Ad hoc networks simulations with real 3D terrains

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.
