The GI Research Seminar will address the following topics:
(please send us further topics, if you think that they should definitely be discussed):

1. Basics and Experiences of/with Network Simulation

   1. Introduction and Overview

      • Event-based simulation

      • Overview of simulation tools (capabilities, drawbacks, ease of use, ...)

      • Experiences with simulation in the area of communication

   2. State of the art and requirements in the area of network research

   3. Introduction to modeling

      • General definition of models and how they relate to simulations
      • Important steps during model creation
      • Models in computer science and other science domains
        

2. General modeling framework for network simulation

   • What is a general modeling framework?

   • Examples from other areas of research for modeling techniques

   • Requirements of a general modeling framework

   • Requirements of reference models for network research

3. Aspects of a network system which can be modeled or rather simulated.

   The first 2/3 of each of the following chapters should present the current state of research and the usual practice in the respective area, e.g. give a state-of-the-overview on modeling topologies, which tools are known and in use, and discuss the level of realism of these models. Furthermore, the last third of each sub chapter should deal with problems, requirements and possible solutions. The focus should be put on the question how this topic and its solutions can be integrated into a generic simulation framework. We expect about 15 sub chapters from the following areas (list will be extended):
