A multitude of wireless technologies are used within air traffic communication. From a conceptual perspective, all of them are insecure as security was never part of their design and the evolution of wireless security in aviation did not keep up with the state of the art.
Future networks based on virtualization will enable on-the-fly instantiation of services in the form of "network slices". In this talk we will focus on a fundamental resource allocation problem in this context, that of finding a minimum cost embedding of a network slice onto a graph representing the available resources of our architecture.
Wireless networks are progressively displacing service provisioning towards the edge to accommodate the increasing traffic demands. This paradigm shift calls for smart policies to efficiently share network resources and ensure service delivery. In this talk, a concept of bidding and tipping for spectrum auctioning will be presented.
Millimeter-wave devices must use highly directional antennas to achieve GBit/s data rates over reasonable distances due to the high path loss. As a consequence, it is important to precisely align the antenna beams between sender and receiver. Even minor movement or rotation of a device can result in beam misalignment and thus a strong performance degradation.
This integrated demo will interconnect different transport technologies carrying backhaul traffic, fronthaul traffic and both in one network, which demonstrates the 5G-Crosshaul data plane technologies developed in the project.
La Universidad Carlos III de Madrid (UC3M) participa en la decimoséptima edición de la Semana de la Ciencia de Madrid con más de una treintena de actividades gratuitas que permiten conocer de primera mano la I+D+i de la institución.
Ander Galisteo, estudiante de doctorado en Ingeniería Telemática en el instituto de investigación IMDEA Networks, ha sido invitado a impartir esta charla de divulgación científica dentro del programa "Jóvenes Científicos 2017" de la Semana de la Ciencia de Madrid.
We investigate how individual mobile services are consumed at a national scale, by studying data collected in a 3G/4G mobile network deployed over a major European country. Through correlation and clustering analyses, our study unveils a strong heterogeneity in the demand for different mobile services, both in time and space.
¿Qué pueden aportar la ciencia y la tecnología al trabajo policial? ¿Quién es más inquisitivo, un científico o un policía?
Queueing theory, the set of probabilistic techniques that study waiting lines or queues, is a fundamental tool to analyze the performance of modern telecommunication networks. In this talk, we present the results of the performance analysis of two queueing systems.
