| 摘 要： | 本文在分析WCDMA的无线链路控制（RLC）层中自动请求重传（ARQ）的实现机制的基础上,综合考虑RLC队列长度、TCP分组到达强度、无线链路层纠错强度以及TCP发送端的应用时延要求等因素,提出了基于模糊逻辑控制的重传控制策略。仿真结果表明,该策略能够有效地提高TCP通过无线网络的吞吐量,高效利用系统无线资源。

| Abstract: | A repeat transmission control strategy based on fuzzy logic to improve TCP throughput in wcdma wireless network is proposed. In which the fuzzy controller consider the RLC queue length, TCP packets arrive rate and the change of the RLC queue, to increase or decrease the retransmission number of RLC protocol data units and to drop the newly arrived TCP packets or not. This strategy is simple and easy to implement. The simulation results show that the Scheme can improve the throughout of TCP in wireless network and improve the utilization of radio resource. |
