From intelligent transportation to smart grid. In quest of the killer application for multiagent system technology

Since the early nineties, intelligent agents and multiagent systems have been envisioned as the key enabling technologies for the design and implementation of large-scale, open, distributed systems. After two decades, the scientific community is still in quest of the killer application that could unleash the full potential of multiagent systems. In recent years, smart infrastructures, such as intelligent transportation and smart power networks, attracted the interest of the scientific community as two paradigmatic large-scale, open, distributed systems of a great social and economical relevance. In particular the talk will focus on two examples of on-going research on the application of market-based methods for the efficient allocation of urban road networks and coalition formation for the creation of virtual power plants.

Routing and Scheduling for Power and Delay Minimization in the Powerdown Mode

Energy conservation is drawing increasing attention in data networking. One school of thought believes that a dominant amount of energy saving comes from turning off network elements. The difficulty is that transitioning between the active and sleeping modes consumes considerable energy and time. This results in an obvious trade-off between saving energy and provisioning performance guarantees such as end-to-end delays.

VIRO: Scalable and Robust Virtual-Id Routing for Future Dynamic Networks

The Internet has transformed itself into a critical global information infrastructure, and fundamentally altered the ways we access information, communicate and interact with each other, purchase goods and services, and entertain ourselves. Despite its enormous success, the Internet suffers certain well-known shortcomings, and is increasingly strained to meet the high availability, reliability, mobility, manageability and security demands of Internet applications, users, and service providers alike. Much of my research is centered on addressing the challenges posed by these new demands.

The hidden costs of mobile applications

Mobile phones and tablets can be considered as the first incarnation of the post-PC era. Their explosive adoption rate has been driven by a number of factors, with the most significant influence being touch-screens, sensors, app markets, and better cellular technologies.

T4P: Hybrid Interconnection for Cost Reduction

Economic forces behind the Internet evolution have diversified the types of ISP (Internet Service Provider) interconnections. In particular, settlement-free peering and paid peering proved themselves as effective means for reducing ISP costs. In this paper, we propose T4P (Transit for Peering), a new type of hybrid bilateral ISP relationships that continues the Internet trend towards more flexible interconnections at lower costs.

Technologies and Architecture of the Future Internet

The future Internet needs to provide enough flexibility to allow the dynamic deployment of new network protocols, support heterogeneous end-systems, provide novel communication abstractions, and exhibit inherent security and manageability. In this talk, I present an overview of various technological drivers that shape current developments in network architecture research.

Obscure Giants: Detecting the Provider-Free ASes

We study the detection of the provider-free AS set (PFS), i.e., the set of those Autonomous Systems (ASes) that reach the entire Internet without paying anyone for the traffic delivery. Using trustworthy but non-verifiable sources for sanity checks, we derive the PFS from public datasets of inter-AS economic relationships. Whereas a straightforward method for extracting the PFS performs poorly because the datasets are noisy, we develop a more sophisticated Temporal Cone (TC) algorithm that relies on topological statistics and exploits the temporal diversity of the datasets. The evaluation shows that our TC algorithm detects the PFS with a high accuracy.

Making BGP filtering an habit: Impact on policies

It is common practice for network operators, usually for traffic engineering purposes, to propagate more specific prefixes (overlapping prefixes) along with shorter prefixes that cover them. On the other hand, it can be beneficial for some Autonomous Systems (ASes) to filter such overlapping prefixes

FLAVIA: Project Plenary Meeting

La importancia de las redes inalámbricas para la Futura Internet crece a un ritmo acelerado a medida que los dispositivos móviles se convierten cada vez más en su punto de acceso. No obstante, y como consecuencia de su diseño arquitectónico rígido, las redes inalámbricas actuales no son capaces de adaptarse rápidamente a contextos y necesidades de servicio evolutivos. Creemos que la capacidad de Internet para mantenerse al día con la innovación procede directamente de su dependencia de la abstracción tradicional de una Internet basada en capas.
