STEPS mobility model

STEPS is a simple parametric model which can cover a large spectrum of human mobility patterns

Spatio-TEmporal Parametric Stepping (STEPS) makes abstraction of spatio-temporal preferences in human mobility by using a power law to rule the nodes movement. Nodes in STEPS have referential attachment to favorite locations where they spend most of their time. STEPS is able not only to express the peer to peer properties such as inter-contact/contact time but also to express the structural properties of the underlying interaction graph such as small-world phenomenon.

For the further details of STEPS, please refer to the paper:

The zip file contains an example which shows how to use STEPS. To get started, you can change some variables in simulation_example.m and run simulation_example(1). An animation will be launched and allows you to have an idea of how it works.
