This Chapter proposes a novel Cognitive Framework as reference architecture for the Future Internet (FI), which is based on so-called Cognitive Managers. The objective of the proposed architecture is twofold. On one hand, it aims at achieving a full interoperation among the different entities constituting the ICT environment, by means of the introduction of Semantic Virtualization Enablers, in charge of virtualizing the heterogeneous entities interfacing the FI framework. On the other hand, it aims at achieving an inter-network and inter-layer cross-optimization by means of a set of so-called Cognitive Enablers, which are in charge of taking consistent and coordinated decisions according to a fully cognitive approach, availing of information coming from both the transport and the service/content layers of all networks. Preliminary test studies, realized in a home environment, confirm the potentialities of the proposed solution

This paper presents an original discrete-time, distributed, non-cooperative load balancing algorithm, based on mean field game theory, which does not require explicit communications. The algorithm is proved to converge to an arbitrarily small neighborhood of a specific equilibrium among the loads of the providers, known as Wardrop equilibrium. Thanks to its characteristics, the algorithm is suitable for the Software Defined Networking (SDN) scenario, where service requests coming from the network nodes, i.e., the switches, are managed by the so-called SDN Controllers, playing the role of providers. The proposed approach is aimed at dynamically balancing the requests of the switches among the SDN Controllers to avoid congestion. The paper also suggests the adoption of SDN Proxies to improve the scalability of the overall SDN paradigm and presents an implementation of the algorithm in a proof-of-concept SDN scenario, which shows the effectiveness of the proposed solution with respect to the current approaches.

The purpose of this paper is to present the SHIELD holistic approach: an innovative methodology to address Security, Privacy and Dependability (SPD) in the context of Embedded Systems (ES) by means of control science theory. The SHIELD methodology consider the SPD functionalities offered by the generic atomic component of a complex system at 3 different levels: node, network and middleware. Then these technologies are enhanced with a fourth vertical layer named overlay that provides composability functionality, thus creating a framework able to dynamically reconfigure to satisfy the user needs in terms of SPD, in different scenarios. In order to achieve this objective, the use of specific SPD metrics (derived from recognized standards for security, like the ISO/IEC 15408), is proposed. The results presented in this work have been developed in the scope of the pSHIELD ARTEMIS-JU project and are currently under investigation in the nSHIELD project. ?????? 2012 IEEE

Gigabit home networks represent a key technology to make the Future Internet success a reality. The OMEGA European project [1] aims to define and demonstrate such networks. Consumers will require networks to be simple to install, without the need of any new wire. To achieve this, gigabit radio links and wireless optics communications will provide wireless connectivity within the home and its surroundings. Power-line communications potentially combined with robust RF will provides a home backbone "without new wires." To make this network ubiquitous, seamless and robust a technologyindependent MAC layer will ensure its global control and provide connectivities to any number of devices the user wishes to connect to it in any room in a house or a Oat. In order to make this vision come true, substantial progress is required in the fields of optical-wireless and RF physical layers, in protocol design, and in systems architectures.
