A Mathematical Approach to the Automatic Discovery of Interesting Questions

Rafael García, Ingeniero de Investigación, IMDEA Networks Institute
In this presentation we will explain a new mathematical procedure for the automatic discovery of interesting research questions. We propose to classify research topics according to their relevance (how important is the topic) and nescience (a measure of our current understanding of that topic).

Defensa Tesis Doctoral: Structural Issues and Energy Efficiency in Data Centers

Jordi Arjona Aroca, Estudiante de doctorado, IMDEA Networks Institute
With the rise of cloud computing, data centers have been called to play a main role in the Internet scenario nowadays. Despite this relevance, they are probably far from their zenith yet due to the ever increasing demand of contents to be stored in and distributed by the cloud, the need of computing power or the larger and larger amounts of data being analyzed by top companies such as Google, Microsoft or Amazon.

Modeling D2D Communications in Cellular Access Networks via Coupled Processors

Christian Vitale, Estudiante de doctorado, IMDEA Networks & Universidad Carlos III of Madrid (España)
We present a first fully analytical approach to performance evaluation of D2D communication systems, which does not assume transmitters to have always a packet to transmit. In particular, we adopt a Coupled Processors model to describe a cellular scenario with D2D users sharing radio resources with cellular users, i.e., adopting in-band underlay D2D schemes. We derive sufficient conditions for stability of such system, and we characterize the effects of D2D transmissions on cellular user performances.

The Routing Continuum in Wireless Sensor Networks

Omprakash Gnawali, Assistant Professor, University of Houston, EE.UU.
Traditional distance vector routing and efficient flooding-based routing can be considered the two ends of the routing continuum in wireless sensor networks. The former uses a graph metaphor to find the best paths between the end-points in a network.

Remote Peering: More Peering without Internet Flattening

Ignacio Castro, Estudiante de doctorado, IMDEA Networks Institute and Internet Interdisciplinary Institute, Open University of Catalonia (España)
The trend toward more peering between networks is commonly conflated with the trend of Internet flattening, i.e., reduction in the number of intermediary organizations on Internet paths. Indeed, direct peering interconnections bypass layer-3 transit providers and make the Internet flatter.

Algorithms for Software-Defined Distributed Systems

Stefan Schmid, Senior Research Scientist, TU Berlin / Telekom Innovation Laboratories (T-Labs), Berlín, Alemania
Today's distributed systems are increasingly virtualized and software-defined. While in principle, this introduces interesting new opportunities, e.g., in terms of resource allocation and traffic engineering, it also raises the question of how to algorithmically exploit the new flexibilities, and how to operate and control such dynamic systems without violating correctness and consistency properties.

Quantifying Information Overload in Social Media and its Impact on Social Contagions

Manuel Gómez Rodríguez, Tenure-track research group leader, Max Planck Institute for Software Systems, Saarbrüecken, Alemania
Information overload has become an ubiquitous problem in modern society. Social media users and microbloggers receive an endless flow of information, often at a rate far higher than their cognitive abilities to process the information.

Defensa Tesis Doctoral: A system for the detection of Limited Visibility in BGP

Andra Lutu, Estudiante de doctorado, IMDEA Networks Institute
The performance of the global routing system is vital to thousands of entities operating the Autonomous Systems (ASes) which make up the Internet. The Border Gateway Protocol (BGP) is currently responsible for the exchange of reachability information and the selection of paths according to their specified routing policies.

5G Communications: A Thousand Times More Network Capacity

Arturo Azcorra, Director, IMDEA Networks Institute; Catedrático, Universidad Carlos III of Madrid
Sólo hace un año los españoles comenzaron a disfrutar de las redes móviles 4G, que aumentan diez veces la velocidad de transmisión de datos móviles, en comparación con la tercera generación. El desarrollo de la red 5G ya está en marcha, con la intención de proporcionar una red con una capacidad mil veces mayor que la de la anterior generación.
