Research

I wrote my MSc. thesis on TCP in wireless environments and wireless link emulation. My PhD. work was about IP mobility and Quality of Service. This is still an important area for me, e.g., through my work in the IETF NSIS and TSVWG working groups.

Lately I have moved into ad-hoc networking, IP session management, and especially network security. After all, even when you design a great network protocol or architecture, if you can't make it secure, you won't gain much deployment for the benefit of the society. Thus, security must be a key design aspect from the very beginning.

  My research interests

• Network security, focus on security of IP-based protocols and architectures
• IP QoS, mobility, and session management
• Quality of service in future mobile networks
• Wireless and mobile communications (WLAN, WWAN, ad-hoc, etc.)
• Distributed systems
• Linux as a platform for software engineering
• Transport protocols and their performance
