Study of received signal strength indication in ZigBee location cluster for indoor localization

This work focuses on the properties of received signal strength indication (RSSI) of ZigBee wireless sensor network, which can be used to implement indoor location system. The study collects a set of measurement samples in a closed room from an implementation of indoor localization application based on ZigBee Cluster Library (ZCL) framework. The measurement data are analyzed for their statistical parameters. The results are compared with the known properties of RSSI of wireless local area network reported in the literature. The insight of RSSI's properties obtained in this work could be used to improve the localization application using ZigBee wireless sensor network.
