Abstract :
The equation based TCP-friendly rate control protocol (TFRC) has been proposed to support multimedia applications. In this paper, an analytical approach is proposed for quantifying the performance of equation based TFRC over wireless/Internet integrated networks. Specifically, discrete time Markov chains (DTMC) are developed to analyze the performance of TFRC-controlled multimedia flows, in terms of wireless resource utilization, flow throughput, packet loss rate, and probability of end-to-end delay exceeding a prescribed threshold. It is shown that the maximum number of link layer retransmissions and the required base station buffer size can be determined based on the application´s QoS requirements.
