AB  - Rate control is an important issue in video streaming application for both wired and wireless
networks. A widely accepted rate control method in wired networks is TCP Friendly Rate Control (TFRC). TFRC assumes that packet loss in wired networks is primarily due to congestion and as such is not be applicable to wireless networks in which the bulk of packet loss is at the physical layer. Hence the multiple TFRC
Connections (MULTFRC) are being used as an existing approach, which is an end-to-end based solution to
this problem. By opening appropriate number of TFRC connections, MULTFRC not only avoids modifications
to the network infrastructure but also results in full utilization of the wireless bandwidth. However MULTFRC
suffers form underutilization of resources and loss of granularity in number of connections. To address these
drawbacks, we propose a modified TFRC rate control scheme that combines multiple connections to one
connection and improves the performance of streaming over wireless networks. We name our rate control
scheme as CTFRC (Consolidated TFRC) with loss handling mechanism. We carried out NS-2 simulations to
compare the performance of MULTFRC and our own rate control scheme.
