Amir Krifa
defended his PhD in April 2012 on Content Dissemination in Delay Tolerant
Networks. Here is a copy of his manuscript.
Biography
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 working in the group of Patrick Thiran), 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 measurements and traffic analysis, the TCP protocol, content-centric and delay-tolerant networking, Peer-to-Peer networks (namely Bittorrent), performance evaluation of computer networks, wireless networks and data collection. I am senior member of the IEEE and member of the ACM.
Awards
- Best paper award for my paper “Optimal Buffer Management Policies for Delay Tolerant Networks”, IEEE SECON conference, San Francisco, June 2008 (Certificate).
- Best PhD student paper award for my paper “On ACK filtering on a slow reverse channel”, first international workshop on Quality of future Internet Services, Berlin, September 2000 (Certificate).
- Hariri foundation award, top 100 funded by the foundation in Lebanon and abroad, five times from 1993 to 1997.
