Abstract
A data routing method and system, the data routing method including: locating a destination node using a destination locating packet; establishing a preliminary route including anchor nodes based on a route where the destination locating packet is transmitted to the destination node; determining a link cost between neighbor nodes of each of the anchor nodes, and also between the anchor nodes and the neighbor nodes of each of the anchor nodes; generating minimum cost information with respect to a route consuming a minimum cost from the destination node to a source node using the link cost; and forming a data route from the destination node to the source node using the minimum cost information.
