Robust Generalization of Graph Neural Networks for Carrier Scheduling
Daniel F. Perez-Ramirez, Carlos Pérez-Penichet, Nicolas Tsiftes +3
Battery-free sensor tags are devices that leverage backscatter techniques to communicate with standard IoT devices, thereby augmenting a network's sensing capabilities in a scalabl…
Application-aware Energy Attack Mitigation in the Battery-less Internet of Things
Chetna Singhal, Thiemo Voigt, Luca Mottola
We study how to mitigate the effects of energy attacks in the batteryless Internet of Things (IoT). Battery-less IoT devices live and die with ambient energy, as they use energy ha…
Timing Analysis of Embedded Software Updates
Ahmed El Yaacoub, Luca Mottola, Thiemo Voigt +1
We present RETA (Relative Timing Analysis), a differential timing analysis technique to verify the impact of an update on the execution time of embedded software. Timing analysis i…
Uncharted Territory: Energy Attacks in the Battery-less Internet of Things
Luca Mottola, Arslan Hameed, Thiemo Voigt
We study how ambient energy harvesting may be used as an attack vector in the battery-less Internet of Things (IoT). Battery-less IoT devices rely on ambient energy harvesting and…
An Experimental Study of Byzantine-Robust Aggregation Schemes in Federated Learning

We present a new machine learning-based attack that exploits network patterns to detect the presence of smart IoT devices and running services in the WiFi radio spectrum. We perfor…
TunnelScatter: Low Power Communication for Sensor Tags using Tunnel Diodes
Ambuj Varshney, Andreas Soleiman, Thiemo Voigt
Due to extremely low power consumption, backscatter has become the transmission mechanism of choice for battery-free devices that operate on harvested energy. However, a limitation…
Visible Light Communication for Wearable Computing
Ambuj Varshney, Luca Mottola, Thiemo Voigt
Visible Light Communication (VLC) is emerging as a means to network computing devices that ameliorates many hurdles of radio-frequency (RF) communications, for example, the limited…
Five-Nines Reliable Downward Routing in RPL
Simon Duquennoy, Joakim Eriksson, Thiemo Voigt
After a decade of research in low-power data collection, reaching arbitrary nodes has received comparatively little attention. The leading protocol for low-power IPv6 routing, RPL,…
Mitigating Inter-network Interference in LoRa Networks
Thiemo Voigt, Martin Bor, Utz Roedig +1
Long Range (LoRa) is a popular technology used to construct Low-Power Wide-Area Network (LPWAN) networks. Given the popularity of LoRa it is likely that multiple independent LoRa n…
LoRea: A Backscatter Architecture that Achieves a Long Communication Range
Ambuj Varshney, Oliver Harms, Carlos Perez Penichet +3
There is the long-standing assumption that radio communication in the range of hundreds of meters needs to consume mWs of power at the transmitting device. In this paper, we demons…
