In this paper, we developed an analytical frame work for 802.11 One-ACK protocol under saturated condition with imperfect wireless channel. We developed a probabilistic model to handle the retransmissions of fragmentations which are corrupted due to bad channel condition. A modified Markov chain model is introduced to better model the backoff counter operation. The analytical results are verified against NS-2 simulation with great precision.
