In ITS-DSRC system employed with road-to-vehicle spot communicative form the packets are lost continuously by the fading on wireless link and at uncommunication zones. When many packets are lost continuously, the FRT of typical TCP does not function all lost packets, client cannot but wait for timeout at the server, the throughput falls sharply. So this paper proposes the argorism (Continuous-FRT) that FRT is performed to all lost packets by changing only a client side, and a computer simulate the improvement effect of a throughput. Moreover, by the case where the communication rupture more than window size occurs, although Continuous-FRT cannot function, this is solved by using Freeze-TCP strong against prolonged communication rupture.
