“…Since delay is more critical for small size flows, in order to complete the transmission as quickly as possible, Hwang et al [ 77 ] proposed a scheduler which stops the slow path temporarily if there are large delay gaps between different transmission paths. A generic modular scheduler framework was designed in [ 78 ].…”

Multipath TCP (MPTCP) is one of the most important extensions to TCP that enables the use of multiple paths in data transmissions for a TCP connection. In MPTCP, the end hosts transmit data across a number of TCP subflows simultaneously on one connection. MPTCP can sufficiently utilize the bandwidth resources to improve the transmission efficiency while providing TCP fairness to other TCP connections. Meanwhile, it also offers resilience due to multipath data transfers. MPTCP attracts tremendous attention from the academic and industry field due to the explosive data growth in recent times and limited network bandwidth for each single available communication interface. The vehicular Internet-of-Things systems, such as cooperative autonomous driving, require reliable high speed data transmission and robustness. MPTCP could be a promising approach to solve these challenges. In this paper, we first conduct a brief survey of existing MPTCP studies and give a brief overview to multipath routing. Then we discuss the significance technical challenges in applying MPTCP for vehicular networks and point out future research directions.

“…To address the above issues, Hwang and Yoo [31] designed a packet scheduling protocol to give advantage to not only long-lived flows but also short flows. Specifically, it firstly categorized MPTCP paths into fast path and slow path and then freezes the slow path temporarily when the path difference between fast and slow path is large, therefore the small amount of data can be transmitted quickly via the fast path.…”

Multipath TCP (MPTCP) benefits the signals transmission during the progress of array signal processing, since it can provide higher aggregated bandwidth and reliable link connection with the existence of backup paths. However, the small amount files (short flows) appear poor performance with MPTCP, especially when they compete with some larger files (long flows). To alleviate this issue, this paper proposes a MPTCP Transmission Optimization Algorithm for Short Flows, namely MPTCP-TOASF (A MPTCP Transmission Optimization Algorithm for Short Flows). MPTCP-TOASF designs an optimal path group to transmit short flows based on round-trip time (RTT) and switches to traditional MPTCP for transmission of long flows. Moreover, to address the issue that long flows occupy the most of buffer space, MPTCP-TOASF utilizes the idea of the delay-sensitive Veno congestion control over paths in optimal path group, so as to avoid the resource preemption of long flows and reduce the transport delay of short flows. Finally, we conduct extensive experiments based on NS-3 to validate the performance of proposed algorithm in various scenarios, such as only short flow transmitting, long and short flows coexisting, and background traffic existing. Moreover, we measure the completion time of short flows and goodput of long flows with different number of subflows, different concurrent number of short flows, different value of thresholds etc. The experimental results show that the MPTCP-TOASF algorithm can effectively reduce the short-flow completion time while maintain long-flow throughput when long and short flows occur concurrently, thereby improving the mean goodput of network and achieving a great performance enhancement.

The modern mobile devices are typically equipped with multiple network interfaces, e.g., 4G LTE, Wi-Fi, Bluetooth, but the current implementation of TCP can support only a single path at the same time. The Multipath TCP (MPTCP) leverages the multipath feature and provides (i) robust connection by utilizing another interface if the current connection is lost and (ii) higher throughput than single path TCP by simultaneously leveraging multiple network paths. However, if the performance between the multiple paths are significantly diverse, the receiver may have to wait for packets from the slower path, causing reordering and buffering problems. To solve this problem, previous MPTCP schedulers mainly focused on predicting the latency of the path beforehand. Recent studies, however, have shown that the path latency varies by a large margin over time, thus the MPTCP scheduler may wrongly predict the path latency, causing performance degradation. In this paper, we propose a new MPTCP scheduler called, choose fastest subflow (CFS) scheduler to solve this problem. Rather than predicting the path latency, CFS utilizes the characteristics of these paths to reduce the overall flow completion time by redundantly sending the last part of the flow to both paths. We compare the performance through real testbed experiments that implements CFS. The experimental results on both synthetic packet generation and actual Web page requests, show that CFS consistently outperforms the previous proposals in all cases.
