NETWORK SYSTEM NODE DEVICE GROUP COMPUTER DEVICE AND METHOD FOR TRANSMITTING AND RECEIVING SENSOR DATA

摘要

A computer device sends an information acquisition request to any node device from among a plurality of node devices. Each node device (20) has: a sensor data search unit (51) that searches the sensor data storage units of the plurality of node devices in response to the information acquisition request and acquires sensor data; and an information transmission unit that transmits to the computer device the sensor data acquired by the sensor data search unit (51) or computation result data obtained on the basis of this sensor data.
