MAP-tele Seminars  2009/2010

This year the MAP-Tele Seminars includes two series of invited talks. The first invited talk series is on telecommunications with an emphasis on Broadband Multimedia Communications. The second invited talk series is the Back to Basics Colloquium. Back to Basics is organized by the ECE Department at UPorto’s Faculty of Engineering and is on fundamental tools across different fields of ECE.

MAP-Tele Seminars grade will include the participation in both series of talks.

1. Back to Basics

Full information on Back to Basics is available at http://www.fe.up.pt/b2basics. The B2B talks are typically on Wednesdays at 13:00, and a free (light) lunch is provided from 12:30 to registered attendees on the same site. MAP-Tele students need to register on the B2B site.

The following is a copy of the current talks matching the MAP-Tele calendar. For updated information and talk abstract please visit the Colloquium’s web page.

Titles and Abstracts:

Seminar 10 - 18.12.2009

Speaker: Nuno Borges de Carvalho; IT Aveiro
Title: The importance of Metrology in Wireless Communication Systems – From AM/FM to SDR Systems
Abstract:
Metrology is a key point in the design and optimization of wireless communication networks, in this talk we will make a brief presentation of the metrology chain necessities from base-band to RF wireless communication scenarios. In this path we will address linear and nonlinear measurements strategies, from RF figures of merit to base band figures. Finally some recent developments referred to software radio activities will also be presented, explaining the new paradigms and envisioning the future of wireless metrology.

Seminar 12 - 15.12.2009

Speaker: André Zúquete, IEETA
Title: Fast Wi-Fi mobility with security: a cross-layer approach using network sensing
Abstract:
The layered protocol stacking model and the patches introduced by 802.11i to fix the security vulnerabilities of the original Wi-Fi architecture, leaded to extremely slow and complex handover processes. In this presentation we will how we can accelerate handovers without decreasing security requirements, and even adding extra security services to the base Wi-Fi protocol. The key idea is to make use of network scanning processes, which are naturally conducted by mobile devices to find the neighboring APS, to disseminate short-term security associations with candidate APs and to perform short-term DHCP resource reservations in the networks served by candidate APs. With this approach, we are able to reduce the overall handover delay from thousands of microseconds down to a few microseconds, i.e. two orders of magnitude less.
