A two-level social mobility model for trace generation

We propose a synthetic trace generator that, although based on a simple mobility model, generates traces with statistical properties (like inter-contact time and contact duration) resembling those of well-known real traces. The proposed model is based on a waypoint scheme, with some modifications: the introduction of two categories of nodes, steady and nomadic, with different mobility rates; the grouping of nodes in communities sharing the same location preferences, and the definition of a micro-mobility model inside each location. The statistical properties of the traces generated with this model are compared to those obtained from publicly available real traces.
