Layered Architecture for Mobility Models – LEMMA

We introduce a generic layered architecture that can be used to construct a wide variety of mobility models, including the majority of models used in wireless network simulations. Each mobility model is divided in five distinct layers that communicate via interfaces, thus allowing their easy replacement and recombination. We review 18 layers that can form 304 different mobility models. Additionally, we discuss how to aggregate some of the layers into new ones, and how to define hybrid and group mobility models. Numerous studies performed in various research fields (e.g. traffic engineering, crowd dynamics) turned out to be directly applicable to the different layers, which further supports the pertinence of our proposition.
