Kurzbeschreibung (Abstract)
Wireless Indoor localization systems based on RSSI-values typically consist of an offline training phase and online position determination phase. During the offline phase, georeferenced RSSI measurement, called fingerprints, are recorded to build a radiomap of the building. This radiomap is then searched during the position determination phase to estimate another nodes location. Usually the radiomap is build manually, either by users pin-pointing their location on a ready-made floorplan or by moving in pre-specified patterns while scanning the network for RSSI values. This cumbersome process leads to inaccuracies in the radiomap. Here, we propose a system to build the indoor- and radio map simultaneously by using a handheld mapping system employing a laser scanner in an IEEE802.15.4-compatible network. This makes indoor- and radio-mapping for wireless localization less cumbersome, faster and more reliable.
