An Adaptive Redundancy Scheme for TCP with Network Coding

To address the inability of the standard TCP protocol to distinguish between congestive losses and random packet losses produced by the noisy channel, in this paper, the authors propose an adaptive algorithm to dynamically adjust the redundancy factor R of the TPC/NC protocol proposed by Sundararajan et al. by adding some additional functionalities to the original network coding layer. They define a loss differentiation scheme to adjust R, based on the Vegas Loss Predictor and the collective feedback information of ACKs and duplicates ACKs, which are both indicators of the network condition.
