چکیده
In this paper we present a novel selective retransmission scheme, based on congestion control algorithm. Our method efficient in narrowband networks for multimedia applications which demand higher bandwidth. Multimedia applications are becoming increasingly popular in IP networks, while in mobile networks the limited bandwidth and the higher error rate arise in spite of its popularity. These are restraining factors for mobile clients using multimedia applications such as video streaming. In some conditions the retransmission of lost and corrupted packets should increase the quality of the multimedia service, but these retransmissions should be enabled only if the network is not in congested state. Otherwise the retransmitted packet will intensify the congestion and it will have negative effect on the audio/video quality. Our proposed mechanism selectively retransmits the corrupted packets based on the actual video bit rate and the TCP-Friendly Rate Control (TFRC), which is integrated to the preferred DCCP transport protocol.

Adaptive Broadband Wideo Streaming for IPTV Wireless Access
Broadband wireless access supports mobile applications, which may soon extend to Internet Protocol TV (IPTV). IPTV streaming from a localized server is likely to be across a wired path through a metro network before crossing the wireless link. In this scenario, the paper proposes Broadband Video Streaming (BVS), which enhances UDP transport with a single, negatively acknowledged, lost packet re...
متن کاملA CLIENT−DRIVEN SCALABLE CROSS−LAYER RETRANSMISSION SCHEME FOR 3G VIDEO STREAMING (FriAmPO1)
The wireless channel is highly time−varying where packet losses often occur during the fading or lossy handovers. In order to avoid unaccepted quality degradation of video streaming over 3G cellular networks, we propose and analyze a novel client−driven scalable cross−layer (CSC) retransmission scheme. Considering the perceptual importance of different video partitions under the real−time and b...
متن کاملAdaptive Video Transmission Over A Single Wireless Link
In this paper, we propose an adaptive priority-based selective repeat ARQ (PSR-ARQ) transmission scheme for transmitting video over a single-hop lossy wireless link. If transmission errors occur in a lower layer of the video, the errors propagate to all the higher layers of related frames resulting in significant degradation of the video quality at the receiver. Due to the limited channel bandw...
متن کاملLow-latency streaming of pre-encoded video using channel-adaptive bitstream assembly
Today’s Internet video streaming systems employ buffering and retransmission to guarantee the correct reception of each packet. This leads to high latency in media delivery. In this paper, we present an efficient low-latency Internet video streaming system that does not require retransmission of lost packets. We pre-store multiple representations of certain frames on the server such that a repr...
متن کاملRobust video streaming over wireless LANs using multiple description transcoding and prioritized retransmission
Video transport over wireless Local Area Networks (LANs) usually suffers from signal fading, noise interference, and network congestion, leading to time-varying packet loss rate and fluctuating effective bandwidth. We propose in this paper an adaptive error control scheme to adaptively insert error-resilience features into a compressed video in the media gateway which serves roaming clients. Ou...
