Welcome

Ralph Lange

Hello! I'm very pleased that you are visiting my website.

My name is Ralph Lange and I am about to finish my PhD thesis in computer science at the , Germany, in 2010.

I received my Diplom (≈ MSc) with distinction in computer science from the same university in 2005. Since then, I have been a research staff member of the and have been working within the .

Research Interests

Distributed systems

Pervasive/context-aware computing

Scalable location management
