In the embodiment of the present invention, the form of data sending request message has a variety of, optionally, can be RTS message, similarly, data, which send the form replied message, can also a variety of, can be CTS message optionally.
In the embodiment of the present invention, received in receiving end/sending end after data transmission is replied message after the packet of specified WiFi channels, in addition to following operation：
If being correctly decoded packet, on the channel for receiving the packet, sent to transmitting terminal and correct
The corresponding ACK of packet of decoding.
In this scenario, transmitting terminal is detected after the WiFi channels of free time, by sending data sending request message informing receiving terminal on idle WiFi channels, these idle WiFi channels transmitting terminals can be used, and receiving terminal further determines WiFi return paths from the idle WiFi channels that transmitting terminal is detected, then, at least two discrete WiFi channel packets of the transmitting terminal in the WiFi return paths that receiving terminal is determined, even if the WiFi channels specified are discontinuous, it can also be transmitted, therefore, improve the utilization rate and efficiency of transmission of resource.

Certainly, in actual applications, there may be the node more than three, now, when the adjacent node of any two is communicated, transmitting terminal can perform step 200- steps 220, as when being communicated between node n-1 and node n, node n-1 can perform step 200- steps 220, node n can perform step 300- steps 320, when being communicated between node n and node n+1, node n can also perform step 200- steps 220, and node n+1 can perform step 300- steps 320.
When return path there are many hop nodes, if node n there are Slow deposit data bags, in order to reduce time delay, efficiency of transmission is improved, node n can also send packet while CTS message is sent to node n-1 to node n+1；If node n is either with or without Slow deposit data bags, node n receives the packet of node n-1 transmissions after CTS message is sent to node n-1, just can send packet to node n+1.
Certainly, if the node n packets that both receiving node n-1 is sent, meanwhile, packet also is being sent to node n+1, in order to avoid interference, the accuracy of the packet received is being improved, node n is received
The frequency range for the packet that the node n-1 arrived is sent, is differed with node n to the node n+1 frequency ranges for sending packet.
