- Abstract
The impact of capture effect on the saturation performance of distributed coordination function (DCF) is studied. On the basis of the inference of capture probability and the validation of the channel states and the node states synchronously transiting, an improved slotted analytical model is proposed. Making use of the proposed model, the saturation performance of IEEE 802.11 DCF under capture effect is analyzed, and the close-form expressions of its normalized saturation throughput and average access delay are presented. Furthermore, the relation between saturation state and average access delay is illustrated. Theoretical analysis and simulation results show that the slotted analytical model can efficiently improve the precision in theoretical estimate of saturation performance of IEEE 802.11 DCF mechanism.
