In this paper, experimental measurements of the received signal strength in a smart home test bed are presented. The measurements are used to develop a topology-independent probabilistic indoor path loss model. The proposed path loss model adds a random loss component to the log-distance path loss model to account for wall penetration, reflection, scattering, and diffraction effects. The proposed model is incorporated into the network simulator ns-3 to simulate IEEE 802.11 and IEEE 802.15.4 networks. Our results indicate that the throughput of both networks degrades as the density of the nodes increases due to increasing the connectivity of the interference links.
