Convex polygon positioning for homogeneous optical wireless networks

Résumé

In this paper we present a novel range free method based on connectivity for homogeneous optical wireless networks. Optical attocells deployed homogeneously within an indoor scenario send periodically its position and network architecture information. The mobile node (MN) uses this information in order to self-determine its position by means of solving different convex optimization problems. As a result of this procedure, the feasible localization area is reduced to a convex polygon. A square room of 2.4 meters width and 2.4 meters large with 9 LED lights placed in the ceiling is modeled as the proposed scenario. Our method is compared with two connectivity-based range free algorithms in terms of accuracy. In addition to this, robustness of the method is evaluated using different values on the receiver's Field of View (FOV). Numerical results show that the proposed method outperforms the connectivity based methods in terms of accuracy and robustness.
