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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
