Abstract :
In this paper, we propose a solution for avoiding extensive time consuming path loss calibrations when performing RSS-to-distance conversions for indoor mobile positioning with heterogeneous mobiles. By exploiting RSS measurements and ad-hoc link communications we prove the concept of cooperative calibration and demonstrate it in a WLAN 802.11 network. Moreover the results obtained in the cooperative calibration phase will be applied to the cooperative mobile positioning algorithm developed in previous works.
