Claim 8:
9. A control method of controlling transmission timings of a plurality of communication devices existing under a network device and each transmitting a data signal toward the network device at a transmission period being associated with each of the communication devices, the control method comprising:
determining a plurality of collision-occurrence-estimated devices for which transmission collision is estimated to occur due to overlapping of transmission schedule timings among the plurality of communication devices;
executing transmission control of transmitting, to each of some of the plurality of collision-occurrence-estimated devices, each of a plurality of timing distribution control signals for distributing transmission timings of the plurality of collision-occurrence-estimated devices; and
executing transmission control of allocating, from a plurality of data rates whose diffusion rates differ from one another, a use data rate to each of some or all of the plurality of timing distribution control signals, in such a way that use data rates being associated with the plurality of timing distribution control signals are distributed, and transmitting each timing distribution control signal by use of a use data rate allocated to each timing distribution control signal.
