Research of Indoor location based on BIM technology and Wireless sensor network

Indoor location; wireless sensor network; RSSI; BIM

In recent years, with the rapid development of society andthe economy, an increasing number of large buildings emerged, increasing the demand for positioning and navigation. this paper proposed a location method based on the RSSI and Inertial navigation technology.it calculated RSSI value through wireless signal strength between the nodes,then converted RSSI value into centroid algorithm weights and used centroid localization algorithm to calcauate the node location and associated with the coordinate of the BIM model, which realizes the indoor location of 3D visualization and obtained node exact location, this method improves the node location accuracy and reduces the location error compared with traditional indoor localization method.
