	abstract = {Almost all work on mobile ad hoc networks relies on simulations,
which, in turn, rely on realistic movement models
for their credibility. Since there is a total absence of realistic
data in the public domain, synthetic models for movement
pattern generation must be used and the most widely
used models are currently very simplistic, the focus being
ease of implementation rather than soundness of foundation.
Whilst it would be preferable to have models that better reflect
the movement of real users, it is currently impossible to
validate any movement model against real data. However,
it is lazy to conclude from this that all models are equally
likely to be invalid so any will do.
We note that movement is strongly affected by the needs
of humans to socialise in one form or another. Fortunately,
humans are known to associate in particular ways that can
be mathematically modelled, and that are likely to bias their
movement patterns. Thus, we propose a new mobility model
that is founded on social network theory, because this has
empirically been shown to be useful as a means of describing
human relationships. In particular, the model allows
collections of hosts to be grouped together in a way that
is based on social relationships among the individuals. This
grouping is only then mapped to a topographical space, with
topography biased by the strength of social ties.
We discuss the implementation of this mobility model and
we evaluate emergent properties of the generated networks.
In particular, we show that grouping mechanism strongly
influences the probability distribution of the average degree
(i.e., the average number of neighbours of a host) in the
simulated network.},
