In terms of improving TCP performance in Mobile Ad Hoc-NETwork (MANET), it is well known that small congestion window size of TCP connection improves TCP performance. We propose a new TCP algorithm to improve TCP performance in MANET. The basic idea of our approach is that TCP receiver estimates the optimum window size and then sets congestion window limit to an optimal value by the advertised window. It is found that our algorithm, using ns-2 simulator, improves TCP performance up to 60% in various topologies in MANET.
