In order to support heterogeneous services, using the information generated by a huge number of communicating devices, the Future Internet should be more energy-efficient, scalable and flexible than today's networking platforms, and it should allow a tighter integration among heterogeneous network segments (fixed, cellular wireless, and...

We introduce a control architecture in which several (independent) multimedia clusters share the same (local or metropolitan) networking resources in a controlled framework. In particular, a central entity (i.e., the Gatekeeper) harmonizes the transmission rates of the various clusters following a given sharing policy. Each cluster, in turn,...

A distributed estimation setting is considered, where a number of sensors transmit their observations of a physical phenomenon, described by one or more random variables, to a sink over noisy communication channels. The goal is to minimize a quadratic distortion measure (Minimum Mean Square Error - MMSE) under a global power constraint on the...

A cellular wireless network is considered, where multi-class call admission control is exerted locally in a number of cells. Cells are in turn organized into clusters, which play the role of a higher hierarchical control level. The whole capacity (in number of channels) available in a cluster is distributed among its cells, according to...

In an access node to a multiservice network [e.g., a base station in an integrated services cellular wireless network or the optical line terminal (OLT) in a broad-band passive optical network (PON)], the output link bandwidth is adaptively assigned to different users and dynamically shared between isochronous (guaranteed bandwidth) and...

Mobile communications are widespread in a large part of industrialized countries and cellular networks, by which mobile radio-communications are supported, can give directly or potentially a huge amount of frequently updated information on the position of their users. This information can be used to estimate on-line the traffic conditions of...

access multiplexer is considered, serving a TDM output channel with a hybrid structure, characterized by the presence of both isochronous (circuit-switched) and asynchronous (packet-switched) traffic. The isochronous traffic is, in turn, subdivided into several classes, which are distinguished according to their speed, in order to model a...

A mechanism for the estimation of the available bandwidth between two end-points of a best-effort network is presented. The estimation is obtained by a simple statistical analysis of the effect that the network has on a synchronous train of packets. The possibility of exploiting self-similar characteristics of the delay jitters is...

Besides a more widespread sensitivity to ecological issues, the interest in energy-efficient network technologies springs from heavy and critical economical needs, since both energy cost and network electrical requirements show a continuous growth, with an alarming trend over the past years. In this contribution, we explore and try to evaluate...
