TCP-Forward: Fast and Reliable TCP Variant for Wireless Networks

The congestion control algorithms in TCP (Transmission Control Protocol) may incur inferior performance in a lossy network context like wireless networks. Previous works have shown that random linear network coding can improve the throughput of TCP in such networks, although it introduces extra decoding delay at the destination. In this paper, the authors try to alleviate the decoding delay by replacing random linear network coding with LT codes. Due to the inherent difference between linear network coding and fountain codes, such replacement is not as simple as it sounds.
