A joint congestion discrimination and channel state rate control scheme over wireless multimedia networks

In this paper, we first investigate the relationship between packet length and packet loss rate in the Gilbert wireless error model. Then we propose a congestion control scheme which can detect the nature of packet losses by sending large and small packets alternately. By means of updating factor an...

Summary:In this paper, we first investigate the relationship between packet length and packet loss rate in the Gilbert wireless error model. Then we propose a congestion control scheme which can detect the nature of packet losses by sending large and small packets alternately. By means of updating factor and loss queue, this proposed scheme can adapt to the changes of network states quickly and improve delivery quality of real-time multimedia stream with a low congestion level. Extensive simulation results demonstrate that the proposed scheme can improve the networks throughput of multimedia transmissions and reduce the congestion loss rate.
