TCP throughput performance in IEEE 802.11-based multi-hop wireless networks

This paper studies TCP throughput performance in IEEE 802.11-based multi-hop wireless networks where nodes can have different physical transmission modes, e.g., modulation schemes and packet transmission rates. The physical transmission modes affect the link layer transmission performance, which further affects the TCP throughput performance. Selecting the TCP congestion window size is important for improving TCP throughput. We use simulation to demonstrate the effect of different physical layer modes on the TCP throughput performance and find the optimal TCP window size upper bound.
