High-Frame-Rate (HFR) video technology is becoming widely implemented in popular multimedia applications (e.g., Youtube and cloud gaming) to provide smooth viewing experience. Meanwhile, Transmission Control Protocol (TCP) is pervasively adopted as the transport-layer solution for video communications to achieve firewall traversal and network-friendliness. However, it is severely challenging to effectively deliver real-time HFR video over TCP: 1) HFR video streaming is featured by high transmission rate, enhanced frame density and stringent delay constraint; 2) the packet retransmission and congestion control mechanisms in TCP may cause frequent throughput fluctuations and deadline violations. Motivated by addressing these critical issues, this research presents an application-layer FEC (Forward Error Correction) framework dubbed ROCHET (RaptOr Coded HFR VidEo over TCP). First, we develop a mathematical model to analyze the frame-level distortion of systematic Raptor codebased HFR video communication over TCP in wireless networks. Second, we propose a joint approximate distortion estimation and Raptor coding adaption solution to minimize the sum of total distortion. The proposed ROCHET is able to effectively leverage unequal error protection and TCP state analysis to enhance streaming video quality. We conduct the performance evaluation through extensive emulations in Exata involving real-time HFR video encoded with H.264 codec. Compared with the existing FEC coding schemes, ROCHET achieves appreciable improvements in terms of video Peak Signal-to-Noise Ratio (PSNR), goodput, and frame success rate. Thus, ROCHET is recommended for TCPbased HFR video transmission over wireless networks.

“…Evidence from the telecommunications industry (Tappayuthpijarn, Liebl, Stockhammer, & Steinbach, 2009) shows that NGMNs present a major advantage for operating networks, given the increase in digital traffic (Mok, Chan, & Chang, 2011). Some research shows that mobile videos will cause mobile data traffic to rise by more than 66%, expanding possibly 39 times, in the five years 2014 to 2019 (Freris, Hsu, Singh, & Zhu, 2013). Figure 1 shows mobile growth around the world, which is challenging systems' capability and clients' connectivity.…”

The growth in users streaming videos on the Internet has led to increased demand for improved video quality and reception. In next generation networks (NGNs), such as 3G and 4G LTE, quality of service (QoS) implementation is one of the ways in which good video quality and good video reception can be achieved. QoS mainly involves following an industry-wide set of standard metrics and mechanisms to achieve high-quality network performance in respect of video streaming. Adopting routing and communication protocols is one way QoS is implemented in NGNs. This article describes QoS of bit rate video streaming, and QoS performance analysis of video streaming, in relation to the main network transport protocols, namely transmission control protocol (TCP) and user datagram protocol (UDP). A simulation test bed was set up using OPNET modeller 14.5. In this setup, a network topology was created and duplicated three times, in order to configure two simulation scenarios (each using the distinct protocols), and a third simulation scenario using both protocols in hybrid form. The findings in the simulations indicated that, when a network is configured with both TCP and UDP protocols in video streaming, there is a positive change in the degree of performance in terms of the QoS of videostreaming applications, unlike when the protocols are used independently.Keywords quality of service (QoS), bit rate video streaming, QoS routing, transmission control protocol (TCP), user datagram protocol (UDP)

Demand for wireless data bandwidth has been increasing explosively so that the present licensed cellular networks (LCNs) themselves are no longer competent to provide high quality service to the users at a reasonable cost. In this paper, we propose a cost-effective system, called cognitive multihoming (CM), that enables high quality service and at the same time incurs low cost. The proposed system considers a cellular base station with added cognitive radio (CR) functionality. The heterogeneous resources are organized into a single centrally-managed virtual system to allocate the heterogeneous users with varying quality and cost constraints. Multiple multihoming-capable heterogeneous users request downlink unicast data from the system. Transmissions to these users are performed simultaneously via LCN and CR network (CRN). This cooperative approach aids lowering service cost to the users. The possibility of loss in quality of service is mitigated by optimally distributing the traffic load between LCN and CRN, based on the users' rate requirements. To evaluate the CM performance we consider a benchmark system with the same total channel resource from LCN and CRN, where a user is served via either LCN or CRN depending on the users quality and cost preferences. Numerical results show that, on average the network utility of the proposed system is nearly 17% higher than the benchmark.
