摘要

PROBLEM TO BE SOLVED: To design a low-order node so as to accommodate the low-order node on a ring network in such a manner that an average connectable number or a total connectable probability is represented by a formula and optimized on the basis of a model corresponding to regional disaster attack.;SOLUTION: A first evaluation scale defined by using a probability for all the low-order nodes within the ring network to be connectable with a node (j) via a node (k) on the ring network is calculated by using positional information items stored in storage means. A second evaluation scale defined by using a probability for all the low-order nodes within the ring network to be connectable with the node (j) via a node k' on the ring network is calculated by using positional information items stored in the storage means. An accommodation node is determined by comparing the first evaluation scale and the second evaluation scale with each other.;COPYRIGHT: (C)2015,JPO&INPIT
