—Multi-hop wireless networks have evolved as a key and promising wireless technology for a large variety of applications ranging from home networking to transportation systems, defense and medical systems. Transmission Control Protocol (TCP) is a widely deployed transport protocol and its congestion control mechanisms guarantee reliable delivery of data and efficient allocation of network resources. Congestion control mechanisms implemented in TCP have evolved significantly to better the performance of TCP on different types of communication networks. Recently, a lot of research has focused on improving the performance of TCP connections with large congestion windows, resulting in new variants called “high-speed” TCP variants. In this paper, we study the performance of high-speed TCP variants in multi-hop wireless networks in terms of network throughput. Another metric, expected throughput is used for comparison of throughput when nodes are mobile.
