摘要: Currently, more and research work has been done for the optimization of TCP performance in wireless networks. The majority these schemes proposed are trying to optimize system within single layer. Obviously, jointly considering interaction between transport layer other layers, it may bring improvement performance. In this paper, we propose a novel approach using cross-layer ARQ feedback (CLF-TCP) enhance LANs. Its basic idea is cross-three-layer by utilizing HARQ acknowledgment PHY-layer as MAC-layer implicitly while exploiting information efficient acknowledgement segment delivery. Simulation results show that scheme CLF-TCP not only decrease overhead average transmission delay, but also improve throughput effectively.
