Abstract A cross-layer TCP fairness optimization model in mobile WiMAX is proposed, under which a TCP protocol, cross-layer TCP, is designed. The rate information from link layer of the mobile nodes and the strategy of preallocation bandwidth for ACK packet at the base station are both used to improve the quality of service of the downlink nodes, which gives throughput fairness to the downlink nodes and the uplink nodes. Experiments show that cross-layer TCP protocol can improve the fairness of the downlink nodes under the same system throughtput.
