Embodiment Construction
[0041]Embodiments of the present invention are described below through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation modes, and various modifications or changes can be made to the details in this specification based on different viewpoints and applications without departing from the spirit of the present invention.
[0042] The method of the invention is suitable for single radio frequency OFDMA wireless mesh network. The traditional channel bandwidth adjustment method is to select one from different channel bandwidth options (such as 5, 10, 20, 40MHz), and the center frequency of the channel can be adjusted. The traditional method to adjust the channel bandwidth has the disadvantages that the adjustment step of the channel bandwidth is very large ...

The invention provides a method for dynamically regulating the channel bandwidth of a wireless mesh network. The method comprises the steps as follows: S1, first receiving lists, first output lists, second receiving lists and second output lists are established for nodes; S2, a sending node sends a real time analyzer (RTA) message to a receiving node when an access time delay interval is reached; S3, the receiving node returns a cordless terminal adaptor (CTA) message to the sending node; S4, the sending node broadcasts an artificial neural network (ANN) message comprising a distribution list; S5, nodes receiving the ANN message updates own first receiving lists, first output lists and second receiving lists; S6, the nodes receiving the ANN message sent by the receiving node updates own first receiving lists, first output lists and second receiving lists; and S7, each node receiving the ANN message sent by the receiving node updates own first receiving list, first output list and second receiving list. By using the method, the channel bandwidth can be dynamically regulated.
Description
technical field [0001] The invention relates to the technical field of network channel bandwidth adjustment control methods, in particular to a method for dynamically adjusting channel bandwidth of a wireless mesh network. Background technique [0002] The wireless mesh network is composed of mesh routers (routers) and mesh clients (clients). The mesh routers constitute the backbone network and are connected to the wired internet network, responsible for providing multi-hop wireless internet connections for the mesh clients. Wireless Mesh network (wireless mesh network), also known as "multi-hop" network, is a new wireless network technology that is completely different from traditional wireless networks. In a wireless mesh network, the communication between the source node and the destination node is realized through multi-hop forwarding. Since different nodes in the network have different data flow requirements, some transmission links need to support higher data flow, wh...
