The growing popularity of multihoming techniques has motivated the rise of multipath protocols. Multipath TCP (MPTCP), as an extension of TCP, can use multiple paths to deliver data in parallel without influencing any functionality of TCP. Although applying MPTCP to mobile terminals for data transmission can provide many and attractive benefits, including performance improvement and latency reduction, there is still significant ongoing effort addressing many remaining concerns. One major concern is related to handling buffer blocking. Many researchers have attempted to optimize data scheduling way to mitigate this problem. In this paper, we propose a multiple attribute-aware data scheduling strategy for MPTCP (MPTCP-MA 2 ). The proposed MPTCP-MA 2 solution is invoked to undergo three phases: (i) monitor each path's status information constantly, (ii) use an optimized path sorting algorithm to compare and sort all available paths, (iii) adaptively transmit data packets over multiple paths according to the path sorting result. Furthermore, MPTCP-MA 2 focuses on mitigating buffer blocking as well as boosting the robustness of the data transfer. The simulation result shed light on how MPTCP-MA 2 achieves a little higher throughput than existing solutions.
