Aiming at the same frequency interference, in the channel increased frequency recognition function before the consultation and put forward based on the frequency of perception multiple channel CC-MMAC agreement, simulation verification protocol can effectively reduce the co-channel interference. Channel quality changes with time by the effects of the decline and dispersion, thus cause a certain impact to the network performance, therefore the Gauss channel and the fading channel MAC protocol model are established; in study of rate based on adaptive control, performance analysis take to the rate adaptation leave C protocol, put forward based on the chance rate adaptive OAR DCA channel protocol can improve the network throughput effectively.
