Figure 2: Throughput for the 2-way mechanism as a function of the packet rate , for , , packet size bytes, and different values of and as noticed in the respective legends. Continuous straight lines refer to the linear model of the throughput derived in (9), while the horizontal line corresponds to noticed in (13). Dashed lines, labeled Thr, refer to the theoretical throughput in (7), while dash-dotted lines labeled NS2 identify the simulation results obtained with ns-2.
