Flow Control Over Wireless Network and Application Layer Implementation

— Flow control, including congestion control for data transmission, and rate control for multimedia streaming, is an important issue in information transmission in both wireline and wireless networks. Widely accepted flow control methods in wireline networks are TCP [1] for data, and TCP Friendly Rate Control (TFRC) [2] for multimedia. Kelly [3] [4] has laid down theoretical framework for TCP in wireline networks demonstrating its optimality, fairness, and stability. However, TCP and TFRC both assume that packet loss in wireline networks is primarily due to congestion, and as such, are not applicable to wireless networks in which the bulk of packet loss is due to errors at the physical layer. In this paper we first show flow control in the wireless networks can be formulated as the same concave optimization problem Kelly defined in the wireline networks. TCP and TFRC in the wireless networks pursue the optimal solution using inaccurate feedback. All existing approaches to this TC...
