Systems: Design and Modeling

Our work is focused on modeling and designs of systems. The objective of modeling is to capture the system (dynamic) behaviors in the most accurate yet compact forms, so that they can be used for optimization of the system design and operation. Started from the stochastic modeling paradigm, our modeling work is expanded to real-time data based modeling paradigm using proper control theories, and signal processing techniques. We are particularly interested in attacking issues that require cross cutting solution techniques, where high level behaviors would be characterized by stochastic models and low level features would be captured by multi-resolution filtering techniques.

System design spans a wide range of topics. We are working on topics in the aeras of

• networking (bandwidth provision, network localization, locality aware object locating, DOS defense, anomalous traffic detector),
• distributed systems (anonymous and accountable collaboration, secret location services, confidential auditing),
• processor architecture (configurable computing architectures, real time utilization bound).
