    • A method for creating a grid-based tree in a multiple sensor network includes: dividing an entire area in which a base station node and a plurality of sensor nodes are disposed into grid areas; assigning a grid ID to each of the grid areas; setting, sequentially from the base station node to each of the sensor node, level information, candidate child nodes and candidate parent nodes; storing a grid ID of a grid area in which the respective nodes locate; selecting, for the respective sensor nodes, a parent node based on the grid ID, the level information, and the candidate parent nodes; and calculating, for the respective nodes, minimum bounding rectangles each of which includes a child node of corresponding node and nodes descended from the child node. The grid-based tree is calculated by using the minimum bounding rectangles.

    • The present invention relates to a sensor network managing apparatus and a method thereof. The sensor network managing apparatus according to the present invention receives a query that includes a spatial join predicate for searching for target sensor nodes and a comparison predicate that is different for each sensor network, and generates query execution order information for searching for the target sensor nodes based on the spatial join predicate and the comparison predicate, wherein the spatial join predicate is related to a spatial location between sensor nodes respectively included in different sensor networks, and the comparison predicate are related to sensing values of sensor nodes of the sensor networks. In addition, the sensor node managing apparatus executes queries for the spatial join predicate and the comparison predicate on the plurality of sensor nodes on the basis of determined query execution order, and then extracts target sensor nodes as the query results. According to the present invention, an efficient method for searching for user-desired sensor nodes in more than two different sensor networks can be provided.
