Heterogeneity of connection technologies and nodes mobility open new challenges in home networks control strategies. Moreover, user's needs are changing towards applications requiring high transmission speeds such as 3D gaming, enhanced interactivity and high definition video. Each of those applications puts several constraints on the network capabilities to guarantee requirements on the Quality of Service. In this paper we introduce an innovative concept based on fast load balancing algorithm operating on top of a convergence layer, in order to rapidly react to network changes and contemporaneously to satisfy strict application demands. We formulated the load balancing problem as a Multi-Commodity Flow and resolved it with a column generation approach using Lagrangian Relaxation and Dijkstra algorithm. The load balancing problem computational complexity is decreased with respect to state of the art load balancing solutions based on linear programming techniques. Proof of concept simulation results are reported

This work deals with the satisfaction of the quality of\ud experience (QoE) requirements in the perspective of the emerging\ud future Internet framework. The evolution of the Internet is pointing\ud out its limitations, which are likely to hinder its potential. In\ud this respect, this paper introduces an innovative approach to cope\ud with some key limitations of the present communication networks.\ud In particular, the need of efficiently utilizing the available network\ud resources and of guaranteeing the user expectations in terms of\ud QoE requires a full cognitive approach, which is realized by the\ud introduction of a novel architecture design, the so-called future\ud Internet core platform. The future Internet core platform aims\ud at bringing together the applications world with the network\ud world, hence introducing a further cognitive level while enabling a\ud new generation of applications: network-aware applications. This\ud paper is concerned with an important aspect of the intelligent\ud connectivity between applications and network: the service class\ud association, which, if performed with a cognitive approach, can\ud yield some important improvements and advantages in the emerging\ud information era. The key idea presented in this paper is a\ud real-time dynamic control procedure for the selection of the optimal\ud service class. The approach is based on theoretical considerations\ud validated by a proof-of-concept simulation

Home networks have become heterogeneous environment hosting a variety of wireless and wired telecommunication technologies. Currently there no exist any intelligent energy saving mechanism to control the home networks. In this paper we propose an energy-aware strategy that integrate Wireless Sensor Network (WSN) with a convergent digital home network. We aim to demonstrate that a WSN can act as a dependable control plane to manage the high speed home network. While the home network nodes can be deactivated, the WSN is always on and, due to the low data rate required to properly work, it consumes a very limited quantity of energy. This mutual interaction leads to a substantial reduction of the energy consumptions. Simulation results show that this strategy is effective in different scenarios and provides a tangible economic benefit

In the present paper the authors show how the application of Semantic Web technologies, i.e. ontology and rule languages, can be used to describe situations and enhance situation awareness providing also suggested actions to the human operator in a data fusion architecture aimed at airport security. The paper presents the ontology design, i.e. main classes and relationship, and the possible roles for situation categorization including the application of rules. In addition, an insight of alternative options including their pros and cons in terms of representation expressivity and complexity, is provided. An analysis of the architectural issues and their impacts considering available technologies and their limitations have been included in the present paper. In order to validate the proposed approach both from the representation and from the complexity point of view, a comparison with a well-established framework, i.e. Situation Ontology developed by Vistology, has been carried out in terms of language complexity and dynamic behaviour in order to assess the performance and limits of the proposed system. © 2014 IEEE
