Lossy channels

TCP over wireless networks is challenging due to random losses and ACK interference. Although network coding schemes have been proposed to improve TCP robustness against extreme random losses, a critical problem still remains of DATA–ACK interference. To address this issue, we use inter-flow coding between DATA and ACK to reduce the number of transmissions among nodes. In addition, we also utilize a ‘‘pipeline’’ random linear coding scheme with adaptive redundancy to overcome high packet loss over unreliable links.
