Patent ID: 7349370

Claim:
A method for managing a neighbor node in a mobile ad hoc network environment, comprising: receiving a packet that is periodically broadcast from a neighbor node; measuring quality of a link with the neighbor node through the received packet; and managing the neighbor node in a first node group or a second node group according to the measured link quality; comparing the measured link quality with a second threshold value when, as a result of searching, the neighbor node is found in the first node group; maintaining the neighbor node in the first node group when the link quality is found to be higher than the second threshold value; and classifying the neighbor node into the second node group when, as a result of the comparison with the second threshold value, the link quality is found to be lower than the second threshold value, wherein managing the neighbor node comprises: searching for the neighbor node in the first node group; comparing the measured link quality with a first threshold value when the neighbor node is not found during the search; classifying the neighbor node into the first node group when the link quality is higher than the first threshold value; and classifying the neighbor node into the second node group when the ling quality is lower than the first threshold value.
