Searching for Similar Trajectories on Road Networks Using Spatio-temporal Similarity
In order to search similar moving object trajectories, the previously used methods focused on Euclidean distance and considered only spatial similarity. Euclidean distance is not a...

OMCAT: optimal maintenance of continuous queries' answers for trajectories
We present our prototype system, OMCAT, which optimizes the reevaluation of a set of pending continuous spatio-temporal queries on trajectory data, when some of the trajectories a...

Lazy Updates: An Efficient Technique to Continuously Monitoring Reverse kNN
In this paper, we study the problem of continuous monitoring of reverse k nearest neighbor queries. Existing continuous reverse nearest neighbor monitoring techniques are sensitive...

A Generic Framework for Continuous Motion Pattern Query Evaluation
We introduce a novel query type defined over streaming moving object data, namely, the Continuous Motion Pattern (CMP) Queries. A motion pattern is defined as a sequence of distin...
