Traditional location-based services recommend nearest objects to the user by considering their spatial proximity. However, an object not only has its distance but also has its dir...
The result of a distance join operation on two sets of objects R, S on a spatial network G is a set P of object pairs <p, q>, p R, q S such that the distance of an object ...
Abstract— Wireless sensor networks (WSNs) promise finegrain monitoring in a wide variety of applications, which require dense sensor nodes deployment. Due to high density of nod...
