Programmable networks or Software Defined Networking (SDN) offers new opportunities to manage computer networks: Make networks smart, introduce new service faster.
Seguir leyendo arrow_right_altThe availability of data on digital traces is growing to unprecedented sizes, but inferring actionable knowledge from large-scale data is far from being trivial.
Seguir leyendo arrow_right_altMixing 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.

Seguir leyendo arrow_right_altMiddleboxes, such as proxies, firewalls and NATs play an important role in the modern Internet ecosystem. On one hand, they perform advanced functions, e.g. traffic shaping, security or enhancing application performance.
Seguir leyendo arrow_right_altTargeting an increasing number of potential application domains, wireless sensor networks (WSN) have been the subject of intense research, in an attempt to optimize their performance while guaranteeing reliability in highly demanding scenarios.
Seguir leyendo arrow_right_altThe increasing demand for ubiquitous, high-speed and high-performance Internet access challenges the economic viability of mobile network operators which cannot cope with the rate of increase of wireless traffic. Alternate means are considered to deal with the excessive traffic demand that exploit the increase of wireless networks in unlicensed parts of the spectrum, as well as of handheld devices with multiple radio interfaces.
Seguir leyendo arrow_right_altIn this talk, I will discuss an architecture called Energy Aware Disaster Recovery Network using WiFi Tethering (E-DARWIN). The underlying idea is to seamlessly integrate mobile devices carried by the people in a disaster area into the emergency response network by exploiting the WiFi tethering capability that is ubiquitously available in nearly all smartphones already.
Seguir leyendo arrow_right_altDue 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.
Seguir leyendo arrow_right_altIn a multi-channel wireless network, each node is able to use multiple non-overlapping frequency channels, by having more network interface cards.
