Experimental Interference Robustness Evaluation of IEEE 802.15.4-2015 OQPSK-DSSS and SUN-OFDM Physical Layers
Pere Tuset-Peiró, Francisco Vázquez-Gallego, Jonathan Muñoz +3
In this paper, we experimentally evaluate and compare the robustness against interference of the OQPSK-DSSS (Offset Quadrature Phase Shift Keying - Direct Sequence Spread Spectrum)…
Experimental Clock Calibration\\on a Crystal-Free Mote-on-a-Chip
Ioana Suciu, Filip Maksimovic, David Burnett +6
The elimination of the off-chip frequency reference, typically a crystal oscillator, would bring important benefits in terms of size, price and energy efficiency to IEEE802.15.4 co…
Authenticated Preambles for Denial of Service Mitigation in LPWANs
Ioana Suciu, Jose Carlos Pacho, Andrea Bartoli +1
In this article we introduce authentication preambles as a mechanism to mitigate battery exhaustion attacks in LPWAN networks. We focus on the LoRaWAN technology as an exponent of…
A Channel Measurement Campaign for mmWave Communication in Industrial Settings
Adrian Loch, Cristina Cano, Gek Hong +3
Industry 4.0 relies heavily on wireless technologies. Energy efficiency and device cost have played a significant role in the initial design of such wireless systems for industry a…
Aggressive Fragmentation Strategy for Enhanced Network Performance in Dense LPWANs
Ioana Suciu, Xavier Vilajosana, Ferran Adelantado
Low Power Wide Area Networks (LPWANs) are gaining ground in the IoT landscape and, in particular, for Industrial IoT applications. However, given the strict duty cycle restrictions…
