A localization and position tracking solution utilizing solar-powered RFID tags

The ability to determine the position of a device in outdoor or indoor environments is becoming the foundation for an ever increasing number of a diverse set of services. This paper demonstrates the implementation of a very low-cost localization and device tracking system on top of a Wireless Sensor Network (WSN) topology. Its major components, namely the mobile RFID prototype, the fixed wireless infrastructure and the central server, are described and an initial evaluation of the accuracy of the system is presented.
