  • INFORMATION PROCESSING SYSTEM, INFORMATION PROCESSING METHOD, AND PROGRAM
    Publication number: 20180052988
    Abstract: An information processing system includes a data acquisition unit that acquires time-series data related to power consumption of a device, a specification unit that specifies the device corresponding to the power consumption on the basis of the acquired time-series data, and an authentication information acquisition unit that acquires authentication information of the device specified by the specification unit.

  • Sensor network system, sensor network control method, sensor node, sensor node control method, and sensor node control program
    Patent number: 9712394
    Abstract: A sensor network system 1000 is provided with a plurality of sensor nodes 1100, . . . and configured to decide a parent node for each of the plurality of sensor nodes so as to form a network topology having a tree structure using each of the plurality of sensor nodes as a node. The sensor network system forms the network topology so that, with respect to each of the plurality of sensor nodes, the number of child nodes owned by the sensor node is close to a value obtained by multiplying a maximum containing number, which is a maximum number of sensor data that can be contained by one packet, by a natural number (1200).
