Abstract : Rate control is an important issue in video streaming applications for both wired and wireless networks. A widely accepted rate control method in wired networks is TCP friendly equation based rate control [1], i.e. TFRC. However, it assumes that packet loss in wired networks is primarily due to congestion, and as such is not applicable to wireless networks in which the bulk of packet loss is due to error at the physical layer. In this paper, we propose using multiple TFRC connections as an end-to-end rate control solution for wireless video streaming application. We show that this approach not only avoids modifications to the network infrastructure or network protocol, but also results in full utilization of the wireless channel. NS-2 simulations and experiments over 1xRTT CDMA wireless data network are carried out to validate, and characterize the performance of our proposed approach.
