The event-driven network simulation platforms, e.g. NS2 and GloMoSim, adopt some general wireless channel propagation models providing the pathloss of the channel as well as the SNR of each received packet to estimate the BER. However, these SNR-based general channel models give more accurate results for outdoor environments than indoor. On the other hand, the SIRCIM is a well-established channel impulse response based indoor channel model taking different indoor situations into consideration. This paper presents a method that integrates the SIRCIM model into the simulation platforms using SNR-based model by converting the channel impulse response of the SIRCIM into the pathloss. This conversion provides not only a more precise SNR-based indoor channel model but also the inter-symbol-interference information to achieve a more accurate BER estimation for simulating the indoor networks such as wireless sensor networks and wireless personal area networks.
