Collecting system, collecting apparatus, and power control method

A collecting apparatus comprising a processor configured to:

• determine whether communication quality received from a node using multi-hop communication for communicating with a plurality of nodes is higher than a certain threshold;
• and
• output a change command to the node associated with the communication quality when determining that the communication quality is higher than the certain threshold, the change command being a command to change an amount of transmission power in the multi-hop communication.

A power control method that is implemented by an information processing apparatus, the power control method comprising:

• determining, by a processor of the information processing apparatus, whether communication quality received from a node using multi-hop communication for communicating with a plurality of nodes is higher than a certain threshold;
• and
• outputting, by the processor, a change command to the node associated with the communication quality when determining that the communication quality is higher than the certain threshold, the change command being a command to change an amount of transmission power in the multi-hop communication.
