Simulation research of 802.11n channel model D in NS2

In order to imitate the channel characteristics of 802.11n WLAN, this paper analyzes channel model mechanism of Markov stochastic process and implements the extensional module of 802.11n channel in NS2. In the end, through comparing simulation results with standard TGn model, we verify the accuracy of this module which provides efficient physical layer channel simulation foundation for the research of 802.11n protocol.
