Comparing ray tracing, free space path loss and logarithmic distance path loss models in success of indoor localization with RSSI

In this paper, free space path loss, ray tracing with one and two reflection points and logarithmic distance path loss models are used to determine distance between nodes according to RSSI values. First of all, required parameters to use called models are determined by making RSSI characterization study in corridors. Then determined parameters are used to perform a localization test RSSI characterization and localization tests are carried out for different areas and environments´ effects and success of all models are investigated.
