The network topology generation method can reduce a network delay fairly and minimally, upon generating a new network topology, by considering a network condition in a physical layer. The network topology generation method includes establishing a virtual connection between the new node and each of the plurality of nodes; calculating an average metric value of routes from the new node to the plurality of nodes via each of the virtual connections; and establishing a connection between the new node and the node to which the virtual connection having the smallest average metric value is established, so that the new node joins the network.

Network node and associated methodology of expanding a network topology through peer selection

A node includes a manager configured to manage the hash value of the node and the hash values of adjacent nodes, and a calculator configured to calculate an insertion position of a new entry node in a ring network, based on the hash value of the new entry node, the hash value of the node and the hash values of the adjacent nodes.
