In this paper, a novel 3D-based network simulation platform for wireless indoor networks is proposed. The purpose of the platform is to improve the accuracy of radio propagation modeling and to offer designers a virtual workspace for testing their systems. Radio propagation models are investigated by performing path-loss calculations and Fresnel zone geometry estimation in a research laboratory environment. This paper is an extended version of the authors' conference paper containing additional back-round information, extended testing and a more comprehensive explanation of the proposed simulation environment. Sensor networks are comprised of small wireless devices capable of sensing their environment and dynamically communicating with their neighbors.
