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.

Crowdsourced signal monitoring systems are gaining attention for capturing the wireless spectrum at large geographical scale. Yet, most of the current systems are still limited to simple power spectrum measurements reported by each sensor.

IMDEA Networks Institute annually holds a by-invitation-only thematic workshop in Madrid. The workshop accompanies a meeting of our Scientific Council comprised of prominent researchers. In addition to talks by Scientific Council members, the workshop includes invited talks by external experts in the research theme of the workshop. The goal of the 2017 event is to foster discussion about future internet applications with particular focus on networking, privacy and security challenges.

The seminar will cover the current status of the standardization in 3GPP of the new 5G radio interface (NR) and core network (NGC), including the steps undertaken for the acceleration process recently approved, that will allow for early implementations by the end of 2018. 

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.

Big Data and Cloud Computing are two paradigms that are evolving hand in hand and are revolutionizing how we live and work. The amount of data that is being generated in the world is increasing every day, and there are no indications that this trend is going to stop any time soon (if ever). 

Traditional network management only allows to deploy a predefined set of management policies whose parameters can be adapted to specific...

The Internet routing ecosystem is facing substantial scalability challenges due to continuous, significant growth of the state represented in the data plane.

IMDEA Networks is organizing its 2nd Annual International Workshop, this year focusing on Energy Efficiency and Networking on 31st May - 1st June, 2010 in Madrid, Spain. The workshop will include presentations and a panel dealing with the latest advances and challenges facing the field. Energy efficiency is becoming one of the most important issues of our time. Population growth and exhaustion of available energy sources makes clever use of energy one of the main challenges for our society. The objective of this workshop is to explore the role of networking in the general effort towards sustainable use of energy.
