| 1. A method for controlling a unidirectional link connection in a mobile ad hoc network formed by a plurality of mobile nodes
comprising:
(a) each mobile node sensing the unidirectional link when the unidirectional link is generated because of a difference between
transmission powers;
(b) relaying frames generated in a link layer in the reverse direction of the unidirectional link when the unidirectional
link is sensed in (a); and
(c) removing a repeated frame from among the relayed frames in (b), and providing unidirectional link connectivity in the
link layer to an upper layer through a filtering process using broadcasting and residual power information,
wherein said providing unidirectional link connectivity comprises:
comparing the residual power information included in the repeated frame with the residual power information calculated at
each mobile node, and when the residual power information of the mobile node is greater than the residual power information
in the repeated frame, allowing the repeated frame to reflect the residual power information to a generation of back-off time
so that the mobile node with high residual power relays the corresponding frame in advance.
