METHOD FOR ROUTE SETUP BY EXPLOITING MEDIUM ACCESS CONTROL WITH MULTIPLE RATE IN MOBILE AD-HOC NETWORK

A method for setting a route by using MAC with multiple rates in an MANET is provided to transmit packets based on a higher-speed route and prevent effectively the deterioration of capability caused by additional control information for setting the high-speed route. A method for setting a reactive route by using MAC with multiple rates in an MANET(Mobile Ad-hoc Network) comprises the following steps of: enabling a source MN(Mobile Node)(10) to broadcast a route request message for setting a route to a destination MN(50)(S210,S211); enabling a plurality of MNs, which are disposed in the middle and receive the broadcasted route request message, to process a received message and broadcast the processed message again(S214,S215); enabling the destination MN to process the route request message broadcasted through the plural MNs(S218); and enabling the destination node to transmit the route response message to the source MN with a unicast method(S220).
