Abstract
The optimal direction-based flooding method for relaying a broadcast message for mobile ad-hoc networks comprises (a) an original source node selecting a first relay node; (b) selecting a message relaying direction into an area divided by a predetermined interval; (c) relaying the broadcast message by selecting the first relay node set for each message relaying direction; and (d) selecting a next relay node and relaying the broadcast message received by the previously selected relay node. Duplicated broadcast message transmissions, and competition and collision among the nodes to obtain transmission media, are reduced by transmitting the broadcast message using a minimum number of nodes in a mobile ad-hoc network including nodes having limited resources.
