Abstract
Communicating nodes in a network exchange state variable signals indicating the timing of periodic operations performed at the nodes. Each node autonomously controls the timing of its periodic operation so as to distance the timing from the timing of the periodic operations performed at other nodes. If the periodic operations include data transmission, this arrangement enables the nodes to avoid data collisions. The nodes can also adapt autonomously to changing conditions such as changing priority levels and the addition and removal of nodes.
