Mobility models are widely used in simulation-based performance
analyses of mobile networks. However, there is a trade-off between
simplicity and realistic movement patterns. Synthetic models like
the random waypoint and random direction model are simple to
implement, but only provide unrealistic simple user sojourn
densities and traffic flows. In contrast, graph and 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.
