碩士 === 高苑科技大學 === 資訊科技應用研究所 === 102 === With the fast advance of positioning techniques, spatio-temporal databases aiming at managing moving objects so as to provide useful information has attracted a lot attention. In real world, there are many applications related to spatio-temporal queries, such as geographic information, traffic monitoring system, and mobile information system. Skyline query is an important type of spatio-temporal queries. In this thesis, we focus on how to apply the skyline query to sensor network environment. Different form the previous research, in the sensor network environment, the positioning technique used is not the GPS technique, but is the sensor network technique. This results in a greater positioning error. In this thesis, we will try to manage the moving objects with uncertain location information. With the location information, we will design query algorithm to process the skyline queries. Benefiting from the developed query system, we can efficiently manage the moving objects and thus provide useful information to the user.
