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.

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.

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. In particular, we show that: (i) somehow surprisingly, almost all considered services exhibit quite different temporal usage patterns; (ii) in contrast to such temporal behavior, spatial patterns are fairly uniform across all services; (iii) when looking at usage patterns at different locations, the average traffic volume per user is dependent on the urbanization level, yet its temporal dynamics are not. Our findings do not only have sociological implications, but are also relevant to the orchestration of network resources.

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.

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.

Ander Galisteo, a PhD student in Telematics Engineering at the research institute IMDEA Networks, has been invited to give this talk aimed at scientific dissemination within the program "Young Scientists 2017" of the Madrid Science.

University Carlos III of Madrid (UC3M) participates in the seventeenth edition of the Madrid Science Week with more than thirty activities (all free-of-charge ) that will offer a first-hand knowledge of the Institution's R&D program. IMDEA Networks is collaborating with UC3M in the staging of a multimedia, theatrical and informative show that explores the effects of 5G technology in our everyday lives. The show will held on November 7th in the Auditorium of the UC3M. 

Access to a common (communication) resource has been one of the fundamental problems in the various networking technologies that have emerged over the last half a century.
