Abstract

With the development of pervasive systems and positioning technology, the analysis of data resulting from moving objects trajectories has attracted a particular interest. Those data are called trajectory data and are stored in a suitable repository called trajectory data warehouse (TDW). TDW view definitions are constructed from heterogeneous mobile information sources schema. Those latter are more and more autonomous and they often evolve by changing their contents and/or their schema then the TDW view definition may become undefined and consequently the analysis process may be affected. For this reason, it is important to achieve view definitions restoring or synchronization following schema changes occurred at the heterogeneous mobile information sources. The goal of this paper is to propose a TDW view definition maintenance based on mobile agent view adaptation system.
