摘要：Disclosed is a method for setting up a route path between a source node and a destination node through route discovery in a mobile ad hoc network. The source node transmits a RREQ message to the destination node, and the destination node transmits a RREP message to the source node in response to the RREQ. A first intermediate node having failed to transmit the original RREP stores the original RREP, generates a PRREQ message, and transmits the generated PRREQ to neighbor intermediate nodes. If an ID of the PRREQ and an original IP address included in the received PRREQ are identical to an ID and an original IP address of the RREQ received from the source node, a second intermediate node receiving the PRREQ generates a PRREP message corresponding to the PRREQ and transmits the PRREP to the first intermediate node. If a partial route path is set up between the first intermediate node and the second intermediate node as the first intermediate node receives the PRREP, the first intermediate node transmits the original RREP via the partial route path. Then the source node receives the original RREP, and completes setup of the route path.
