Fernández Fernández, Adriana (Data de defensa: 2018-06-29)
Achieving energy efficiency has recently become a key topic of networking research due to the ever-increasing power consumption and CO2 emissions generated by large data networks. This problem is becoming ...
Henarejos Hernández, Pol (Data de defensa: 2017-07-19)
Radiocommunication systems have evolved significantly in recent years in order to meet present and future demands. Historically, time, frequency and more recently, spatial dimensions have been used to ...
Lagén Morancho, Sandra (Data de defensa: 2016-12-21)
The envisioned rapid and exponential increase of wireless data traffic demand in the next years imposes rethinking current cellular networks due to the available spectrum scarcity. In this regard, 3 ...
Catalán Cid, Miguel (Data de defensa: 2016-02-10)
The IEEE 802.11 standard was not initially designed to provide multi-hop capabilities. Therefore, providing a proper traffic performance in Multi-Hop IEEE 802.11 Wireless Networks (MIWNs) becomes a ...
Figuerola Fernández, Sergi (Data de defensa: 2016-01-25)
This work was developed during a period where most of the optical management and provisioning system where manual and proprietary. This work contributed to the evolution of the state of the art of optical ...
Rojas Hernández, Miguel Ángel (Data de defensa: 2019-11-20)
Nowadays, the growing demand for frequency-free bands for new emerging wireless technologies and fixed frequency allocation policies in the use of the radio spectrum have resulted in a saturation of the ...
Blanco Botana, Luis (Data de defensa: 2017-07-22)
This dissertation deals with different subset selection problems in wireless communications systems. These type of problems have a combinatorial nature, which makes them computationally intractable for ...
Yahyavi, Mehran (Data de defensa: 2016-03-18)
Power amplifiers (PAs) are one of the most crucial elements in wireless standards becasue they are the most power hungry subsystems. These elements have to face an important issue, which is the power ...
Torrellas Socastro, Marc (Data de defensa: 2016-02-10)
The emergence of very capable mobile terminals, e.g. smartphones or tablets, has dramatically increased the demand of wireless data traffic in recent years. Current growth forecasts elucidate that ...
Calvo Fullana, Miguel (Data de defensa: 2017-07-25)
Long thought to be an unattainable ambition, self-sustainable and green-powered wireless networks are rapidly becoming a reality. This is driven by recent hardware improvements in what is known as Energy ...
