Alfredo Grieco is going to present our new paper on 'A Frequency Domain Model to
Predict the Estimation Accuracy of Packet Sampling' at the MiniConference
of IEEE Infocom in San Diego, March 2010. It is a follow-up of our paper in IMC
2009.
"Revisiting content sharing in wireless ad hoc networks",
to be presented at the fourth workshop on self-organizing systems (IWSOS),
Zurich, December 2009.
Another paper on BitHoc
with Karim and Emna, "P2P content sharing in
spontaneous multi-hop wireless networks”, to be presented at the IEEE
COMSNETS conference, Bengalore, January 2010.
I am a permanent research scientist in the Planète project-team at INRIA, Research Centre Sophia Antipolis – Méditerranée, since March 2002. I got my Electrical and Electronics engineering degree from the Lebanese University of Beirut in 1997, and my Master and Ph.D. degrees in Networking from the University of Nice - Sophia Antipolis in 1998 and 2001. My Ph.D. was done in the Mistral project-team at INRIA Sophia Antipolis under the direction of Eitan Altman. From April 2001 to March 2002, I was with the LCA department at EPFL-Lausanne for a post-doctoral position (with a grant from Sprint Labs), and from March to August 2004 I was a visiting faculty member at Intel Research Cambridge working in the group of Christophe Diot on traffic monitoring. My main research interests are Internet measurement and traffic analysis, the TCP protocol, Peer-to-Peer networks (namely Bittorrent), modelling and performance evaluation of communication networks, Delay Tolerant Networks and data collection.
