The advancement of location-based services now covers indoor location positioning. Under disaster in the building, the sufferer might faint, be wounded, or enclosed by structures in the dark. In the cases, the sufferer could not let the relief team know her position in the building. The LBS server provides location tracking or positioning of her device for quick relief. In the service UltraWideBand is used by its good penetrability. In dead-reckoning operation that the device is lost on the sensor network, the relief team traces logged profiles of location tracks. The strategy regards the privacy concerns. © 2009 ICST Institute for Computer Sciences, Social-Informatics and Telecommunications Engineering.
