Buffer-Driven Rate Control and Packet Distribution for Real-Time Videos in Heterogeneous Wireless Networks

Abstract

Video transmission bandwidth can be substantially increased by concurrent transmission through multiple radio interfaces introduced by heterogeneous wireless networks. However, delivering high-quality real-time videos with stringent end-to-end delay constraints is still challenging due to the time-varying multipath channel status. Thus, to integrate available multipath bandwidth and guarantee low end-to-end delay, this paper investigates a real-time concurrent multipath video transmission scheme in heterogeneous access networks. First, we present a multipath buffer analysis model (MBAM) to derive the lower and upper bounds of the target video frame bits. Second, given the low-latency and received video quality smoothness, we propose a buffer-driven rate control and packet distribution (BRCPD) algorithm aided by frame-level rate control and multipath transmission buffer awareness based on MBAM. Finally, we implement the proposed application-layer solution BRCPD algorithm in a real-world testbed. The experiment results verify that different from existing multipath video transmission schemes, the proposed algorithm is able to leverage the MBAM-based frame-level rate control to guarantee the target low end-toend delay. In particular, the BRCPD algorithm is able to guarantee an overdue loss rate of less than 5% under strictly limited delay constraints (250 ms) in the real-world testbed.

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

“…Chen et al 15 established the packet distribution and buffer‐driven rate control for real‐time video of the heterogeneous wireless network. In the heterogeneous access networks, the real‐time coincident multichannel video broadcast system was employed.…”

“…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.…”

Cross Layer Based Dynamic Traffic Scheduling Algorithm for Wireless Multimedia Sensor Network

“…However, the packet rate control problem was not considered in MBAM analysis. Therefore, by taking the quality of received video and low-latency a Buffer-driven Rate Control and Packet Distribution (BRCPD) algorithm [16] was proposed in order to achieve the fairness rate control and buffer awareness of multipath transmission on basis of MBAM.…”
