Performance Enhancement of Multimedia Data Transmission by Adjusting Compression Rate

The rapid growth of wireless communication technology has spurred various mobile applications. In this paper we propose a scheme which can improve the PSNR of multimedia data transmission using the RTP/RTCP. It is achieved by adjusting the compression rate according to the packet loss rate, delay, or jitter in the network. The NS-2 simulation reveals that the proposed approach shows a significant improvement over the conventional scheme of fixed compression rate. Particularly, it turns out that adjusting based on jitter is more effective than with the other two factors.
