Abstract

Location update strategy is one of the most important factors that affect the performance of moving objects databases. In this paper, a new location update mechanism, Location Update Mechanism for Network-Constrained Moving Objects (Net-LUM), is proposed. Through active-motion-vector-based network-matching and special treatment with junctions, Net-LUM can achieve better performances in terms of communication costs and location tracking accuracy, which is confirmed by the experimental results.
