Executive Summary

In this paper, the authors provide cross-layer analysis of the impact of mobility and medium access control parameters in IEEE 802.11 wireless network on variety TCP versions. Performances of the Internet transport protocols may significantly degrade when end to end connection includes wireless links where packets delays and losses are caused by mobility and transmission errors. The analysis showed that the impact of medium access control parameters, such as number of retransmissions and interface queue length in 802.11 networks on the obtained throughput, is stronger for terminals with higher mobility.
