    Abstract: A GR-tree method and a query aggregation (Query Aggregation) method have been proposed for spatial
query processing with space query processing techniques for existing wireless sensor networks. However, such
a spatial query processing technique considered the optimization of spatial queries but it was not taken into
consideration about the question and answer of time and due to the increase of the index reorganization cost and
the communication cost of the parent sensor node. There is a problem that the energy consumption that requires
the most efficiency increases at the wireless sensor node. In this study, we solve the problem of such a spatial query
processing technique and investigate the IR-tree (Itinerary based R-tree) for the more efficient time space (Spatiotemporal)
Present.
