WirelessHART specification is emerging nowadays as a solution for the last mile connection in order to attend a trend on industrial networks that aims the usage of wireless technologies. Despite its high degree of applicability, a WirelessHART network faces some challenges. One of the most challenging problems are its reliability, energy consumption and the environment interference. Thus, representing a key component for the lower layers. In order to enable performance evaluations in a low cost and scalable way, computer simulations might be adopted. In this paper, we do a reliability and energy consumption evaluation over a faulty link industrial scenario using a new NS-3 module for the WirelessHART physical layer. This new model features includes an error model (Gilbert-Elliot), station positioning, signal attenuation and energy consumption. Furthermore, the module permits to configure each link with different fault probabilities, allowing to simulate more accurate scenarios.
