Abstract
A transmission quality estimation method estimates a transmission quality of a target path. The method includes: storing path transmission quality values that respectively indicate transmission qualities of paths established between adjacent nodes in a first storage; storing a node transmission quality value that indicates a transmission quality of a node device in a second storage; estimating a transmission quality of the target path based on the path transmission quality values stored in the first storage and the node transmission quality value stored in the second storage; calculating the node transmission quality value based on the estimated transmission quality of the target path; and updating the node transmission quality value stored in the second storage using the calculated node transmission quality value.
