<P>PROBLEM TO BE SOLVED: To suppress a network traffic. <P>SOLUTION: A server node 110 acquires the topology of a sensor network. When the topology is changed, the server node 110 acquires, from a node included in the sensor network, classifications of events to be output by the pertinent node and attribute names and attribute values of aggregation attributes for aggregating a plurality of nodes including the pertinent node. The server node 110 is a node which outputs partial events among the classifications of a plurality of events input by a module, and extracts nodes having the same attribute values belonging to the aggregation attributes whose attribute names are the same as those of the aggregation attributes defined in the module between those nodes. The aggregation processing of the events turned into a trigger to start service providing processing is integrated into the module. When a plurality of nodes are extracted, the server node 110 arranges the module at an upper node in which each node is housed by referring to the topology of the sensor network. <P>COPYRIGHT: (C)2013,JPO&INPIT |
