In this paper we propose an energy saving strategy by integrating a Wireless Sensor Network (WSN) with a high speed, hybrid home network. The main objective is to demonstrate that a WSN can act as a dependable control plane, where low data rate control packets can flow even when the high speed home network is shut down. While the home network nodes or some of each node's network technologies can be deactivate, 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 between the high speed home network and the WSN allows at the same time to achiveve the convergence of heterogeneous communication technologies in the home environment and leads to a substantial reduction of the energy consumptions. Simulation results show that this strategy is effective in a multitude of scenarios and provides a tangible economical benefit.

We consider a network scenario where each class of service is characterized by a different constant bit rate and an associated revenue. We formulate the problem as a Semi-Markov Decision Process, and we use a model based Reinforcement Learning approach. Other traditional algorithms require an explicit knowledge of the state transition models while our solution learns it on-line. We will show how our policy provides better solution than a classic greedy algorithm.

In the literature there are a number of service discovery protocols, each of them excelling in its particular field of application, and also a number of extensions to usual discovery architectures, especially to empower their descriptive capabilities. In any case it is missing an architecture able to solve the problem of the inter-working among different service discovery approaches -typically, each service discovery protocol has its own rules, and limitations -instead to have a common architecture able to use all actual protocols in the same way. In this paper we propose a service discovery framework which addresses this problem, introducing the concept of ontology -based multi-protocol service discovery: the proposed architecture, apart to use OWL to enhance, in the same common way, all descriptive capabilities of discovery protocols, is tailored to be compatible with all discovery protocols, due to the use of an opportune interface. This architecture has been deployed and tested using the SLP and UPnP service discovery protocols, integrated with the powerful descriptive functionalities offered by OWL. This work describes the results of the design activity which is being carried out within DAIDALOS II (designing advanced network interfaces for the delivery and administration of location independent, optimised personal services), a project granted in the European 6th Framework Research Programme, within the IST (Information Society and Technology) thematic area.

The need to manage heterogeneous resources, over heterogeneous systems requires a cognitive approach. We propose a cognitive framework based on semantic virtualization of the main internet entities: actors, resources and applications. By means of dynamic generic enablers and proper interfaces, the cognitive framework can operate over heterogeneous environments, translating them into semantic-enriched homogeneous metadata. This virtualization allows the cognitive framework to manage the available resources using advanced, technology independent algorithms. A key role is played by the interfaces which, as the paper shows, can introduce a further cognition level.

These networks will be realized through the integration of heterogeneous communication technologies that will coexist and interoperate thanks to the introduction of a convergence layer, namely the Inter-MAC layer, as defined, for example, within the EU OMEGA project. Such layer is capable to efficiently guarantee a pre-defined level of Quality of Service to modern applications by means of an advanced management of the network resources. However, a unified mechanism to initiate the high level network application, especially in order to provide the signalling information containing user's desired level of QoS to the Inter-MAC layer and to orchestrate the setup procedure is actually missing. This document aims at proposing an innovative architectural and procedural definition of the home context considering the presence of two existing protocols, namely UPnP-QoS and SIP, and their coupling with Inter-MAC to provide a QoS enabled framework in the home context.

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.

Current home networks are still not capable to cope with the tight requirements asked by these kind of applications. Moreover, many underlying wired and wireless transmission technologies are available, but no solution to reach a convergent framework is available. In this paper, we present a preliminary software implementation of a novel solution, called Inter-MAC, that realizes the convergence at MAC layer enabling a reliable and high performance delivery of application data and services. Our results show how it is possible to split flows onto different technologies when the overloading of a single link would cause unacceptable delay and packet loss results. This is done in a plug and play fashion: loading a kernel module in a running Linux machine.
