Hybrid networks where packets travel through both a geostationary satellite and a terrestrial local wireless link are a particularly challenging environment with respect to TCP performance. The reason is that such networks exhibit both a high latency and a high packet loss, a combination that stresses TCP's congestion avoidance algorithm. Accurate modelling of the packet loss process in such networks is not an easy task, so very simplified models are frequently used. The paper starts from channel state measurements done on a fixed-speed IEEE 802.11 terrestrial channels and it use the ns-2 simulator to evaluate the performance of TCP on it.
