Self-adaptive Scheme to Adjust Redundancy for Network Coding with TCP

Network coding has emerged as an important potential approach to improve the robustness and efficiency of data transmission over lossy wireless network. TPC/NC protocol proposed by Sundararajan et al incorporating network coding into TCP by online coding, TCP/NC has the advantage of naturally adding network coding to current network systems and masking non-congestion packet losses from the congestion control algorithm, However, in TCP/NC the values of redundancy factor R can’t be adapted based on the characteristics of the underlying channel.
