The invention discloses an improved request-to-send (RTS) / clear-to-send (CTS)-based method for controlling congestion of a multi-hop wireless network. The method comprises the following steps that: adjacent nodes serving as sending parties or receiving parties in the network issue congestion status information per se; when a transmitting node is in a congestion state, a request-to-send with congestion status (RTSC) request frame having the congestion state sends a request to a target node; and if a receiving node of the RTSC frame is also in the congestion state and receives the request, a clear-to-send with congestion status (CTSC) frame is sent, and the receiving node starts to receive a packet from a sending node. A cache in a node is partitioned into a receiving cache and a sending cache, and the cache service condition and the wireless channel competition degree of the node are considered comprehensively to control the congestion; and a congested receiving party and a congested sending party notify the congestion status information to avoid deadlock, so that the congestion status of the node can be acquired correctly by making a small amount of improvement on the conventionalRTS frame and the conventional CTS frame.
