This application provides a routing communication method and apparatus. In this method, after a node in a wireless ad hoc network determines the next-hop MPR node based on the destination node of the data packet and the OLSR protocol, it also determines the target acceleration node of that next-hop MPR node. Since the minimum of the link rate between the node and the target acceleration node and the link rate from the target acceleration node to the next-hop MPR node is greater than twice the link rate from the node to the next-hop MPR node, forwarding the data packet through the target acceleration node to the next-hop MPR node can effectively improve the data transmission rate of the routing path. Furthermore, the link rate is determined based on the MCS level between nodes, and the MCS level between nodes is obtained through MCS signaling transmitted within the wireless ad hoc network. This eliminates the need to separately send control signaling for transmitting link QoS information, thereby reducing the overhead of transmitting control signaling within the wireless ad hoc network.
