Abstract: A method for relaying a route request RREQ message by an intermediate node which is connected with at least one node using a tree topology in a mobile communication system including a destination node and a source node which sends the RREQ message to the destination node via at least one intermediate node, to thus establish an optimal route for communications. The RREQ message is received along the route other than the tree route, and the first information is updated using its information. The intermediate node relays to a next intermediate node the RREQ message containing the updated first information.
