Radio Frequency Identification (RFID) is a technology that can be applied to track people and objects. In this paper, RFID passive tag-based indoor localization is utilized. Cost-effective and low power consumption system are the advantages. Simulation of the fingerprint-based localization technique in indoor environment using the Dot Product is applied. This algorithm is used to find the estimated location by multiplying the row vector of all fingerprint locations with the row vector of the observed location. Then, the location of the target will be the fingerprint location providing the maximum value of these dot products. The norm equation is used to find the error distance. The average error of this proposed method is approximately 14cm. We can get conclusion that our proposed method can be applied in real application.
