David Sánchez Josep Vidal Multidisciplinaria (Ciencias Naturales y Exactas) WLLS NLOS mitigation geometrical restrictions wireless sensor networks TOA based positioning systems This paper studies the Non-Line-Of-Sight condition mitigation issue in mobile subscriber positioning systems by weighting Time-Of-Arrival measures and applying geometrical restrictions. Particularly, this work departs from a more exact characterization of the signal statistics to achieve weighting factors able to reach a more effective mitigation, and consequently a more accurate mobile subscriber positioning. In addition, restrictions based on the cell geometry are incorporated as a complementary refinement method. Therefore, three new methods with better properties than those taken from the literature and used as reference are introduced. These approaches are evaluated within a realistic simulation scenario. 2015 artículo científico 1390-5384 https://www.redalyc.org/articulo.oa?id=726180880022 en http://www.redalyc.org/revista.oa?id=7261 Avances en Ciencias e Ingenierías application/pdf Universidad San Francisco de Quito Avances en Ciencias e Ingenierías (Ecuador) Num.2 Vol.7 |
