There is a need for agent oriented software engineering methodologies that support the conceptual modeling of mobile-agents systems. For this reason, we have presented in a previous work, our meta-model to design multi-agents systems including mobile agents and we have discussed it versus some formalisms extending UML for mobile-agents modeling. The proposed meta-model serves as a platform independent meta-model in our model-driven engineering approach under elaboration as a methodology for the development of multi-agents systems including mobile-agents. This paper summarizes the different approaches for mobileagent modeling and situates our meta-model particularly versus three works supporting mobility by extending a multi-agents systems methodology (MaSE, GAIA, and AALAADIN). It aims to justify the choices that have guided our meta-model construction.
