Through advances in sensor, networking, semiconductor and energy storage technologies, Wireless Sensor Networks (WSNs) are increasingly being deployed in many important applications to enable users to ...
Barrachina Muñoz, Sergio (Date of defense: 2021-01-19)
In this thesis, we focus on the so-called spectrum management's joint problem: efficient allocation of primary and secondary channels in channel bonding wireless local area networks (WLANs). From IEEE ...
Cano Bastidas, Cristina (Date of defense: 2011-03-04)
In the last few years Wireless Sensor Networks (WSNs) have become an interesting field of research mainly due to the challenges and constraints of their design and the broad range of potential applications ...
Wilhelmi Roca, Francesc (Date of defense: 2020-10-07)
The Spatial Reuse (SR) operation is gaining momentum in the latest IEEE 802.11 family of standards due to the overwhelming requirements posed by next-generation wireless networks. In particular, the ...
