Development of a realistic simulation model for IEEE 802.11n based on Experimental Results

in this paper, a peer-to-peer experiment in an open field environment was conducted for both constant and exponentially distributed sets of traffic, in order to build a realistic simulation model. The constant and exponential traffic were used because the emulate control and voice traffic respectively. The constant distributed traffic was sent at a constant inter-arrival rate whilst the exponentially distributed traffic was sent at an exponential inter-arrival rate to the destination. Both sets of traffic were sent over Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) at various distances apart under non-congested network condition. A corresponding simulation model was developed, and a shadowing model was applied in order to replicate the performance of the real life experiment. The value of the path loss exponent and shadowing deviation were varied to the point where the performance of the simulation model was almost identical to the real life experiment. The traffic received between the simulation and experiment has a margin of error in the region of ±1%; however the delay of the experiment was much higher than the simulation due to time synchronization.
