1. A method for channel switching in a wireless mesh network, comprising:
a slave node in the wireless mesh network receiving a channel switching command broadcast by a master node to perform channel switching;
the slave node determining whether the channel switching is successful, if the channel switching is successful, the slave node searching for the master node or a mesh network containing the master node for networking, if the channel switching is not successful, the slave node exiting a current invalid mesh network, scanning a mesh network after the channel switching, and joining in the scanned mesh network,
wherein after the slave node is successfully switched, the method further comprises: marking the networking as a valid mesh network, adding node information of the valid mesh network into a beacon frame, and broadcasting the beacon frame carrying the node information of the valid mesh network.
