摘要：Simultaneous Multipath Transmission has inherited problem of outoforder packet reception. This causes receiver buffer (Rbuf) blocking, which degrades the aggregated throughput and restricts the efficiency of fastest path to its slowest companion path. This research proposed SMTAdaptive Fast Retransmit mechanism that uses fast retransmission threshold, adapts to the size of Rbuf in order to encounter Rbuf blocking problem. In bandwidth and packet loss based disparity scenarios, SMTAFR achieved the highest aggregated throughput and remained unaffected with respect to various Rbuf sizes. In delay based disparity scenarios, the performance of SMTAFR affected with a decrease in Rbuf size. Simulation results revealed that SMTAFR has solved the Rbuf blocking problem in bandwidth and packet loss disparity scenarios. There is a need for the multipath disparity aware scheduler to improve SMTAFR performance in delay based disparity.
