Its not the congestion window problem. In NS2, it is the receiver window which is set to be default 20. You should change the receiver advertized window.
An example command "$tcp_conn set window_ 100". It will make the receiver advertized windpw to be 100 for the tcp connection denoted by $tcp_conn.
