Abstract EN
Recently, Bluetooth-based indoor positioning has become a hot research topic.
However, the instability of Bluetooth RSSI (Received Signal Strength Indicator) promotes a huge challenge in localization accuracy.
To improve the localization accuracy, this paper measures the distance of RSSI vectors on their low-dimensional manifold and proposes a novel positioning method IWKNN (Isomap-based Weighted K -Nearest Neighbor).
The proposed method firstly uses Isomap to generate low-dimensional embedding for RSSI vectors.
Then, the distance of two given RSSI vectors is measured by Euclidean distance of their low-dimensional embeddings.
Finally, the position is calculated by WKNN.
Experiment indicates that the proposed approach is more robust and accurate.
