Improving the performance of Transmission Control Protocol (TCP) associated with the presence of multi-hop is one of the research challenges in wireless mesh networks. Wireless mesh networks have large round trip time variations and these variations are dependent on the number of hops. The end-to-end TCP throughput degrades rapidly with increase in number of hops. This is one of the biggest problems of TCP over wireless mesh networks. In wireless mesh network, when congestion loss and wireless loss are co-existed the number of packets dropped increases and will have adverse effects on TCP and its congestion control mechanism which leads to low throughput. In this paper, we designed a TCP scheme called TCP SAC for multi-hop wireless mesh networks, by modifying the sender side congestion control functionality of TCP NewReno, which is tuned towards improving the performance of TCP. The simulation results show that TCP SAC has more than 10% higher performance than TCP NewReno, Reno, Sack and Vegas in multi-hop wireless mesh networks.
