Access Delay Analysis of IEEE 802.11 DCF

Modeling, Performance Analysis, and Optimization of Single Hop IEEE 802.11 Networks with Large Propagation Delays: Challenges and Solutions Abstract—We consider single-hop topologies with satu-rated transmitting nodes, using IEEE 802.11 DCF for medium access, where the propagation delays among the nodes are not negligible compared to the backo slot duration. In this situation, we ﬁnd that ... Propagation delay influence in IEEE 802.11 outdoor ... System throughput decreases as the Figs. 6(a) and 7(a), transmission delay increases as the propagation delay rises; this decrease is accentuated as the propagation delay rises, particularly when the propagation propagation delay increases in multiples of the slot time for delay grows in multiples of the slot time. any data frame payload size (cf. Figs. 6(a), 7(a)). In this Finally, Table 3 ...
