With this paper, we explain a simulation environment for the popular area of Wireless-LAN-based indoor positioning based on free software. Using GNU Octave and typical radio propagation models, this open source indoor localization environment allows one to develop, analyze, understand and teach indoor positioning algorithms based on CAD-plans. The toolkit allows for calculating complex Wireless-LAN propagation maps, generate sequences of measurements following paths drawn in CAD, generation of room-based or coordinate-based fingerprinting databases as well as statistical analysis including the effect of noise on positioning accurarcy and precision. Furthermore some extraordinary simple data formats are proposed to facilitate exchange between indoor localization researchers and to support the collection of measurements for the indoor positioning community.
