This thesis focuses on how to optimize the placement of the Edge Computing infrastructure for upcoming 5G networks. To this aim, the core contributions of this research are twofold: 1) a novel heuristic called Hybrid ...
The explosion in data traffic, the physical resource constraints, and the insufficient financial incentives for deploying 5G networks, stress the need for a paradigm shift in network upgrades. Typically, operators are also ...
The explosive growth of IoT is pushing the market towards cheap, very low power devices with a strong focus on miniaturization, for applications such as in-body sensors, personal health monitoring and microrobots. Proposing ...
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 ...
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 ...
Many mechanisms that served the legacy networks till now, are being identified as being grossly sub-optimal for 5G networks. The reason being, the increased complexity of the 5G networks compared previous legacy systems. ...
The heterogeneous services with stringent requirements that are envisioned to co-exist under the fifth generation of cellular networks (5G), inexorably challenge the current Long-Term Evolution (LTE) cellular network’s ...
Society is aware that the ecological predation of the planet is due to human activity. Therefore, it is necessary to carry out actions to reverse this damage. Besides, the trend of population growth in big cities and the ...
In a commercial Internet, the traffic behavior is determined by the contracts between the ISPs and the users, where a user can be a dial-up user, or one corporate network or a group of individual customers or 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 ...
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 ...
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 ...
(English) Invoice factoring has been a popular way to provide cash flow for businesses. The primary function of a factoring system is to prevent an invoice from being factored twice. In order to prevent double factoring, ...
Older generations of wireless networks, such as 1G and 2G were deployed using leased line, copper or fibre line as backhaul. Later, in 3G and 4G, microwave wireless links have also worked as backhaul links while the ...
Bajo la etiqueta de "Modelado y análisis de sistemas fotovoltaicos" se presentan los trabajos realizados a lo largo del doctorado. Estos estudios centran su aplicación en el área de los sistemas fotovoltaicos. Tienen por ...
During the last decades, mobile network operators have witnessed an exponential increase in the traffic demand, mainly due to the high request of services from a huge amount of users. The trend is of a further increase in ...
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 ...
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 ...
Signaling in Next Generation IP-based networks heavily relies in the family of multimedia signaling protocols defined by IETF. Two of these signaling protocols are RTSP and SIP, which are text-based, client-server, ...
(English) Initial 5G networks were deployed to satisfy the users with higher data rates. Hence, to reduce the time to market and maximize the value of already deployed infrastructure, such deployments used the Non-Standalone ...
