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

Abstract

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.

Cognitive Adaptive Access-Control System for a Secure Locator/Identifier Separation Context

“…Our future work will embed the DHT-ADS into the CAAC then evaluate and analyze the performance of the CAAC system. Moreover, since the locator/identifier separation is a good standard selection for multi-homed network as mentioned in Section 1, thus our future work will focus on extending the CAAC for optimizing the communication capability with our previous work [18][19][20][21][22][23][24][25][26], and further evaluate and analyze its performance with realistic network traffic.…”

Adaptive Fast Retransmission With Respect to Receiver Buffer (Rbuf) Space in Simultaneous Multipath Transmission (Smt)

“…On the other hand, the cross-layer solutions provide flexibility of getting feedback from any layer with the incentive of performance optimization. Cao et al presented a cross-layer approach for QoS-aware adaptive CMT (CMT-CQA) in which slowest trouble maker path is removed from multipath transmission to avoid aggregated bandwidth degradation [8]. The choices of best paths are made using cross layer paths history and medium access control (MAC) layer quality of service (QoS) information.…”
