Mobility models have traditionally been tailored to specific application domains such as human, military, or ad hoc transportation scenarios. This tailored approach often renders a mobility model useless when the application domain changes. Furthermore, the failure to adapt the mobility model to accurately match the new domain naturally leads to wrong conclusions about the performance of protocols and applications running atop. In this paper, we propose a mobility modeling framework based on

We have designed and implemented a Universal Mobility Modeling Framework (UMMF), which enables the instantiation of a mobility model from a wide universe of possibilities defined by the aforementioned factors. We describe the mapping from application-domain-specifics to UMMF elements, demonstrating the power and flexibility of our approach by capturing representative mobility models with good accuracy in terms of a large number of topological metrics. We also describe several specific mobility scenarios and their UMMFbased model representations.
