Seminario: "Cognition-based Systems: from Wireless Networks to Healthcare", 25 Marzo 2015 ore 10.00

The cognition-based approach is exploited in a scenario where two wireless ad hoc networks are willing to share some of their nodes, acting as relays, in order to gain benefits in terms of lower packet delivery delay and reduced loss probability. The selection of the nodes to share is made by means of a game theoretic approach, which exploits Bayesian network learning. We show that an accurate selection of the shared nodes can significantly increase the performance gain with respect to a random selection scheme.
In the second part of the talk, we show that the cognition-based approach is not limited to networking problems. It can also be applied to a wireless sensing system, which integrates physiological data collection, analysis, visualization, and biofeedback. We analyze a case of study, with a group of people performing a group activity. We show how the analysis of physiological signals can reveal interesting insights into real-time autonomic influences on the functioning of the human body. The seamless collection of these signals can open an important research opportunity.

From 25/03/2015-10.00 to 25/03/2015-10.00 , IIT - Aula A32

Speaker: Giorgio Quer

Responsible: Maria Elena Renda

Note: Dr. Giorgio Quer received a B.Sc. (2005) and an M.Sc. with honors (2007), both in Telecommunications Engineering, from the University of Padova, Italy. He later earned a Ph.D. (2011) in Information Engineering from the same institution. In 2007, Giorgio was a visiting researcher at the Centre for Wireless Communication at the University of Oulu, Finland, where he performed research on forwarding and routing techniques for wireless sensor networks. During his doctoral studies, Giorgio's research has been focused on wireless networks optimization, in collaboration with DOCOMO Euro-Labs, Munich, Germany. In 2010, Giorgio joined UC San Diego's Calit2 as a visiting scholar, working on learning techniques for cognitive networks within the military-funded ARO-CogNet project. Since 2011, Giorgio has been a postdoctoral researcher at UCSD. He currently serves as a reviewer for several IEEE and ACM journals. Giorgio's research interests include wireless sensor networks, compressive sensing, wireless network optimization, cognitive networking, Bayesian analysis, signal processing, and wireless health.
