Abstract
Propagation prediction algorithms which use terrain information
are typically used for the design of modern wireless systems.
Therefore, it is essential that when analyzing the performances of
ad hoc networks we observe the network in a natural 3D terrain
and we use an appropriate propagation model. In this paper we
explain our extension of the NS-2 simulator using Digital
Elevation Model data and terrain aware propagation model.
Because of the natural emergence of clustering in the network of
users, we also study the relationship between the clustering in the
ad hoc networks and different terrain profiles. The simulations
show that, when the network clusters are accompanied with
related terrain contours, the observed network performances
demonstrate measurable enhancement.
