Abstract
The network simulator ns-2 implements both wireless networks and emulation — a feature that allows to simulate a network environment among real stations. In contrast to a discrete event simulation an emulation is affected by various system parameters. The understanding of the impact of those parameters is crucial to obtain valid results from an emulation experiment. In this paper we evaluate a modified version of the ns-2 that has been optimized for emulations. We analyze the effect of different parameter settings in various experiments and compare the results with measurements in a live network.
