Mobility models are widely used in the simulation-based performance
analysis of mobile networks. However, there is a trade-off between
simple parametrization and realistic movement patterns. Synthetic
models like the random waypoint and random direction model are
simple to implement, but they only provide unrealistic simple user
sojourn densities and traffic flows. In contrast, graph- or
trip-based mobility models are complex to parameterize and their
results are difficult to compare. In this paper, we propose the
location-dependent parameterization of the random direction model to
fill this gap. This model extension allows to setup non-homogeneous
mobility scenarios, in particular based on real-world traces, while
it still belongs to the class of synthetic random walk mobility
models. We show that the location-dependent parametrization can
accurately model arbitrary mobility patterns with very limited
implementation complexity.
