通信システム、制御ノード装置及びその制御方法、被制御ノード装置及びその制御方法、プログラム
Document Type and Number:
Japanese Patent JP5676911
Kind Code:
B2
Abstract:
A communication network includes a control node and one or more controlled nodes. The control node transmits allocation information, which indicates a non-conflict region of each node in the communication frame, in a non-conflict region allocated to the control node, if an access request has been received from a new node, allocates a non-conflict region of the new node to the communication frame, and updates the allocation information based upon the allocation. The controlled node relays the allocation information in the non-conflict region of the controlled node if the allocation information has been received, and relays the access request in the non-conflict region of the controlled node if the access request has been received. The new node detects the conflict region and non-conflict region of the communication frame based upon the received allocation information, and transmits, in the detected conflict region, the access request to access the communication network.
