Abstract—In wireless communication system, one of the unique challenges is mobile asset tracking and localization and becomes an important in the deployment of wireless enabled products. Spatial information of mobile assets is an important feature in assets management system that allows owners to gain real time insight of inventories. To meet this challenge, we developed a simple, low cost, and reliable tracking and localization system using ZibBee technology. This paper implementing a method of positioning using a Received Signal Strength Indicator (RSSI) concept. Each target asset is tagged with the blind ZigBee node and known fixed positional ZigBee nodes are used to track their positions. The RSSI values between the blind nodes and the fixed nodes are converted to the distance providing the basis for using the trilateration methods for location estimation. We also developed a software written in C# that used to solve the trilateration problem and the final results of trilateration methods are mapped using Google maps. In this project, measurement and simulation were implemented and provide agreement around 89% to 92%. The outcome of this study can extend current asset management functionality by providing positioning capabilities without using a positioning hardware such as the Global Positioning System (GPS), and making it suitable for a low cost deployment.
Index Terms—Mobile asset positioning, real time location system (RTLS), trilateration.
