Generic simulation models of communication systems

One of the most significant criticisms on traditional simulation modeling has been the lack of reusability. However, the cost of using simulation technology can be reduced through the extensive application of model reusability. We address the question of reusability by showing how to create, in a generic way, models of complex communication network components from a library of basic models. These reusable units model network elements, such as buses, protocols, bridges, satellite repeaters, etc. We focus on how to enhance this library by deriving benefit from the reusability aspects of basic models. The Generic Models (GeMs) represent an adequate solution to notably enrich the library. They will be constructed by the modelers who have to respect certain constraints depicted in this paper. These constraints are related to the modeled domain which is the communication system.
