A Wireless TCP-friendly Rate Control Mechanism for Streaming Delivery
Zongkai Yang · Journal of Chinese Computer Systems · 2007
Considering statistic features of packet loss due to wireless error and congestion events,this paper proposes a wireless TCP-friendly rate control (WTFRC) equation for streaming media delivery based on loss differentiation. Besides, a practical rate control mechanism is constructed. Our architecture includes sender functionality on content server or proxy side and receiver functionality on client side. The former is in charge of loss events differentiation, packet loss ratio (PLR) and receiving rate estimation. The latter is in charge of round-trip time (RTT) estimation, sending rate evaluation and adjustment. Simulation results demonstrate that higher throughput, better fairness and smoother sending rate can be achieved by our proposed mechanism.
