Abstract

Disclosed is a packet routing method in an ad-hoc network. The method includes periodically calculating a link stability with respect to each neighbor node by means of the number of beacon frames lost within an update period for each neighbor node, updating the calculated link stability in the neighbor node table; identifying a neighbor node which is closer to a destination node of a received packet than the node when the node itself does not correspond to the destination node; and transmitting the received packet to the identified neighbor node when the identified link stability of the neighbor node is greater than or equal to a threshold value.
