Contributions towards softwarization and energy saving in passive optical networks
Ths thesis is a result of contributions to optimize and improve the network management systme and power consumption in Passive Optical Network (PON). Passive Optical Network elements such as Optical Line Terminal (OLT) and ...
Energy sustainability of next generation cellular networks through learning techniques
The trend for the next generation of cellular network, the Fifth Generation (5G), predicts a 1000x increase in the capacity demand with respect to 4G, which leads to new infrastructure deployments. To this respect, it is ...
Design and performance evaluation of smart dissemination of emergence messages in vehicular ad-hoc networks
The growing demand to improve road safety and optimize road traffic has generated great interest in vehicular ad-hoc network (VANETs). Serious traffic accidents can cause financial losses, physical disability, and even ...
Energy-aware routing techniques for software-defined networks
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 even more concerning ...
Analysis, modelling and protection of online private data
Online communications generate a consistent amount of data flowing between users, services and applications. This information results from the interactions among different parties, and once collected, it is used for a ...
Contributions to the evolution of next generation WLANs
The explosive growth in usage of IEEE 802.11 based WLAN networks has resulted in dense deployments in diverse environments and has made the concept of anytime - anywhere data connectivity a realm of commercial reality. The ...

Recent developments in optical communication systems have increased the performance of optical networks. Low attenuation fiber optics, high spectral purity lasers and optical amplifiers, among others, are systems that have ...
Contribution to the design of VANET routing protocols for realistic urban environments
One of the main concerns of the cities' administration is mobility management. In Intelligent Transportation Systems (ITS), pedestrians, vehicles and public transportation systems could share information and react to any ...
Secure identity management in structured peer-to-peer (P2P) networks
Structured Peer-to-Peer (P2P) networks were proposed to solve routing problems of big distributed infrastructures. But the research community has been questioning their security for years. Most prior work in security ...
Scalability and robustness in software-defined networking (SDN)
The simplicity of Internet design has led to enormous growth and innovation. In recent decades several network technologies, services and applications have appeared, which demand specific network requirements for their ...
Contributions to interoperability, scalability and formalization of personal health systems
The ageing of the world's population combined with unhealthy lifestyles are contributing to a major prevalence of chronic diseases. This scenario poses the challenge of providing good healthcare services to that people ...
Contributions to efficient and secure exchange of networked clinical data : the MOSAIC system
The understanding of certain data often requires the collection of similar data from different places to be analysed and interpreted. Multi-agent systems (MAS), interoperability standards (DICOM, HL7 or EN13606) and ...
Topologías para la distribución de contenidos en redes de comunicación
The peer-to-peer (P2P) overlay networks are distribution topologies that take advantage of the ability that their nodes have to forward the information that they receive. For the particular case of video transmission using ...
Individual verifiability in electronic voting
This PhD Thesis is the fruit of the job of the author as a researcher at Scytl Secure Electronic Voting, as well as the collaboration with Paz Morillo, from the Department of Applied Mathematics at UPC and Alex Escala, PhD ...
Contributions to the routing of traffic flows in multi-hop IEEE 802.11 wireless networks
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 significant challenge. ...
Contributions to provide a QoS-aware self-configured framework for video-streaming services over ad hoc networks
Ad hoc networks have attracted much attention from the research community over the last years and important technical advances have risen as a consequence. These networks are foreseen as an important kind of next generation ...
