After sensor nodes are deployed, when an edge node accommodating individual sensor nodes has entered a high-load state, the lead is distributed to a low-load edge node receiving the same semantic information. A sensor network system comprises a sensor node for generating semantic information by applying sensed numerical data to a defined information format, a broker node for transferring the semantic information generated by the sensor node, and the server node for registering a fitter condition for semantic information to be acquired, and, when the broker node accommodating the sensor node has entered a high-load state, searches for another broker node which is in a low-load state and is capable of transferring the semantic information which has been transferred by the high-load broker node, and switches the accommodating relationship of the sensor node from the high-load broker node to the low-load broker node. |
