In wireless LAN mesh networks, relay access points (APs) tend to cause buffer overflow due to the decrease in transmission opportunities. This paper proposes a novel congestion control scheme for legacy stations (STAs) accommodated by edge APs. By applying Receiving-Opportunity Control (ROC) to legacy STAs, the proposed scheme can reduce the amount of buffer overflow in mesh access points (MAPs). The proposed scheme is employed depending on the number of MAC frames in the communication buffers. The simulation results show that the proposed scheme achieves improvement in the end-to-end throughput, latency and delivery ratio.
