ABSTRACT:
A communication timing control apparatus for use in the nodes of a communication system includes a signal communication unit that transmits a state variable signal to neighboring nodes and receives state variable signals from those nodes. An external control signal, such as a beacon signal transmitted by a control node, is also received. The state variable signals indicate internal operating states or timings of the nodes; the control signal indicates a basic transition rate. A timing decision unit causes internal state or timing transitions to occur at timings responsive to the basic transition rate and the received state variable signals, adjusting the transition timings so as to avoid signal collisions and to adapt to changing system conditions, Use of the control signal enables a steady timing state to be reached quickly.
