In this paper, we propose Floating Band D2D, an adaptive framework to exploit the full potential of Device-to-Device (D2D) transmission modes.

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

In this paper we challenge the common evaluation practices used for Virtual Machine (VM) consolidation, such as simulation and small testbeds, which fail to capture the fundamental trade-off between energy consumption and performance. We identify a number of over-simplifying assumptions which are typically made about the energy consumption and performance characteristics of modern networked systems.

Traditional distance vector routing and efficient flooding-based routing can be considered the two ends of the routing continuum in wireless sensor networks. The former uses a graph metaphor to find the best paths between the end-points in a network.

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.

The trend toward more peering between networks is commonly conflated with the trend of Internet flattening, i.e., reduction in the number of intermediary organizations on Internet paths. Indeed, direct peering interconnections bypass layer-3 transit providers and make the Internet flatter.

With the rise of cloud computing, data centers have been called to play a main role in the Internet scenario nowadays. Despite this relevance, they are probably far from their zenith yet due to the ever increasing demand of contents to be stored in and distributed by the cloud, the need of computing power or the larger and larger amounts of data being analyzed by top companies such as Google, Microsoft or Amazon.

Tablets and smartphones have become the favorite gateway to the Internet for a majority of users. Being equipped with plenty of sensors, these devices enable far more than traditional web browsing.

El congreso “IFIP Performance” reúne a investigadores interesados en la comprensión y mejora del desempeño de los sistemas de comunicación mediante modelos cuantitativos y técnicas de solución de última generación.

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.
