1. A channel allocation method, comprising:
determining a communication device type from a plurality of communication device types based on information received from neighboring communication devices; allocating a channel according to the communication device type; and transmitting the communication device type and information about the allocated channel to the neighboring communication devices, wherein:
the plurality of communication device types comprises a fixed communication device fixed on a single channel and a switching communication device capable of switching channels, among a plurality of channels;the determining of the communication device type comprises:
transmitting QUERY messages to the neighboring communication devices when connecting to a wireless mesh network;receiving response messages from the neighboring communication devices in response to the transmitted QUERY messages; anddetermining the communication device type based on the received response messages; andthe determining of the communication device type based on the received response messages comprises determining the communication device type as a fixed communication device when a fixed communication device does not exist among the neighboring communication devices.
