Abstract
A communication system includes communication devices configured to be connected to one another through a network. A root device which is one of the communication devices stores system information including address information and information on availability of communication of the communication devices. The root device is configured to transmit the system information periodically. Each of the communication devices is configured to send an acknowledgement message to the root device when receiving the system information. When an acknowledgement message from one of the communication devices has not been received by the root device, the root device is configured to rewrite the information on availability of communication of the communication device from which the acknowledgement message has not been received by the root device, as incommunicable, and to update the system information accordingly.
