Simulation of heterogeneous networks

This paper presents a simulation tool to help the network designer to identify the optimum network design parameters for a heterogeneous network environment. The tool consists of two parts: simulation modules and a user interface. The simulation modules are created using enhancements of an asynchronous, event-driven C-function library to enable the simulation of heterogeneous scenarios. In the future, this module will be distributed to speed-up the simulation runtime. The user interface helps the user to create the design of the network to be simulated. By this modular concept of distributed simulation modules and user interface the optimum network can be found out without much knowledge of the underlying simulation details.
