Claim:
1. A node device comprising: a memory; and a processor coupled to the memory and configured to: receive first data communicated between the node device and adjacent node devices that are adjacent to the node device; calculate a link cost between the node device and each of the adjacent node devices, based on the first data; correct the link cost by adding a first cost to the link cost, the first cost depending on communication performance of the each adjacent node device, the first cost being held as a predetermined value by the each adjacent node device and being included in the first data by the each adjacent node device that has transmitted the first data to the node device; store in the memory, in association with each of the adjacent node devices, a first integrated link-cost value obtained by adding the link cost corrected by the corrector to a second integrated link-cost value, the second integrated link-cost value being obtained by summing up link costs along a communication route from a destination node device serving as a final destination of second data to the each adjacent node device; and transmit, to the adjacent node devices, the first data including the first integrated link-cost value and a second cost depending on communication performance of the node device.
