Study of congestion control mechanism for wireless networks using expert control

The application of TCP over wireless networks is a challenging work due to high bit error rates and fading and handoff. This paper presents a congestion control mechanism for wireless networks based on expert control, which makes sure the state of TCP connection and differentiates between wireless link errors and network congestion in terms of the inference. Wireless link errors as well as congestion in the wired network are separately controlled. The simulation results show that this method can strengthen the congestion and random errors processing capability in real time and improve the throughput of the network, and this control scheme is more robust than normal TCP.
