%X This paper provided an improved Markov model and used Z transform to analyze and compute the MAC delay of 802.11 DCF,which included the non-saturation and saturation delay performance of transmission channel.The numerical analysis of MAC delay in MATLAB matched the network simulation of MAC delay in OPNET 10.0 well,which proved the accuracy of the analysis model in MAC delay predication.The results are beneficial to further designing in theory arguments and data reference.
