Path oracles for spatial networks
2009
Proceedings of the VLDB Endowment
The advent of location-based services has led to an increased demand for performing operations on spatial networks in real time. The challenge lies in being able to cast operations on spatial networks in terms of relational operators so that they can be performed in the context of a database. A linear-sized construct termed a path oracle is introduced that compactly encodes the n 2 shortest paths between every pair of vertices in a spatial network having n vertices thereby reducing each of the
