In order to solve the reduced reliability problem caused by nodes failure in the wind turbine condition monitoring system

a node routing repairing algorithm based on alternative father nodes and brother nodes (RRA-FB) is proposed. When the monitoring data encounters failure nodes in the process of transmission

nodes waiting for data transmission will query and obtain information of their parent nodes and brother nodes

and use their effective parent nodes in preference to substitute failure nodes. Only if all the parent nodes have failed are their effective brother nodes enabled to substitute failure nodes

to refresh transmit data for improving the route reliability of monitoring system. Simulation analysis shows that RRA-FB can significantly improve the success rate of data transmission for the wind turbine condition monitoring system.
