Device‐centric data reordering and buffer management for mobile Internet using Multipath Transmission Control Protocol

Abstract

Summary Today's smart mobile devices (SMDs) are equipped with multiple interfaces, powerful processors, and workable battery power. Such SMDs are making future networks truly heterogeneous. In such future mobile networks, there is an opportunity to utilize the SMD's interfaces concurrently. There are challenges in the implementation of this idea, because regular TCP does not support path aggregation, multihoming, and full‐mesh networking. The multipath TCP (MPTCP) is a power set of TCP extensions that provide the subflows on each SMD's interface. The MPTCP runs over the existing infrastructure of the TCP by using TCP options field, without compromising the normal TCP functions. An end‐to‐end data scheduling and data reordering are important issues in such mobile Internet across multiple subflows of MPTCP. In this paper, we proposed the mechanisms for multipath scheduling, device‐centric data reordering, and buffer management to achieve concurrent utilization of SMD's LTE and Wi‐Fi interfaces for video stream applications on mobile Internet. We modeled the approaches for multipath scheduling and reordering to ensure the improved utilization of SMD's interfaces and decrease the buffer usage. The proposed approaches consider the outstanding data bytes and latency of each MPTCP subflow. The proposed approaches are tested on a MPTCP‐supported testbed, and captured data are analyzed in terms of gross throughput, buffer usage, end‐to‐end performance, and path utilization of subflows on SMD's LTE and Wi‐Fi interfaces. The performance is evaluated and compared with related state‐of‐the‐art approaches, and significant improvement is observed.

An efficient congestion control in multimedia streaming using adaptive BRR and fuzzy butterfly optimization

“…Kumar et al 17 elaborated buffer management with mobile internet and device‐centric data rearranging by utilizing multipath transmission control protocol (MPTCP). The methods for device‐centric data reordering, multipath scheduling, and buffer management were achieved at the same time using smart mobile devices (SMD) and the Wi‐Fi links to the video stream application for mobile internet.…”

“…Single path delay constitutes two different types of delay namely the propagation delay and queueing delay that is employed in determining the dynamics of the router occupied by the buffers. The delay rate of the proposed approach is compared with various other transmission network techniques like delay BBR (D-BBR), 12 buffer driven rate control and packet distribution (BRCPD), 15 MPTCP, 17 HAS technique. 18 The experimentation is conducted to determine the single path delay rate and from the graphical plottings, it is emphasized that the delay value is dropped with respect to the index rate of 4 and 5 and the overall transmission delay rate is minimum for the proposed approach in comparison with other techniques.…”
