In the past decade, probabilistic nearest neighbor (PNN) query processing has received significant research attention due to the development of mobile smart terminals and the advances in wireless communication technologies. However, to the best of our knowledge, most of the existing PNN-oriented studies are aimed at the Euclidean space and cannot be readily extended to road networks. This paper takes...
In many applications like moving-objects and sensors databases, data values are inherently uncertain. In these systems, an attribute value can be modeled as a range of possible values, associated with a probability density function. Data mining of the uncertain data attracts more and more research interest recently. The definitions of probabilistic core object and probabilistic density-reachability...
With the increasing popularity of wireless sensor network and GPS technologies, uncertain data as a new type of data bring new challenge for the data processing methods. Data broadcasting is an effective means for data dissemination in mobile computing environment. Definition of the mean uncertainty ratio of data is presented and a broadcasting scheme UDBS is proposed for uncertain data dissemination...
