Abstract

In this paper, we propose a measurement based TCP-friendly rate control (TFRC) that adjusts the coding rates according to the channel characteristics of the wireless-to-wired network. To avoid the throughput degradation of multimedia flows traveling through wireless link, the proposed rate control system employs a new loss differentiation algorithm using packet loss statistics. This method can eliminate the effect of wireless losses in flow control and substantially reduce the abrupt quality degradation of the video streaming caused by the unreliable wireless link status. Experimental results show that the proposed rate control system produces the TCP-friendly rates while sharing the backbone bandwidth with TCP flows. Moreover, error resilient coding methods can be easily applied to the proposed TFRC by using the packet loss statistics.
