Certification Authority Authentication (CAA) is a safeguard against illegitimate certificate issuance. We show how shortcomings in CAA concepts and operational aspects undermine it…
