Channel reservation method for multi-hop transmission of wireless ad hoc network

The invention provides a channel reservation method for multi-hop transmission of a wireless ad hoc network, which relates to the technical field of wireless ad hoc networks, and comprises the following steps: S1, a source node acquires an IP address of a destination node and an MAC address of a first hop node, and sends an RTS message to the first hop node; s2, the first-hop node obtains the MAC address of the second-hop node, sends a CTS message, completes channel reservation of the first-hop node and transmits data; s3, the second hop node receives the CTS message and sends a busy tone signal to complete channel reservation of the second hop node; s4, the first hop node identifies the busy tone signal and sends an RTS message to the second hop node; s5, the second hop node stops sending the busy tone signal, obtains the MAC address of the next hop node and sends a CTS message, and the first hop node receives the CTS message and transmits data to the second hop node; and iterating S3 to S5.
