In this paper, we propose a dynamic OFDMA based subcarrier/power allocation which aims to protect the newly established TCP connections. The proposed allocation utilizes an estimation of the current congestion window of TCP connections to allocate resources so that vulnerable flows with small congestion windows avoid entering packet recovery via retransmission time out. In addition, for the long-lived...
Various cross-layer optimizations have been recently proposed to improve the performance of TCP in wireless networks. In this paper, we propose a dynamic OFDMA based subcarrier/power allocation which aims to constrain the achievable rate on each flow proportionally to the TCP throughput of the corresponding flow. Numerical investigations reveal that the proposed approach significantly increases fairness...
