Abstract

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