My main research interests are in the areas of communication network architectures, protocols, and applications, including system design, implementation and evaluation for computer networking, distributed systems and networked multimedia, with a focus on Quality of Service, signaling and reliability, performance evaluation and optimization, network security, mobile and wireless networking, application and system aspects for multimedia networking, and overlay and peer-to-peer networks.
Over the years, I have been extremely fortunate to be exposed to multiple projects and ideas from different researchers and collaborators at many institutions, would them of the academia or the industry from Germany, Europe or worldwide. Each of these experiences has either led to publications, standard specs and implementations, patents, and other forms of contributions to the community. These also resulted in a successfully secured funding for our networking research team currently comprising 1 postdoc, about 6 Ph.D. students and several master students. The group is committed to high quality research with the aim of ensuring that our contributions remain relevant to the changing needs of the community.
Among these efforts I recently helped to define and setup the EC FP6 IST ENABLE and MING-T research projects, in which I am serving on the Project Steering Committees. I am also leading the Goettingen team in the EC EUREKA Celtic VIDIOS project (also on its Project Coordination Committee) and participating in the EC FP6 IST Daidalos (Phase II) project. I have also been responsible for research collaboration projects with Siemens Corporate Technology (PTLS) and Panasonic Princeton Laboratory (MobiAuth). The research can be roughly categorized into the following 5 themes:
While so far I devote my energy mostly to IP-based wired, wireless and mobile communication networks and networked multimedia research, I envision networked systems that integrate technologies of efficient, reliable, secure and sustainable communications and computing, and moreover serve as, in many cases, a building block that interacts with other technologies such as sensing, middleware, GRID, content, and more. I look forward to the open research issues (and opportunities!) towards the seamless co-existence, interoperability, emerging applications and future architectures of network technologies, and I am happy to identify and address issues in other related directions, from the operating systems support, to distributed systems design and and service enabling technologies.
