An Improved Indoor Positioning Method Based on Nearest Neighbor Interpolation

Nowadays, people’s demand for indoor location information is more and more, which continuously promotes the development of positioning technology. In field positioning, fingerprint based algorithm still accounts a large proportion. However, operation this method in offline stage too cumbersome time-consuming, makes its disadvantages obvious, requires lot manpower time to sample maintain. Therefore, view phenomenon, an improved on nearest neighbor interpolation designed paper, reduces measurement actual sampling points when establishing map. At same time, some simulation are added expand map, so as ensure that error will not become larger or even better. Experimental results show can further improve accuracy while saving cost.
