Abstract
Each node in a communication system operates on a repetitive internal timing cycle, at certain phases in which the node transmits data and state variable signals. The state variable signals indicate the node's data transmission timing. Each node has a virtual node calculator that simulates the timing cycles of neighboring nodes according to the state variable signals received from those nodes, and a phase calculator that varies the phase state of the node according to the simulated phase states of the neighboring nodes. Neighboring nodes can therefore interact continuously, even though they transmit state variable signals only intermittently. Consequently, a group of neighboring nodes can autonomously establish and maintain transmission time slots of equal length.
