The general architecture of a simulator of wireless sensor networks and a detailed model of a wireless communications channel that involves various models of the radio-wave propagation are presented. It is demonstrated that the model of the radio-wave propagation significantly affects the connectivity of the wireless sensor network. It is shown that the radio-wave-propagation model based on the parabolic-equation method yields more accurate results for the packet reception rate as a function of distance and the width of the transition region. The results are in good agreement with experimental data, thus indicating that the effective and reliable simulation of a wireless communications channel can be implemented in practice.
