ABSTRACT:
Communication control apparatus provided in nodes forming a telecommunications network includes a transmission timing calculator responsive to the state of the phase of the own node to determine a timing at which the node transmits data. The calculator is responsive to a state variable signal transmitted by a neighboring node and reflecting the phase of the neighboring node to change the state of the phase of the own node in accordance with a time development rule. The calculator monitors a phase difference of the own node against the neighboring node to calculate, based on the difference, the ratio of collision on data transmission timing between the own and neighboring nodes. The stress value corresponding to the collision ratio is stored time-serially. A stress response function value is generated such that the stored stress value causes the time development rule to shift the phase with its value made at random.
