Nowadays, we live in a modern society in which people and devices are interconnected anywhere and anytime. Under this premise, both the infrastructure and the services offered have evolved and diversified in a drastic way. ...
Contributions based on cross-layer design for Quality-of-Service provisioning over DVB-S2/RCS Broadband Satellite Systems Nowadays, geostationary (GEO) satellite infrastructure plays a crucial role for the provisioning of ...
de la Tesis<br/><br/>Las redes de hoy en día presentan un gran crecimiento, una alta complejidad de gestión y los nuevos servicios tienen requerimientos cada vez más estrictos. Es por ello que las plataformas de gestión ...
Bluetooth Low Energy (BLE) has become a popular Internet of Things (IoT) technology. However, it was originally designed to only support the star topology. This PhD thesis investigates and evaluates different Bluetooth Low ...
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 ...
Ever-increasing energy consumption, the depletion of non-renewable resources, the climate impact associated with energy generation, and finite energy-production capacity are important concerns worldwide that drive the ...
The most essential part of the Internet of Things (IoT) infrastructure is the wireless communication system that acts as a bridge for the delivery of data and control messages between the connected things and the Internet. ...
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 ...
(English) The main objective of this thesis is contributing to IPv6 support over Low Rate Low Power Wireless Networks (LRLPWNs). One family of LRLPWNs is Low Power Wide Area Networks (LPWANs), which includes technologies ...
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 ...
Next-Generation Networks (NGNs) will converge the existing fixed and wireless networks. These networks rely on the IMS (IP Multimedia Subsystem), introduced by the 3GPP. The presence service came into being in instant ...
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 ...
The Wi-Fi technology has been in the recent years fostering the proliferation of attractive mobile computing devices with broadband capabilities. Current Wi-Fi radios though severely impact the battery duration of these ...
A recommender system is an automatic system that, given a customer model and a set of available documents, is able to select and offer those documents that are more interesting to the customer. From the point of view of ...
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 ...
(English) Low Power Wide Area Network (LPWAN) technologies have gained significant momentum as wireless solutions for implementing Internet of Things (IoT) applications and services. The unique set of LPWAN features, such ...
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 ...
Nowadays, video streaming applications are the most bandwidth-hungry applications and this tendency is envisaged to grow exponentially. With the proliferation of multimedia capable devices, multimedia services have to ...
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 ...
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. ...
