The results of analysis and computer simulations show that the theoretical throughput is in good agreement with the throughput obtained from computer simulations under the propagation delay less than 20 ìs.
When the propagation delay is more than 20 ìs, the throughput obtained from the simulation results becomes larger than the theoretical throughput because of short-term unfairness.
The throughput degradation for a transmission rate of 6 Mb/s and a propagation delay of 40 ìs is 16.8 %; this propagation delay corresponds to a transmission distance of 12 km.
