This study studies the received buffer blocking problem caused by traditional concurrent multipath transfer protocol. The authors propose a new transport protocol, named wireless concurrent multipath transfer stream control transport protocol (WCMT-SCTP), to solve the received buffer blocking problem. It can bind certain data streams to certain paths and use multiple active paths to transfer data simultaneously. The authors evaluate the performance of WCMT-SCTP through theoretical analysis and extensive simulation. Both simulation and analysis results show WCMT-SCTP can improve the system throughput obviously and keep the independence of data streams.
