Abstract:
1. A node used as a first node in a communication system that also includes at least a second node, the first node comprising: a signal communication unit operable to transmit a first state variable signal to the second node and receive a second state variable signal from the second node, the first state variable signal indicating a first operating timing of the first node, the second state variable signal indicating a second operating timing of the second node; and a timing decision unit operable to generate the first operating timing periodically at a basic rate subject to temporary variations, to generate the first state variable, and to adjust the first operating timing so that the first operating timing and the second operating timing are distanced from each other by varying the basic rate according to a rule that makes the first operating timing and the second operating timing mutually repulsive.
