<p>[PROBLEMS] In a communication network including many nodes connected to each other, there frequently occurs a communication collision, which interferes with the exertion of the capability of the communication path, resulting in occurrences of communication delay. There is provided a communication system wherein a high-rate communication can be performed without any collisions. [MEANS FOR SOLVING PROBLEMS] A rhythm node is provided on a communication network. For an upstream communication, a transmission reminder message is transmitted by broadcast from the rhythm node, and each of dominant nodes, after receiving the transmission reminder message, performs an upstream communication when a predetermined standby time has passed. For a downstream communication, the rhythm node assigns a downstream communication right to a tonic node.</p> |
