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

摘要

A computer apparatus makes an information acquisition request to any of multiple node devices. Each node device (20) has a sensor data search section (51) for searching a sensor data storage sections of the multiple node devices for a sensor data according to the information acquisition request and acquiring the sensor data and an information transmission section for transmitting the sensor data acquired by the sensor data search section (51) or calculation result data acquired on the basis of the sensor data to the computer apparatus.
