Abstract—Location-awareness of mobile objects is the key to numerous emerging ubiquitous computing applications. We show that RFID technology can be leveraged to achieve mobile object localization in an inexpensive, power efficient, scalable, widely applicable, flexible, and user-friendly manner. We outline the challenges that can adversely affect RFID-based localization techniques, and propose solutions to mitigate them. We present several algorithms for RFID-based mobile object localization that compare favorably or exceed previous methods in terms of accuracy, speed, reliability, scalability, and cost
