Spatial boolean skyline boundary queries in road networks

Abstract

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.

“…To sum up we make the following contributions: 1) Developed an algorithm for blocking SMS based on keyword, date-wise, time-wise and location-wise. [6], [7], [8], [9], [10], [11] are gaining popularity with millions of users accessing goe-spatial points from anywhere and at anytime. Location-based services [12] offer users to connect with friends, to discover their environment or to optimize their mobility.…”
