A Congestion Control Mechanism Based on Bandwidth Estimation in Wireless Network
Chao Li · Jisuanji gongcheng · 2004
A new mechanism to improve the throughput of transport control protocol (TCP) in wireless networks is proposed, in which the congestion window is updated by estimated bandwidth. The bandwidth is estimated through the data packet arrival time carried by acknowledgment packets and is used to update congestion window when packet loss occurs, so the transitional congestion control mechanism won't be triggered when link error occurs. The simulation results show that the new mechanism can improve TCP performance in wireless network.
