Abstract
Some of the most important application
domains for ad hoc networks are battlefield communication,
rescue missions and homeland security. All of these outdoor
applications are places onto real, irregular terrains. Node
placement over the terrain and radio signal fluctuation can
degrade the quality of the radio links, which is why the
terrain profile should be taken into consideration during
simulation and estimation of the signal losses. In this paper
we present a newly implemented Fresnel zones propagation
model extension for the NS-2 network simulator for the
purposes of simulating realistic network scenarios.
