Spatial queries are becoming integral part of many mobile applications. With revolutions in GPS and GIS, the location based spatial queries are exploring spadal information to mobile users to a large extent. Finding nearest neighbor, shortest path to the destination, retrieving skyline objects and spatial skyline keyword query are some of commonly used queries on road networks. In this paper we introduce a new query type called Boolean Skyline Boundary (BSB) query on road networks. The algorithm retrieves the BSB objects based on both network distance and travel time on road networks. The algorithm searches the objects based on user specified spatial boundary and the Boolean skyline expression. The algorithm also specifies the shortest path to reach the BSB objects. The experimental evaluation reflects the performance of BSB algorithm.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
