RESEARCH INTEREST

My research interest is the design and performance evaluation of distributed search methods focusing on applications of Peer-to-Peer(P2P) network protocols and security.

I am also interesting in the synergy between P2P and

1. Power management
2. Secure protocols in P2P using steganography for authentication
3. Wireless sensor networks for Structural Health Monitoring with Sun SPOT (Sun Small Programmable Object Technology) from Sun Microsystems Laboratories
4. Sharing expensive lab equipment (CyberLabNet)
5. Gaming (XBOX 360) traffic measurement and security.
