Distributed Coordination Function Protocol with Unequal Frame Error Rates

This letter provides an analysis of the saturation throughputs of the individual stations (STAs) in a distributed coordination function (DCF) network. Compared with the previous DCF models, our new proposed model is suitable for more general environments where the frame error rates (FERs) are different depending on the transmitting STAs and the numbers of retransmission attempts. Numerical analyses show that FERs significantly affect the STAs' throughputs.
