Abstract
In a communication system including nodes laid out in a grid, each node operates on a repetitive internal timing cycle, at certain phases in which the node transmits data and state variable signals. The state variable signals transmitted by a node indicate its internal phase and its position in the grid. The advance of the phase at each node is governed by a phase response function, which drives neighboring nodes whose data transmissions could collide out of phase with each other, and a synchronization alliance function, which brings certain nodes having positional relationships that preclude data collisions into phase with each other. A highly efficient data transmission timing pattern can thereby be established autonomously.
