Network-Aware P2P-TV Application over Wise Networks

A Small or Medium-Scale Focused Research Project of ICT Call 1 FP7-ICT-2007-1. Grant Agreement no.: 214412.

TV services over the Internet can be provided either exploiting IP multicast functionalities or relying on a pure end-to-end (P2P) approach. The first technique unfortunately, will only work on a network infrastructure controlled by a single broadband operator due to limitations of IP multicast facilities. On the contrary, the P2P approach has been successfully exploited to overcome these limits and can potentially offer a scalable planetary infrastructure. Recently, several P2P-TV systems started to show up, with the last generation offering High Quality TV (P2P-HQTV) systems, providing a ubiquitous access to the service. These same potentialities of P2P-TV systems constitute a worry for network carriers since the traffic they generate may potentially grow without control, causing a degradation of quality of service perceived by Internet users or even the network collapse (and the consequent failure of the P2P-HQTV service itself!).

Starting from these considerations the NAPA-WINE project, funded by the European Commission within the seventh framework programme, aims at:

  1. providing a careful analysis of the impact that a large deployment of both general P2P-TV and P2P-HQTV services may have on the Internet, through an in detailed characterization of the traffic they generate;
  2. providing guidelines for P2P-TV developers regarding the design of systems that minimize the impact on the underlying transport network while optimizing the user perceived quality;
  3. providing a road map for Internet Service Providers to better exploit the network bandwidth by showing simple and minimum cost actions that can be taken in presence of P2P-TV traffic.

TRITON

Triton

Trentino Research Innovation for Tunnel mONitoring

TRITon is a research and innovation project funded by the project members and the Autonomous Province of Trento (Provincia Autonoma di Trento, PAT) aimed at advancing the state of the art in the management of road tunnels, specifically to improve safety and reduce energy costs. To achieve these goals, TRITon will merge research on state-of-the-art technology into the established practices of road tunnel infrastructures, supported by project members that include local research centers and companies working in the field.
An example application, central in TRITon, is adaptive lighting. In current deployments, the light intensity inside the tunnel is typically regulated based on design parameters and the current date and time, and regardless of the actual environmental conditions. As it can be experienced when driving through a road tunnel too bright or too dark, this potentially determines a waste of energy, as well as a potential safety hazard. In TRITon, the light intensity inside the tunnel will instead be regulated through a wireless sensor network (WSN). This will relay sensed light information to the control station, which will exploit such information for fine-grained adaptation to environmental condition, significantly reducing costs and improving safety. A dedicated laboratory has been established to support TRITon's research and development activities. However, to bring state-of-the-art research and technology like WSN into road tunnel management, the traditional lab-centered research is not sufficient. Indeed, TRITon will transfer its results in real test-sites, four operational tunnels on road SS 45bis near Trento. This will provide not only the ultimate test for the project outcomes, but also a direct and measurable benefit to the local population.
