Granelli, WORLD Kickoff, Oct. 17th, 2009 UniTN Tasks WP6: T6.4 Multimedia P2P WLAN Connections (PHASE II) To analyze QoS requirements of multimedia streaming traffic To derive guidelines in application-level (i.e. codec) and network-level (i.e. DiffServ classes, resource reservation) parameters setting Cognitive Configuration Server

11. Dipartimento di Ingegneria e Scienza dellinformazione F. Granelli, WORLD Kickoff, Oct. 17th, 2009 UniTN Tasks WP7 Field Trials and Testbed (UniTN) T7.1 WORLD Solution Integration (PHASE II+III) T7.2 Testbed (PHASE II+III) T7.3 Trials (PHASE III)

12. Dipartimento di Ingegneria e Scienza dellinformazione F. Granelli, WORLD Kickoff, Oct. 17th, 2009 The WORLD Testbed To provide a real network to implement the (selected) research products of the WORLD project + we can seize the existing WOMEN testbed + UniTN is going to have access to a regional-wide optical + wireless facility (WOTBL) - not all solutions will be suitable for integration (feasibility check) - WOTBL delivery plan still under finalization

13. Dipartimento di Ingegneria e Scienza dellinformazione F. Granelli, WORLD Kickoff, Oct. 17th, 2009 The WORLD Testbed (contd) What is already available? The WOMEN testbed is currently running at DISI premises (802.11a/5GHz) The testbed is built using Linux-based programmable APs The software is available on the WOMEN website An Open Platform for developing and validating

14. Dipartimento di Ingegneria e Scienza dellinformazione F. Granelli, WORLD Kickoff, Oct. 17th, 2009 The WORLD Testbed (contd) WOMEN Project Final Meeting Trento, Feb. 12th, 2008

15. Dipartimento di Ingegneria e Scienza dellinformazione F. Granelli, WORLD Kickoff, Oct. 17th, 2009 The WORLD Testbed (contd) 15 AP5 AP4 AP2 AP1 AP3 X X X XX

16. Dipartimento di Ingegneria e Scienza dellinformazione F. Granelli, WORLD Kickoff, Oct. 17th, 2009 The WORLD Testbed (contd) What are we missing? Long-range connectivity (soon to come, with an HiPERLAN/2 p2p connection between DISI and CREATE-NET) Users authentication (T7.3 – Intelligent Access System) Extension to multiple NICs and smart antennas Mobile Mesh Routers (solar-powered?)

17. Dipartimento di Ingegneria e Scienza dellinformazione F. Granelli, WORLD Kickoff, Oct. 17th, 2009 The WORLD Testbed (contd) An incremental approach

18. Dipartimento di Ingegneria e Scienza dellinformazione F. Granelli, WORLD Kickoff, Oct. 17th, 2009 The WORLD Testbed (contd) Perspectives for partners To deploy the testbed at their own premises To contribute to the testbed and trials Integration Roadmap (specifications at M6, delivery at M19) To have remote access to the testbed facility (to be checked)
