TCP-friendly Rate Control Algorithm Based on Wireless-wired Hybrid Network
Di Chen · Jisuanji gongcheng · 2007
Real time multimedia transport protocols in wireless-wired hybrid network are facing new challenges.On the basis of extensive study of characteristics of wireless-wired hybrid network and the current TFRC mechanism,this paper proposes a new TCP-friendly rate control mechanism for real-time traffics.The new mechanism uses Jitter ratio as the signal to differentiate congestion losses and wireless link losses to adjust TFRC’s rate control algorithm.Extensive simulations on NS-2 verify that the new mechanism has better performance than TFRC as well as keeps reasonable friendliness to TCP flows.
