Abstract
Each node in a communication system transmits and receives state variable signals indicating internal node states or timings, generates transitions in its internal state or timing at a basic rate but at timings adjusted according to the received state variable signals, transmits data in time slots synchronized to the output state variable signals, receives data signals from the other nodes, detects collisions between the received data signals, and changes the timing of its time slots when a collision is detected, by shifting the phase of the transitions, or by inserting additional dummy transitions and transmitting corresponding dummy output state variable signals. The nodes can thereby assign their own time slots and avoid collisions autonomously.
