Due to the surging increase in data traffic demand, operators try to enhance the coverage and network capacity by intensive spatial reuse. The limiting factor in networks with high spatial reuse is aggregate network interference, which depends strongly on the locations of the interferers.

Visible light communications are becoming a major short range wireless communication technology. Incorporating communication into existing lighting infrastructure, VLCs are potential candidate for future indoor communications.

Understanding complex physical systems requires knowledge of the interactions among their constituents, in order to be able to predict emergent behaviors (i.e., of the system as a whole).

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.

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

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

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.

While substantial effort has been devoted to understand fraudulent activity in traditional online advertising (search and banner), more recent forms such as video ads have received little attention.
