“…The advantage of DCCP is that no extra messages are needed because the protocol has its own acknowledgement system. Some other approaches describe methods that include categorizing groups of packets in order of importance (Rhee, 1998;Zheng and Atiquzzaman, 2002). It takes advantage of the motion prediction loop employed in most motion compensation based codecs.…”

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.

although multimedia applications have very stringent bandwidth, delay and loss requirements. In mobile environment the limited bandwidth and the higher error rate arise as an obstacle of its popularity. In many cases retransmission-based error recovery can be an attractive solution to improve the quality of the video stream, because it requires minimal network bandwidth and processing cost. In this paper we propose a content-aware selective retransmission scheme which allows the retransmission of all packets when the risk of congestion is low, but as it rises the retransmission is disabled step-by-step, but not all at once, in order of packet importance. In this work the heterogenity of H.264 streams were utilized for the determination of packet importance. The advantage of this transmitter controlled procedure is that all the needed information is available at the source due to DCCP transport protocol and its congestion control algorithm. The effectiveness of the proposed method was examined in Ns2 network simulator. IntroductionReal-time multimedia applications are gaining prominence on the Internet. These applications are not only used in reliable wired networks but also in wireless environment where the obstacles of the expansion are the higher bit error ratio of the radio link and the limited bandwidth of the mobile links. The loss of packets in a video frames leads not only to reduce the quality of video but also results in the propagation of distortion to successive frames, because interframe-video compression algorithms such as MPEG exploit temporal correlation between frames to achieve higher compression. To minimize the end-to-end packet loss ratio the packet loss should be either prevented or subsequently handled.
