Abstract

An analytical model for studying the performance of the Delayed Acknowledgement (Dly-ACK) mechanism in IEEE 802.15.3 over a fading channel is developed. A three-state Markov channel model is used to approximate both correlated and uncorrelated error processes. Explicit mathematical expressions for the goodput and efficiency of Dly-ACK are derived. It is found that the Dly-ACK mechanism yields higher goodput in a burst error environment than in a random error environment. The goodput tends to increase as the size of the burst increases; however, the amount of increase depends on the underlying delay. Simulations results are given to validate the analytical results.
