Abstract: The present invention relates to a method of dynamic channel switching in a wireless mesh network that is in conformance with an IEEE 802.11s standard. The method comprises the steps of transmitting a request frame to a node for scanning a channel associated with the node; determining a link quality of the channel; receiving a response frame from the node; and switching to the channel if the switching metric is larger than a switching threshold, wherein if otherwise, remain unswitched. The switching metric integrates the interference, transmission frame size, latency of channel switching and data rate of the node on the channel.
