Abstract
A method for determining time to live (TTL) of a path of a node including receiving a routing control packet, which includes a first link quality indicating a link quality of a path from the neighbor node to a source node transmitting the routing control packet, from a neighbor node of the node, acquiring a third link quality indicating a link quality of a path from the node to the source node according to a second link quality indicating a link quality of a path from the node to the neighbor node and the first link quality, and determining the TTL of the path from the node to the source node according to the third link quality may be provided. Accordingly, the TTL of the path can be determined more accurately according to a link quality of the path, thereby contributing to ensuring performance and stability of a routing algorithm.
