| Summary: | 碩士 === 元智大學 === 電機工程學系 === 103 === GPS is a popular locating approach. However it cannot be used in indoor environment. Different signal resources, such as Bluetooth 4.0 and Wi-Fi, are necessary in indoor environment. Wi-Fi is a promising tool because many buildings had constructed Wi-Fi Access Point(AP) already. In this research, we consider the positioning of indoors basing on information of background signals acquired from users. Our scheme Indoor AP Positioning(IAP) is composed by two steps: (1) Centrifugal Direction(CD) for outdoor signal. (2) Multidimensional Scaling(MDS) for indoor signal. Then, we combine two methods and produce the final results. The results of IAP is better than others.
