PhD Thesis: Methodology for implementation of Synchronization Strategies for Wireless Sensor Networks

On July 16, 2020, our colleague Francisco Tirado-Andrés read and defended his PhD Thesis entitled “Methodology for implementation of Synchronization Strategies for Wireless Sensor Networks” under the direction of Dr. Alvaro Araujo Pinto.

This work was defended in an unusual way. Half of the tribunal was in person, but the other half of the tribunal was evaluating it via video conference. Even with this new form of presentation, the Thesis work was valued very positively by the entire tribunal, giving it the highest score: outstanding.
In addition, the entire tribunal issued a confidential and secret vote, which unanimously allowed the work to be awarded the mention of “cum laude”.

Research visit at UC Berkeley

Our lab member Alba Rozas has recently completed a PhD research visit at the Berkeley Wireless Research Center (BWRC), part of the University of California at Berkeley, under the supervision of renowned Profesor Jan Rabaey. This group carries out world-leading research in the fields of radio communications and wireless electronics, with a particular recent interest in Body Area Networks and the Human Intranet.

The main research line of Alba’s PhD is focused on QoS-aware and energy efficient routing strategies for WSNs. This 5-month stay took place within the last stage of her PhD, and its main goal was the study and research of over-the-body communication aspects and the Human Intranet paradigm. These fields have unique characteristics that differentiate them from traditional WSNs, presenting new challenges and opportunities. Thus, in this research stay, Alba has focused on applying the core ideas of her PhD to the field of body area networks. As a result of the work carried out during the visit, she has ultimately developed an energy-efficient and QoS-aware strategy for on-body wireless communication, based on dynamic human activity detection.

In addition to this main research objective, the stay has also strengthened the already existing working relationship between BWRC and B105. Both labs are already collaborating in the development of health-related solutions and systems, initiated by Alvaro Araujo‘s two research visits at BWRC.
