| Popis: | This study explores the indoor positioning in wireless networks. We used the Minimum Mean Square Error (MMSE) algorithm for triangulation positioning with the received signal strength (RSS). Through previous research, it is found that the accuracy of positioning is not only related to the distance between the reference point and the positioning node, but also the variation of the distance between the reference point and the positioning node. It also affects the accuracy. Therefore, considering the distance between the reference point and the positioning node, and the distance variation between the reference points, it is divided into the internal distance variation (IDV) and the external distance variation (EDV). We proposed a reference nodes selection (RNS) with the weighted variation mechanism. Simulation results show that the effective reference improvement can be obtained by the weighting RNS method of the EDV. |
