Abstract

The performance of TFRC algorithm is low in the unreliable and dynamic wireless environment. In particular, the packet loss used in TFRC can be caused either by the wireless error or congestion in wireless networks. Based on the analysis of loss differentiate algorithms such as Biaz and ZigZag, we propose the WLD algorithm aiming to differentiate more precisely between the wireless error and congestion loss. The simulation results show WLD algorithm improves remarkably the throughput of streaming in wireless networks, thus improves the performance of congestion control algorithm such as TFRC for media streaming in wireless networks.
