In recent years, with the rapid development of mobile communication network, wireless network technology and pervasive computing, the demand of location-based service, especially indoor positioning, is becoming increasingly urgent. Indoor positioning based on Ultra wideband (UWB) is one of the most accurate indoor positioning technologies; however, due to its high cost, it is difficult to cover the large indoor environment completely. In view of the limitations of the existing indoor positioning technology, this paper designs and implements an indoor positioning algorithm and prototype system based on RFID, which could assist the existing indoor positioning based on UWB and reduce costs on the premise of positioning. Experiments show that the algorithm in this paper has better effect than other methods.
