Within Skyline Query Processing in Dynamic Road Networks
The continuous within skyline query is an important type of location-based query, which can provide useful skyline object information for the user. Previous studies on processing the continuous within skyline query focus exclusively on a static road network, where the object attributes and the conditions of roads remain unchanged. However, in real-world applications, object attributes and road ...
متن کاملSkyline query processing
This thesis deals with a special subset of multi-dimensional set of points, called the Skyline. These points are the maxima or minima of the complete set and are of special interest for the field of decision support. Coming from basic algorithms for computing the Skyline we will develop ideas and algorithms for “on-the-fly” or online computation of the Skyline. We will also extend the concept o...
متن کاملDistributed Spatial Skyline Query Processing in Wireless Sensor Networks
Spatial skyline queries can be used in wireless sensor networks for collaborative positioning of multiple objects. However, designing a distributed spatial skyline algorithm in resource constrained wireless environments introduces several research challenges: how to distribute the computation of distances to multiple events in order to compute the skylines efficiently, accurately, quickly, prog...
متن کاملAnonymous Processing of Query in Road Networks
The increasing availability of location-aware mobile devices has given rise to a flurry of location-based services (LBS). Due to the nature of spatial queries, an LBS needs the user position in order to process her requests. On the other hand, revealing exact user locations to a (potentially untrusted) LBS may pinpoint their identities and breach their privacy. To address this issue, spatial an...
متن کاملMulti-Dimensional Skyline Query Processing
Introduction In many applications, a huge number of geometric, geographic or spatial objects are need to be stored, managed, and retrieved. As examples, some of the traditional applications are listed as follows: • Geographic Information Systems (GIS), which help users to organize their work in many areas, including military applications, environmental information systems, urban planning and so...
