碩士 === 國立臺灣科技大學 === 工業管理系 === 95 === Location is one of the contextual variables most relevant to the design of context-aware computing systems. These application need to know the physical location of users in order to provide information relevant to their position. Radiofrequency signals received by mobile devices can be measured to obtain signal strength. These signals can be used to estimate the approximate location of a user. We present a WLAN indoor location determination approach using BPN+SA and enclosing circle. The BPN+SA can provide suitable results of estimation and make the better network architectures and parameters which result in a better classification. The enclosing circle can make the results more precisely. So the proposed approach can be considered as a compatible location estimation system.
