摘要：
The invention provides a method of managing a network in which the configuration of communication devices can be freely modified and each terminal can operate as a hub terminal for controlling the network, and a communication device. Following network management information transmitted by the hub terminal periodically, each leaf terminal transmits terminal synchronization information and then transmits data. The network management information includes network ID retained by the hub terminal, station ID information in the form of information indicating the use/non-use of station ID in the network, and a terminal synchronization information transmission request which designates the leaf terminal which should transmit a terminal synchronizing signal. The leaf terminals designated by the terminal synchronization information transmission request transmit the individual terminal synchronization information sequentially following the network management information.
