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…
Jam-X: Wireless Agreement under Interference
Carlo Alberto Boano, Kay Römer, Marco Antonio Zúñiga +1
Wireless low-power transceivers used in sensor networks such as IEEE 802.15.4 typically operate in unlicensed frequency bands that are subject to external interference from devices…
