Computer Systems Modelling and Performance Evaluation Group

Systems Modelling and Performance Evaluation Group (SMaPEG) conducts research on models of computer systems and novel methods of modeling. In the scope of interests of the Group there are mainly models of computer networks. We are engaged in simulation and analytical modeling, both queuing models and other methods. Our experience embraces using of well-established modelling packages, like NS, OmNET++ or PRISM as well as creation of advanced proprietary software working in parallel environments.
