<p>The present invention relates to an apparatus for topology management in a mobile Ad-Hoc network and a method thereof. The apparatus for topology management comprises a source node transmitting packet data, a destination node receiving the packet data, at least one relay node positioned on a transmission link between the source node and the destination node to deliver the packet data, a plurality of link nodes connecting the nodes and forming the transmission link, and at least one unmanned unit moving to a link node with the lowest packet delivery ratio among the link nodes to add a new link node according to a request from the relay node or the destination node if the overall data transmission ratio of the transmission link is below a preset reference data transmission ratio. In addition, the apparatus performs a step of adding or removing at least one unmanned unit operating as a mobile relay to or from a link node with the lowest packet delivery ratio among the link nodes existing between the source node and the destination. According to the present invention, it is possible to maintain data transmission quality between nodes at a constant level, whereby the quality of the transmission link between the source node and the destination node can be maintained above a baseline that a user wants.</p> |
