In the last decade, cellular networks are undergoing with a radical change in their basic design foundations. The huge increase in traffic demand requires a novel design of future cellular networks.

Mixing time is a global property of a network that indicates how fast a random walk gains independence from its starting point. Mixing time is an essential parameter for many distributed algorithms, but especially those based on gossip.

On 6th of November 2015 IMDEA Materials, one of the seven IMDEA Institutes, opened its doors for the 1st IMDEA Conference: Science, Business & Society.

Technology now offers the possibility of delivering a vast range of low-cost people-centric services to citizens. Internet of Things (IoT) supporting technologies are becoming robust, viable and cheaper.

Several challenges persist in what concerns wireless sensor networks, the Internet of Things, and the use of these technologies in human-centric environments.

Programmable networks or Software Defined Networking (SDN) offers new opportunities to manage computer networks: Make networks smart, introduce new service faster.

How do science and movies get along? Is it true that, most of the times, truth is stranger than fiction?

In this thesis, signal propagation variations that are experience over the frequency resources of IEEE 802.11 Wireless Local Area Networks (WLANs) are studied.

Modern wearable devices allow monitoring vital parameters such as heart or respiratory rates, electrocardiogram, photo-plethysmographic or even video signals, and are being massively commercialized in the consumer electronics market.

The availability of data on digital traces is growing to unprecedented sizes, but inferring actionable knowledge from large-scale data is far from being trivial.
