Mobile devices equipped with multiple network interfaces can increase their throughput by making use of parallel transmissions over multiple paths and bandwidth aggregation, enabled by the stream control transport protocol (SCTP). However, the different bandwidth and delay of the multiple paths will determine data to be received out of order and in the absence of related mechanisms to correct this, serious application-level performance degradations will occur. This paper proposes a novel quality-aware adaptive concurrent multipath transfer solution (CMT-QA) that utilizes SCTP for FTP-like data transmission and real-time video delivery in wireless heterogeneous networks. CMT-QA monitors and analyses regularly each path's data handling capability and makes data delivery adaptation decisions to select the qualified paths for concurrent data transfer. CMT-QA includes a series of mechanisms to distribute data chunks over multiple paths intelligently and control the data traffic rate of each path independently. CMT-QA's goal is to mitigate the out-of-order data reception by reducing the reordering delay and unnecessary fast retransmissions. CMT-QA can effectively differentiate between different types of packet loss to avoid unreasonable congestion window adjustments for retransmissions. Simulations show how CMT-QA outperforms existing solutions in terms of performance and quality of service.Index Terms-Quality awareness, concurrent multipath transfer, SCTP, heterogeneous wireless network, video delivery Ç 1 INTRODUCTION I N recent years, wireless communication technologies have experienced an extremely rapid development. Supported by the latest technological advances, mobile devices have also become smarter and many are already equipped with multiple network interfaces [1]. Large number of increasingly complex services and applications in various areas of interest, including business and entertainment, are widely offered to users of these mobile devices over the wireless networks, making use of their ubiquitous access support [2], [3], [4]. However, the heterogeneity of the wireless network environment requires additional solutions to enable smooth high-quality service provisioning. The stream control transmission protocol (SCTP) [5], [6], [7], with its multihoming feature [8] and SCTP's dynamic reconfiguration extension (mSCTP) [9] are very promising protocols to support efficient data transmission, including seamless handover in heterogeneous wireless networks.Concurrent multipath transfer (CMT) uses SCTP's multihoming feature to concurrently distribute data across multiple independent end-to-end paths in a multihomed SCTP association [10], [11]. Mobile devices equipped with multiple network interfaces can achieve bandwidth aggregation by using CMT to improve data throughput, bandwidth resource utilization, and system robustness [12]. Fig. 1 illustrates CMT usage in a heterogeneous wireless environment. It shows how a smart phone can concurrently use both 3G/4G and WiFi access links to communicate with the server. It...

“…For example, Stegel et al [10] proposed solutions on how to provisioning SCTP multihoming in converged IP-based multimedia environment. Huang and Lin [11] proposed a partially reliable-concurrent multipath transfer (PR-CMT) protocol for multimedia streaming in order to improve the throughput and video quality degrade. In our previous work, we designed a novel Evalvid-CMT platform [3,4] to investigate and evaluate the performance of CMT for real-time video distribution, and then a meaningful suggestion was pointed out on which strategies for real-time video concurrent multipath transmissions.…”

Background Traffic-Based Retransmission Algorithm for Multimedia Streaming Transfer over Concurrent Multipaths

International Journal of Digital Multimedia Broadcasting

et al. 2012

The content-rich multimedia streaming will be the most attractive services in the next-generation networks. With function of distribute data across multipath end-to-end paths based on SCTP's multihoming feature, concurrent multipath transfer SCTP (CMT-SCTP) has been regarded as the most promising technology for the efficient multimedia streaming transmission. However, the current researches on CMT-SCTP mainly focus on the algorithms related to the data delivery performance while they seldom consider the background traffic factors. Actually, background traffic of realistic network environments has an important impact on the performance of CMT-SCTP. In this paper, we firstly investigate the effect of background traffic on the performance of CMT-SCTP based on a close realistic simulation topology with reasonable background traffic in NS2, and then based on the localness nature of background flow, a further improved retransmission algorithm, namedRTX_CSI, is proposed to reach more benefits in terms of average throughput and achieve high users' experience of quality for multimedia streaming services.

“…Although CMT-based multimedia streaming has gained much attention and resulted in many peer-reviewed publications [5][6][7][8][9][10][11][12][13], there is still significant ongoing work addressing many challenges. The classic CMT strategy mainly uses a round-robin method to split SCTP packets over all available paths in an equal-share way to achieve parallel transmissions and bandwidth aggregation.…”

CMT‐CQA: Cross‐layer QoS‐aware adaptive concurrent multipath data transfer in heterogeneous networks

et al. 2014

Stream control transport protocol (SCTP)‐based concurrent multipath transfer (CMT) can help multi‐homed devices to increase their throughput by making use of parallel transmissions over multiple paths and bandwidth aggregation. However, if CMT cannot identify wireless error, it cannot really achieve the desired performance. Furthermore, if CMT only utilizes all available paths for data delivery, it will undoubtedly degrade application‐level performance since the asymmetric paths may involve large quality differences. This paper proposes a novel cross‐layer quality‐of‐service (QoS)‐aware adaptive CMT (CMT‐CQA) with the following aims: (i) to provide an adaptive ‘CMT‐to‐partial CMT’ adjustment strategy for efficient bandwidth aggregation by jointly considering transport layer QoS, MAC layer QoS, and path history information; (ii) to address an enhanced congestion window (cwnd) fast recovery mechanism to reduce bursty transmission in multi‐homed wireless network environments where fail‐over occurs frequently; and (iii) to introduce a proper multimedia transmission behavior to improve users' quality of experience (QoE) for multimedia streaming service. Simulation results show that CMT‐CQA outperforms the existing CMT solutions in terms of performance and QoS. © 2014 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc.
