PROBLEM TO BE SOLVED: To maintain a high transmission rate even when rainfall strength is high.SOLUTION: A radio network system comprises a plurality of nodes for performing radio communication using a frequency band where communication quality is deteriorated by rainfall, and reconstructs network topology according to deterioration prediction of the communication quality. The radio network system comprises: a master node 3 which predicts whether or not communication quality in any radio link is deteriorated by occurrence of a factor affecting communication quality of each radio link, and gives an instruction to add a radio link not passing through a radio link whose communication quality's deterioration is predicted and delete the radio link whose communication quality's deterioration is predicted when a result of the prediction shows that communication quality of any radio link is deteriorated; and a plurality of slave nodes 5 for performing addition or deletion of the radio links according to the instruction of the master node. |
