A Low-Complexity LoRa Synchronization Algorithm Robust to Sampling Time Offsets

Orion Afisiadis, Mathieu Pierre Xhonneux

LoRaWAN is nowadays one of the most popular protocols for low-power Internet of Things communications. Although its physical layer, namely LoRa, has been thoroughly studied in the literature, aspects related to the synchronization of LoRa receivers have re ...

Reliable and Robust Cyber-Physical Systems for Real-Time Control of Electric Grids

Wajeb Saab

Real-time control of electric grids is a novel approach to handling the increasing penetration of distributed and volatile energy generation brought about by renewables. Such control occurs in cyber-physical systems (CPSs), in which software agents maintai ...

iPRP - the Parallel Redundancy Protocol for IP Networks: Protocol Design and Operation

Jean-Yves Le Boudec, Dan-Cristian Tomozei, Miroslav Popovic

Reliable packet delivery within stringent delay-constraints is of paramount importance to mission-critical computer applications with hard real-time constraints. Because retransmission and coding techniques counteract the delay requirements, reliability ma ...

Design and Characterization of a Full-Duplex Multiantenna System for WiFi Networks

Vaneet Aggarwal

In this paper, we present an experiment-and simulation-based study to evaluate the use of full duplex (FD) as a potential mode in practical IEEE 802.11 networks. To enable the study, we designed a 20-MHz multiantenna orthogonal frequency-division-multiplex ...

Fairness of MAC protocols: IEEE 1901 vs. 802.11

Patrick Thiran, Julien Pierre Sacha Herzen, Christina Vlachou

The MAC layer of the IEEE 1901 standard for power line communications employs a CSMA/CA method similar to, but more complex than, this of IEEE 802.11 for wireless communications. The differences between these protocols raise questions such as which one per ...

Palladium-Catalyzed Decarboxylative Vinylation of Potassium Nitrophenyl Acetate: Application to the Total Synthesis of (±)-Goniomitine

Qian Wang, Jieping Zhu, Zhengren Xu

Merge and divert. (±)-goniomitine was synthesized featuring two key steps: a) fragment coupling to functionalized cyclopentene by a novel palladium-catalyzed decarboxylative vinylation reaction and b) an unprecedented one-pot integrated oxidation/reduction ...

Wiley-Blackwell2013

Critical infrastructures are receiving a great deal of attention, due, on the one hand, to the major malfunctions to which they are subject and their potential as targets of malicious intent on the other. Economic and political impacts are studied; increas ...
