Abstract:
An actor node according to the present invention includes a dynamic change unit for temporarily changing a coverage block in which data are obtained from a sensor node and temporarily causing another actor node to obtain, on behalf of the actor node, data from the sensor node arranged in a partial region of at least a portion of the coverage blocks. The dynamic change unit obtains identification information unique to the another actor node from the another actor node. The dynamic change unit notifies, to the sensor node arranged in the partial region, the obtained identification information. The dynamic change unit notifies, to the another actor node, a portion of the hash chain and a temporary key generated using the obtained identification information and the key used for communication with the sensor node arranged in the partial region.
