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 ...
Contributions to the algorithms and methodologies for virtual infrastructure provisioning
Virtualization is defined as the process consisting of building a virtual resource on top of one or several physical resources, depending on the selected paradigm: aggregation or partitioning. From the net- working ...
Improvements to end-to-end performance of low-power wireless networks
Over the last decades, wireless technologies have become an important part of our daily lives. A plentitude of new types of networks based on wireless technologies have emerged, often replacing wired solutions. In this ...
Handoff management for infotainment services over vehicular networks
Intelligent Transportation Systems (ITS) has impulsed the vehicular communications at the present time. The vehicular communications field is a hot research topic and is attracting a great interest in the automotive industry ...
Wake-up radio systems : design, development, performance evaluation and comparison to conventional medium access control protocols for wireless sensor networks
During the recent years, the research related to Wake-up Radio (WuR) systems has gained noticeable interest. In WuR systems, a node initiating a communication first sends a Wake-up Call (WuC) by means of its Wake-up ...
Contribution to the improvement of the performance of wireless mesh networks providing real time services
Nowadays, people expectations for ubiquitous connectivity is continuously growing. Cities are now moving towards the smart city paradigm. Electricity companies aims to become part of smart grids. Internet is no longer ...
Certificate status information distribution and validation in vehicular networks
Vehicular ad hoc networks (VANETs) are emerging as an functional technology for providing a wide range of applications to vehicles and passengers. Ensuring secure functioning is one of the prerequisites for deploying ...
Contributions to the performance evaluation and improvement of the IPv6 routing protocol for low-power and lossy networks
Wireless Sensor Networks (WSNs) have become increasingly important. These networks comprise sensor and actuator nodes that enable intelligent monitoring and control applications in a wide spectrum of environments including ...
New Architectures for ubiquitous networks : use and adaptation of internet protocols over wireless sensor networks
This thesis focuses on the study of low-resource demanding protocols, communication techniques and software solutions to evaluate, optimise and implement Web service in WSNs. We start analysing the Web service architectures ...
Traffic and mobility management in large-scale networks of small cells
The growth in user demand for higher mobile data rates is driving Mobile Network Operators (MNOs) and network infrastructure vendors towards the adoption of innovative solutions in areas that span from physical layer ...
Privacy protection of user profiles in personalized information systems
In recent times we are witnessing the emergence of a wide variety of information systems that tailor the information-exchange functionality to meet the specific interests of their users. Most of these personalized information ...
On codes for traceability schemes: constructions and bounds
A traceability or fingerprinting scheme is a cryptographic scheme that facilitates the identification of the source of leaked information. In a fingerprinting setting, a distributor delivers copies of a given content to a ...
Resource management research in ethernet passive optical networks
The last decades, we have witnessed different phenomenology in the telecommunications sector. One of them is the widespread use of the Internet, which has brought a sharp increase in traffic, forcing suppliers to continuously ...
