Figure 4

Behavior of the aggregate throughput as a function of , for five different values of the packet size as noticed in the legend. In each simulated scenario there are contending stations transmitting at 1 Mbps. Other parameters are as follows: , , and . The values of are noticed on the abscissa, whereas the horizontal lines, labeled by , represent the maximum aggregate throughput (link capacity) evaluated through (13) in each considered scenario. All the thick curves refer to bytes, and various packet error probabilities as noticed in the figure.
