Abstract
A first apparatus receives, from a second apparatus, a signal including information on first time-periods each associated with an occupancy rate, using a wireless channel. The first time-periods each indicate a time-period during which data are scheduled to be collected by the second apparatus, and the occupancy rate indicates a ratio of a duration-time during which data are actually collected by the second apparatus using the wireless channel, to the each first time-period. The first apparatus, based on the occupancy rate and the received power of the first signal, calculates interference values each indicating a degree of interference caused by a radio wave from the second apparatus during the each first time-period, and acquires, based on the calculated interference values, second time-periods during which data are scheduled to be collected by the first apparatus, and collects data from a node apparatus during the third time-periods using the wireless channel.
