Relative Localization of Wireless Sensor Nodes by Using the RSSI Data

Abstract

Wireless sensor network is an emerging research field and a crucial infrastructure for Internet of Things (IoT) applications. Sensor nodes of a wireless network may connect via different wireless technologies like Wi-Fi, Bluetooth, ZigBee or WiMAX. In many applications, like field monitoring or smart buildings, the location of the nodes with respect to a global or relative coordinate system is essential information. The main focus of this work is the localization of wireless sensor nodes, using the Received Signal Strength Indicator (RSSI) metric of the wireless telecommunication infrastructure. We present both simulation and measurement results of the proposed method and compare the results with similar work.
