Real-time video streaming over multipath in multi-hop wireless networks

Given the limited wireless link throughput, high loss rate, and varying end-to-end delay, supporting video applications in multi-hop wireless networks becomes a challenging task. Path diversity exploits multiple routes for each session simultaneously, which achieves higher aggregated bandwidth and potentially decreases delay and packet loss. Unfortunately, for TCP-based video streaming, naive load splitting often results in inaccurate estimation of round trip time (RTT) and packet reordering. As a result, it can suffer from significant instability or even throughput reduction, which is also validated by our analysis and simulation in multi-hop wireless networks. To make real-time TCP-based streaming viable over multi-hop wireless networks, we propose a novel cross-layer design with a smart traffic split scheme, namely, multiple path retransmission (MPR). MPR differentiates the original data packets and the retransmitted packets and works with a novel QoS-aware multi-path routing protocol, QAOMDV, to distribute them separately. MPR does not suffer from the RTT underestimation and extra packet reordering, which ensures stable throughput improvement over single-path routing. Through extensive simulations, we further demonstrate that, as compared with state-of-the-art multi-path protocols, our MPR with QAOMDV noticeably enhances the TCP streaming throughput and reduces bandwidth fluctuation, with no obvious impact to fairness.

“…Wireless channel utilization is considerably improved, with a minimal impact on end-toend delay. As a trade-off, there is an increase in start-up delay arising from the need to avoid possible buffer underflow, though this is smaller compared to TCP-based streaming, when large buffers are normally employed [8] to cater for the possibility of repeated retransmissions. For example, in [9] a buffer size of 10 s was required to counter wireless burst errors.…”

Abstract-Streaming a single video over multiple TCPFriendly Rate Control (TFRC) connections is a way of separately coping with both wireless channel losses and traffic congestion, without the need for cross-layer intervention or retransmission delay at the data-link layer. At the same time, the wireless channel is properly utilized, as throughput improves with an increasing number of connections. Nevertheless over IEEE 802.16e (mobile WiMAX), tuning is needed to select the number of connections and the Time Division Duplex (TDD) frame size. The paper assesses the impact on video quality of packet drops due both to channel loss over a WiMAX access link and router buffer overflow across an all-IP network, consisting of broadband wireless access and core network. The paper also considers end-to-end delay and start-up delay when employing several connections. Results show that provided the TDD frame size is selected appropriately then using multiple connections preserves video quality and improves wireless channel utilization, with a minimal impact on end-to-end delay. As a trade-off, there is an increase in start-up delay arising from the need to avoid possible buffer underflow.

“…In a receiver oriented approach [16], the authors evaluate multimedia streaming with TCP, and conclude that buffering at the client can handle the retransmission delays and the congestion control induced throughput variations of TCP. Another receiver-driven technique for video streaming, that introduced the idea of receiver-based delay control (RDC), was presented in [13]. The idea is that a receiver delays TCP acknowledgments based on feedback from routers.…”
