Smart Grids

The Smart Grid is a new concept of integrating the ICT (Information and Communications Technology) over the electric power grid. The communications architecture is intended to address intelligent management functions in power systems. The automated management and the computational inteligence will lead many advantages over the actual systems. One can itemize many of them, as flexibility, resilience, sustainability and customization. Moreover, a variety of distributed renewable energy sources (wind farms, solar panels, energy of tides, electric vehicles fleet and so on) will be integrated to the new power grid. This new concept of power integration plays its contributing role effectively in the reduction of CO2 emissions in the atmosphere leading to sustainable development.

Content-centric Networks

A Content-centric network, also called content-based network, data-oriented network or named data network, is an alternative approach to the architecture of computer networks to solve challenges in content distribution scalability, mobility, and security. It is a is a novel networking paradigm centered around content distribution rather than host-to-host connectivity. It aims to replace machines with content in the networking communication model.


Mobility models are of utmost importance, especially because mathematical analysis and simulation are vital in the design of very large-scale systems. Currently there are two typesof mobility models used in the simulation of mobile networks: traces and synthetic models.Traces are those mobility patterns that are observed in real life systems; they provide accurate information. Synthetic models attempt to realistically represent the behavior of mobile nodes without the use of traces.

Delay and Disruption Tolerant Networks (DTNs)

Recently there has been much research activity in the emerging area of Delay and Disruption Tolerant Networks (DTNs), mainly because they have the potential to connect devices and areas of the world that are under-served by current networks. DTNs are characterized by long or variable delay, intermittent connectivity, and high error rates; and overcome these problems by using store-and-forward message switching and persistent storage.


Optical Networks

Novel applications, such as video streaming and computer grids, demand a large amount of bandwidth. To satisfy the requirements of these applications, optical networks have been developed and wavelength-division multiplexing (WDM) has been considered as a major optical technology because of its high capacity to transport data.
