Holographic Multi-Reader RFID Localization Method for Static Tags

With the development of communication technology, the internet of things and the rapid augment of their applications and services, the demand for indoor localization is increasing. RFID based indoor localization system is a good solution for these applications and services. However, due to the complex multi-path interference of indoor environment, most of the localization methods have a low positioning accuracy. In this paper, we present an enhanced holographic RFID localization method for static tags in indoor environment by using four moving RFID readers. The obtained results show the power of our proposed method in term of positioning accuracy for wide localization area.
