Abstract:Streaming media transmission `has widely used over wireless network. Because of the problem of conventional TFRC mechanism concerning incorrect packet loss rate, when it is applied to mobile congestion networks, the streaming media sever can not get the accurate information of the network condition and thus leading to excessive degrade the sending rate of data. Therefore, an important research issue arises, how to realize loss differentiation between congestion losses and wireless losses and accurate adjustment of network sending rate. Some major congress control protocols including TFRC, AIMD are briefly introduced. This paper propose a mechanism called MTFRC in the base of TFRC ,which appends loss differentiation algorithm. The simulation result shows that MTFRC improves network throughput and the network utilization and guarantee service quality of wireless network streaming media.
