Mobility patterns

  title={Mobility patterns},
  author={C{\'e}dric du Mouza and Philippe Rigaux},
We present a data model for tracking mobile objects and reporting the result of continuous queries. The model relies on a discrete view of the spatio-temporal space, where the 2D space and the time axis are respectively partitioned in a finite set of user-defined areas and in constantsize intervals. We define a query language to retrieve objects that match mobility patterns describing a sequence of moves and discuss evaluation techniques to maintain incrementally the result of queries.
