This page describes my current research interests at University of Luxembourg as well as previous academic achievements from my Masters studies at Georgia Institute of Technology or engineering degree at Supelec.

Current research areas [top]

My current research focuses on developing communication protocols for ad hoc and delay tolerant networks, providing dynamic hence robust exchanges in everyday users interactions. Therefore, I investigate the evolution of community structures and other dynamic graph properties of those networks.

I also focus on social aspects of user interaction and behavior which I try to capture in realistic simulation models.

Node communities and human users interations in protocol design [top]

The following presentation presents SAw-SHARC (Stability Aware SHARC), an evolution of the SHARC algorithm that considers link stability as edge weight in the community assignment process. It was presented during the ERCIM SNA WG on Algorithmic Aspects of Social Network Analysis
