Provided is a sensor network system including a plurality of sensor nodes and a server that collects data from the plurality of sensor nodes. In the sensor network system, when a first sensor node, which is one of the plurality of sensor nodes, acquires data, the first sensor node selects, on the basis of a first energy for directly transmitting the data to the server, a second energy for transmitting the data to another sensor node and a third energy for holding the data in the first sensor node, either a first transmission mode to directly transmit the data to the server or a second transmission mode to transmit the data to the other sensor node. The first sensor node then transmits the data to the server or the other sensor node in the selected transmission mode. |
