This paper extends the backstepping control strategy to wireless Transmission Control Protocol (TCP) network to solve the Active Queue Management (AQM) problem. Different from the wired network, the uplink and downlink of the wireless network are asymmetric and the packet loss may be caused by congestion and may occurs during the transmission over wireless links. Inspired by the existing backstepping design idea for a wired network model, an adaptive tracking controller is proposed to deal with the congestion problem in wireless network. The uplink and downlink packet losses are estimated by adaptive update laws. The presented method provides satisfactory tracking performance in the network. Meanwhile, the packet loss is small. The simulation results show the feasibility of the proposed method.

基于自适应积分反推的无线TCP/AQM网络拥塞跟踪控制

本文将反步控制策略扩展到无线传输控制协议（TCP）网络，以解决主动队列管理（AQM）问题。与有线网络不同，无线网络的上下行是不对称的，丢包可能是由于拥塞造成的，在无线链路传输过程中可能会发生。受现有有线网络模型反推设计思想的启发，提出了一种自适应跟踪控制器来处理无线网络中的拥塞问题。上行链路和下行链路的丢包率由自适应更新定律估计。所提出的方法在网络中提供了令人满意的跟踪性能。同时丢包小。仿真结果表明了该方法的可行性。
