Résumé : The adoption of new protocols and network mechanisms requires an experimentation phase which is complex to deploy, and even more on wireless networks. Generally, ad-hoc tools are developed for the specific needs on a experimental scenario to capture, analize and store statistical data. Because there is no common experimental methodology within the research community, and research publications do not provide often the experimental conditions, it is almost impossible for another researcher to reproduce the same experimental scenario. Within this research report, we define a network evaluation methodology to simplify the deployment of wireless experiments and their analysis. The proposed method uses a modular approach for the different experimentation phases. We also illustrate this methodology by an example.
