Tactical AD HOC Scenarios Generator Coupled with Channel Modeling

Simulation tools are very helpful for cost-effective design of wireless networks and useful to have better understanding of many phenomena. Ad hoc networks are one of the complex wireless systems because of the difficult to have good prediction in their topology changing. Our contribution in this paper is to provide as well as possible the best description of ad hoc scenarios in order to have a better analysis of the physical layer, and finally to improve performances of the whole network. We have created a scenarios generator to be able to generate a large number of scenarios with the same set of parameters or various scenarios. To meet some requirements of military use (which is our main application) we have proposed improvements of some classic mobility models. Many figures are depicted to illustrate our approach. And finally, we present the results in term of channel behaviour while coupling the generator with a semi-deterministic propagation model.
