| Abstract: | Adaptive block acknowledgement (B-ACK) is used to reduce the long delay caused by frequent handshake,
and adaptive coding and modulation (ACM) is used to overcome throughput decline. This method can avoid the long
time delay caused by frequent retransmission of data packets, overcome the throughput decline, and improve the
efficiency of nodes accessing the aviation wireless cooperative network. According to the change of the packet error
rate, the strategy of node access to the network is adaptively adjusted to solve the problems of low throughput and large
delay in the current aviation wireless cooperative network. |

| Keywords: | block acknowledgement adaptive coding and modulation time division multiple access delay throughput
