  • the k hop cooperative video Streaming Protocol using h 264 svc over the hybrid vehicular networks
    IEEE Transactions on Mobile Computing, 2014
    Co-Authors: Chao-hsien Lee, Chia-ching Yang, Chung-ming Huang, Hsiao-yu Lin
    Abstract:

    When a number of persons, e.g., a family or a group of friends, drive their vehicles for a trip together, they can form a fleet of vehicles and share their network resources during their trip. Let one member want to watch a video from the Internet. He may not have high resolution or video quality due to his limited 3G/3.5G bandwidth to the Internet. The cooperative video Streaming scenario allows the requested member to ask other members of the same fleet to download video cooperatively. In other words, other members can help to download parts of the video from the Internet and then forward video data to the requested member hop by hop through the ad-hoc network. This work proposes the k-hop cooperative video Streaming Protocol using H.264/SVC over the hybrid vehicular networks which consist of 3G/3.5G cellular network and Dedicated Short-Range Communications (DSRC) ad-hoc network. In order to smooth video playback over the DSRC-based ad-hoc network, this work proposes: (1) one Streaming task assignment scheme that schedules the Streaming task to each member over the dynamic vehicular networks, and (2) packet forwarding strategies that decide the forwarding sequence of the buffered video data to the requested member hop by hop. Finally, we utilize the network simulator version 2 (NS2) to simulate the proposed Protocol. Based on the simulation results, the proposed scheme can estimate the assignment interval adaptively and the playback priority first (PPF) strategy has the best performance for the k-hop video forwarding over the hybrid vehicular networks.

  • Experimental study of QoE improvements towards adaptive HD video Streaming using flexible dual TCP-UDP Streaming Protocol
    Multimedia Systems, 2020
    Co-Authors: Kevin Gatimu, Arul Dhamodaran, Taylor Johnson
    Abstract:

    The Flexible Dual TCP-UDP Streaming Protocol (FDSP) combines the reliability of TCP with the low latency of UDP, thus providing transport layer improvements towards maintaining high QoE of multi-bitrate videos in adaptive Streaming. FDSP delivers the more critical parts of the video data via TCP and the rest via UDP. FDSP also uses Bitstream Prioritization (BP), a sliding scale that determines the proportion of video data that is sent using TCP. BP can be adjusted according to the level of network congestion. FDSP-based Streaming reduces total rebuffering time by over 90%, and rebuffering instances by 50% in many cases compared to TCP-based Streaming. At the same time, packet loss reduces by over 75% for most BP levels compared to UDP-based Streaming. In addition, FDSP-based Streaming is potentially more suitable for adaptive Streaming compared to the state-of-the-art TCP-based HTTP Adaptive Streaming (HAS), which is often plagued by high latency and high bandwidth requirements. In contrast, FDSP requires significantly less bandwidth than TCP in congested networks while exhibiting more stable client buffers.

  • CCNC - Experimental study of low-latency HD VoD Streaming using flexible dual TCP-UDP Streaming Protocol
    2018 15th IEEE Annual Consumer Communications & Networking Conference (CCNC), 2018
    Co-Authors: Kevin Gatimu, Arul Dhamodaran, Taylor Johnson, Ben Lee
    Abstract:

    The Flexible Dual TCP-UDP Streaming Protocol (FDSP) combines the reliability of TCP with the low latency characteristics of UDP. FDSP delivers the more critical parts of the video data via TCP and the rest via UDP. Bitstream Prioritization (BP) is a sliding scale that is used to determine the amount of TCP data that is to be sent. BP can be adjusted according to the level of network congestion. FDSP-based Streaming achieves lower rebuffering time and less rebuffering instances than TCP-based Streaming as well lower packet loss than UDP-based Streaming. Our implementation and experiments on a real testbed shows that FDSP with BP delivers high quality, low-latency video, which is especially suitable for live video and subscription-based video.

  • Analysis of optimum substream lengths for dual TCP/UDP Streaming of HD H.264 video over congested WLANs
    2017 14th IEEE Annual Consumer Communications & Networking Conference (CCNC), 2017
    Co-Authors: Arul Dhamodaran, Kevin Gatimu
    Abstract:

    Flexible Dual-TCP/UDP Streaming Protocol (FDSP) is a new method for Streaming H.264-encoded High-definition (HD) video over WLANs. FDSP Streaming is done in sequential video segments or chunks called substreams. Substreams are typically used in HTTP/TCP Streaming for efficient switching between different quality levels of video. However, in FDSP, substream lengths are used to control the amount of TCP data that needs to be sent prior to the playback of that substream. Substream length choice also affects the corresponding amount of UDP data. This paper presents an analysis of substream length modification in the context of FDSP. Our results show that as substream length increases, TCP rebuffering time decreases while the number of TCP rebuffering instances increases. However, our results also show that substream length alone does not have a clear correlation with UDP packet loss.
