Enabling advanced simulation scenarios with new software engineering techniques.

In this paper, we introduce new techniques in the field of simulation to help in the process of building advanced simulation scenarios using preexisting simulation components. The first technique consists in using the Aspect Oriented Programming paradigm to capture some of the private data of an existing model component. The second one is an Architecture Description Language (ADL) designed for the Fractal component model, that offers definition overloading and extension mechanisms similar to those found in traditional Object Oriented languages.The benefits of using both techniques are illustrated by simple use cases of network security studies.
