Abstract

The problem of high BER (bit error rate) usually plagues the wireless connection, especially for some real time applications such as VoIP (voice over IP) and some military uses. The newly developed transport layer protocol SCTP (stream control transmission protocol) also has to face this problem. Though equipped with many new features, SCTP congestion control mechanism fails to distinguish wireless loss from congestion loss, thus its performance over high BER wireless network suffers from unnecessary congestion window decreasing. To improve the performance of SCTP in such a scenario, a Mac-error-warning method is proposed in this paper. Simulation experiments conducted through extended ns-2 validated that the proposed method could achieve higher throughput. The throughput improvement arrives at 946.22% when BER is 0.0005.
