Performance Analysis of Telecommunication Systems

Research

History

The Performance Analysis of Telecommunication Systems (PATS) research group is part of the Department of Mathematics and Computer Science of the Faculty of Science of the University of Antwerp. The group was founded in 1995. It is one of the members of the Future Internet Department of iMinds (formerly IBBT), an independent research institute founded by the Flemish government to stimulate ICT innovation. PATS performs basic, applied and contract research related to the performance analysis of telecommunication systems and the impact of performance on the architecture and the design of these systems.

Activities

Recent technological key advances in telecommunications, such as broadband local access (bringing broadband to the home by DSL, cable and fibre), mobile communications (like GSM, UMTS, LTE and Wireless LAN allowing connectivity anywhere and anytime) have been made possible, among others, by the results of research on new, highly flexible network architectures, protocols and applications. The rate at which new technological solutions are produced has never been higher than today, just refer to sensor networks, the internet of things, the application of ICT in the health sector, the connected car, etc... Moreover, the performance of these technologies is one of the major characteristics that determine their economical success. These are exactly the technologies the PATS research group is addressing.

Our research can be structured into 3 research lines:

• Stochastic Modeling: This research lines deals with the development and application of stochastic modeling techniques to evaluate complex systems and communication systems in particular.
• Design and Analysis of Protocols and Algorithms for Networks: This research line addresses the design, analysis and implementation of algorithms and protocols for networks, where the primary concern is the system’s performance.
• Adaptive- and Dependable Systems: This research line deals with the design, development, and evaluation of techniques and models to structure computer and communication systems as adaptive systems able to constantly re-optimize in view of changes.
