Can we build platforms that are decentralized, democratic, and where profit is distributed? In this talk, I will present P2P Models (p2pmodels.eu), a new ERC 1.5M€ research project to build Blockchain-powered organizations.

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. IMDEA Networks colabora en un espectáculo multimedia, teatral y divulgativo para explorar los efectos de la tecnología 5G en la vida cotidiana  que se celebrará el 7 de noviembre en el Auditorio de la UC3M.  

Enterprise Networking has a strong set of requirements in terms of resiliency, reliability and resources usage. With current approaches being based on monolithic and expensive infrastructures using dedicated overlay links, providers are moving to more economical hybrid solutions that encompass private dedicated links with public/regular Internet connections.

Among the primary challenges of the roll out 5G networks are the protocol level issues it faces. Issues such as mm-wave beamforming, initial access, MAC layer design, mm-wave localization, network architectures, are all proving to be key elements that must be addressed. Both industry and academic research is still at an early phase of this work and for it to progress work must be done on a number of fronts in terms of test and measurement and other issues. This webinar will examine the work that is being done in addressing these issues and some of the solutions that have been developed.

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.

The seminar will provide an introduction to the Project Loon, a network of balloons designed by Google to extend Internet connectivity to people in rural and remote areas worldwide. We will review its main technical characteristics and how it has evolved in the last couple of years. It will also review the activities carried out in cooperation with Telefónica in Latam, including technical trials in Chile and Perú, and provide an assessment of the main issues the project faces to become a sustainable commercial system. Although not likely to be covered in the seminar, we will also provide some information about other alternatives to provide connectivitivy using aerial networks, like

Despite the hype about blockchains and distributed ledgers, no formal abstraction of these objects has been proposed. To face this issue, in this paper we provide a proper formulation of a distributed ledger object. In brief, we define a ledger object as a sequence of records, and we provide the operations and the properties that such an object should support. 

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. In this concept users iteratively revise their strategies, which include bidding for spectrum, route selection and relaying incentives, to achieve their quality of service requirements. Further, a reinforcement learning algorithm will be discussed to automatize the bidding process based on users¹ previous experiences. Then, a collaborative cognitive dynamic network architecture (CDNA) will be outlined where mobile devices share their connectivities acting as access points for other users and harvest available spectrum.

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.
