Abstract

This paper investigates the possibility of implementing node positioning in the ZigBee wireless sensor network by using a readily available Received Signal Strength Indicator (RSSI) infrastructure provided by the physical layer of 802.15.4 networks. In this study the RSSI is converted to the distance providing the basis for using the trilateration methods for location estimation. The software written in C# is used to solve the trilateration problem and the final results of trilateration methods are mapped using Google maps. Providing node positioning capability to the ZigBee network offers an enormous benefit to the Wireless Sensor Networks applications, possibly extending the functionality of existing software solution to include node tracking and monitoring without an additional hardware investment.
