En los últimos años, la creciente concienciación social sobre la necesidad de contener el consumo de energía dentro de tasas sostenibles ha captado el interés de las comunidades empresarial y académica. En este escenario, Internet – y más en general las TIC – puede desempeñar un doble papel, siendo a la vez un importante consumidor de energía y un actor potencial en un cambio de dirección hacia un uso más inteligente de los recursos energéticos.

In 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.

While some see in Border Gateway Protocol (BGP) a routing ambrosia to be enshrined, others perceive a basis of serious Internet connectivity limitations. Because the interdomain routing protocol realizes contracts between Autonomous Systems (ASes), this paper argues that contractual and routing issues need to be tackled jointly to overcome the connectivity limitations. We propose Route Bazaar, a backward-compatible system for flexible Internet connectivity. Inspired by the decentralized construction of trust in cryptocurrencies, Route Bazaar uses a decentralized public ledger and cryptography to provide ASes with automatic means to form, establish, and verify end-to-end connectivity agreements.

Today the Internet, as we know it, stands as an increasingly important element in every societal domain. Never before have people (and machines) had such an amount of potential content at their fingertips (or interfaces), and different ways to share it.

Mobile data traffic is increasing rapidly and wire- less spectrum is becoming a more and more scarce resource. 

In the last years, the commercial deployment of data services in mobile networks has been evolving quickly, providing enhanced radio access technologies and more efficient network architectures.

Spectrum scarcity and ever increasing densities of wireless network deployments have recently led to an opening of the 60 GHz millimeter-wave bands for unlicensed communication. In contrast to the previously used ISM bands below 5 GHz, a massive amount of 6-9 GHz of bandwidth is available at these frequencies. Usage of these resources is considered for wireless LAN and 5G cellular networks and with the ratification of the IEEE 802.11ad standard in December 2012, wireless LAN is about to bring millimeter-wave communication to the commercial market.

Networking research and development is an important field in information technology and its importance grows with the rise of the Internet and the ubiquity of worldwide communication.

Distributed Storage Systems ensure data availability and survivability be replicating data in geographically disperse storage devices. Replication allows multiple processes to access the data concurrently each communicating with different storage device.

In this work, propagation dynamics on social networks are studied in order to identify the most influential users. For this purpose, diffusion data has been collected during 4 weeks from a microblogging OSN (online social network) called Tumblr.
