Towards zero-configuration for Wi-Fi indoor positioning system

This paper describes the state of the art of indoor positioning. It describes the Wi-Fi auto-calibration phase of a fast and adaptive algorithm to calculate the position of access-points in a heterogeneous environment such as a building, house or flat. Our proposal can track a mobile terminal in a building with a minimum of preparation. This deployment simplicity relies on the auto-calibration phase. Of course, this service must also provide good positioning accuracy. Therefore, the auto-calibration function described in this paper has two advantages: it serves to initialize and to model the environment using a set of environment parameters that the operator, using the web interface, can confirm or change.
