Abstract :
An analytical model for studying the performance of the delayed acknowledgment (Dly-ACK) mechanism in the IEEE 802.15.3 standard over wireless Rayleigh-fading channel is developed. A three-state Markov chain is applied to approximate the correlated transmission errors. Explicit mathematical expressions for the goodput and efficiency of Dly-ACK are derived. It is found that the correlation between consecutive transmission errors has a significant impact on the goodput and efficiency of the Dly-ACK mechanism. The goodput tends to increase as the size of the Dly-ACK burst increases; however, the amount of increase depends on the underlying delay. Simulation results are given to validate the analytical results.
