Towards Increasingly Update Efficient Moving-Object Indexing

Current moving-object indexing concentrates on point-objects capable of continuous movement in one-, two-, and three-dimensional Euclidean spaces, and most approaches are based on well-known, conventional spatial indices. Approaches that aim at indexing the current and anticipated future positions of moving objects generally must contend with very large update loads because of the agility of th...

Boosting Moving Object Indexing through Velocity Partitioning

There have been intense research interests in moving object indexing in the past decade. However, existing work did not exploit the important property of skewed velocity distributions. In many real world scenarios, objects travel predominantly along only a few directions. Examples include vehicles on road networks, flights, people walking on the streets, etc. The search space for a query is hea...

Efficient Update Method for Indexing Locations of Moving Objects

Tracking the changing positions of moving objects is becoming increasingly feasible and necessary. However, traditional spatial index structures are not suitable for storing these positions because of numerous update operations. In this paper, we propose an efficient update method for indexing the locations of moving objects based on the R-tree. This technique updates the structure of the index...

Update-efficient Indexing of Moving Objects in Road Networks

Recent advances in wireless sensor networks and positioning technologies have boosted new applications that manage moving objects. In such applications, a dynamic index is often built to expedite evaluation of spatial queries. However, development of efficient indexes is a challenge due to frequent object movement. In this paper, we propose a new update-efficient index method for moving objects...

Novel Approaches to the Indexing of Moving Object Trajectories

The domain of spatiotemporal applications is a treasure trove of new types of data and queries. However, work in this area is guided by related research from the spatial and temporal domains, so far, with little attention towards the true nature of spatiotemporal phenomena. In this work, the focus is on a spatiotemporal sub-domain, namely the trajectories of moving point objects. We present new...
