Deploying sensor networks in an efficient and optimal way has become an important topic these days. A sensor network is basically an infrastructure which consists on number of nodes equipped with a sensor, a controller and a communication module. Interference from the neighboring nodes makes it difficult for a communication system to achieve the required throughput and also makes it difficult to predict the network behavior. CupCarbon is a wireless sensor network (WSN) simulator, recently developed by researchers of Lab STICC, for a better analysis and understanding of WSN. In this paper, we present an optimal way to integrate a PHY layer based on Orthogonal Frequency Division Multiplexing (OFDM) in the simulator and we have also considered the network interference impact in wireless communication. For a flexible and accurate representation, interference is modeled by alpha-stable distribution function. This allows the better estimation of channel conditions to take into account the channel conditions and the density of interferers in a network.
