One major concern of concurrent multipath transfer (CMT) in multi-homed Stream Control Transport Protocol (SCTP)-based heterogeneous wireless networks is that the utilization of different paths with diverse QoS-related networking parameters may cause packet reordering and buffer blocking. Although many efforts have been devoted to addressing the packet reordering issue, their sender-dependent-only scheduler does not consider balancing overhead and sharing load between the SCTP sender and receiver. This paper proposes a novel Receiver-driven Multipath Data Scheduling strategy for CMT (CMT-RMDS) necessitating the following aims: (1) alleviating the packet reordering problem, (2) improving the CMT performance, and (3) balancing overhead and sharing load between the sender and receiver. Simulation results show that the proposed CMT-RMDS solution outperforms the existing CMT solutions in terms of data delivery performance in heterogeneous wireless networks.
