PROBLEM TO BE SOLVED: To provide a communication system that can automatically construct a network, as well as reducing power consumption of each node in the network.SOLUTION: A slave node S0 calculates timing of next receiving annunciation information based on timing information included in annunciation information. The slave node then accepts input of annunciation information transmitted from a management node M and transmits a registration request. The slave node further accepts input of annunciation information transmitted from the management node M and determines whether the slave node itself is registered in the network based on slot assignment information included in the annunciation information. When the slave node determines that the slave node itself is registered in the network, the slave node calculates timing for receiving a reply request transmitted from the management node M. |
