[0031] The wireless network congestion control method with attached cross-layer design of the present invention is realized through the following steps:
[0032]1. In order to enable the confirmation frame to carry congestion status information, we define an idle control bit in the confirmation frame as the congestion status flag bit. If the congestion status flag bit is set to 0, the confirmation frame is an ACK that does not carry congestion information. frame; if the congestion flag bit is set to 1, the acknowledgment frame is an ACKC frame carrying congestion information. When the receiver of the data frame replies with an ACKC frame to the sender of the data frame, it means that the receiver is in a congested state; when the receiver of the data frame replies with an ACK frame to the sender of the data frame, it means that the receiver is in a non-congested state.
[0033] 2. In order to judge its own congestion status, divide the buffer of each node in the network into r...
