PROBLEM TO BE SOLVED: To provide a technique in which an actual sensor and a virtual sensor can be used easily in a sensor network.SOLUTION: A processing control section determines whether a sensor to be an acquisition source of sensing data which has received a request is an actual sensor or a virtual sensor. When determining it as the actual sensor, the processing control section acquires sensing data of the relevant actual sensor from sensing data DB, and when determining it as the virtual sensor, the processing control section reads management data of the relevant virtual sensor from management data DB of the virtual sensor. On the basis of the read management data, the processing control section acquires necessary sensing data from the sensing data DB to be processed, thereby acquiring the sensing data of the relevant virtual sensor. |
