Mobile ad hoc network modulation coding adaptive selection method based on separation of control plane and data plane

According to the modulation coding adaptive selection method for the mobile ad hoc network based on separation of the control plane and the data plane, in the mobile ad hoc network with the separation of the control plane and the data plane, a carrier monitoring multi-channel access CSMA mechanism is adopted in a control time slot, and situation information fused by the mobile ad hoc network is competed and sent, so that survey and perception of neighbor nodes are completed; the situation information comprises link transmission quality and node queue length; in a data plane, a CSMA mechanism is also adopted, but situation information of a control plane needs to be utilized to form a certain network order, and throughput reduction caused by wrong packets and collision is reduced; on the basis of a traditional rate adaptive algorithm based on a signal-to-noise ratio (SNR), the algorithm is improved, and the algorithm is applied to mobile ad hoc network equipment adopting separation of a control plane and a data
