摘要：

The invention provides a communications system with few transmission collisions. The communications system is provided with a rhythm node, which rhythm nodes transmit synchronized upstream transmission instigation messages, upon receipt of which dominant nodes perform upstream transmissions sequentially and after their predetermined standby times. The rhythm node transmits synchronized downstream transmission instigation messages, upon receipt of which tonic nodes perform downstream transmissions sequentially and after their predetermined standby times. Transmissions of upstream transmission instigation messages and downstream transmission instigation messages are synchronized. Transmissions are efficient and without collisions because individual nodes perform transmissions in sequence rather than instantaneously.
