Repair method of wireless sensor network based on UAV

Abstract

The invention discloses a wireless sensor network repairing method based on an unmanned aerial vehicle. The method comprises the following steps: periodically collecting the state information of network nodes; classifying the network nodes into three modes: a normal state, a failed state and a critical state; selecting the nodes in the failed state and the critical state; providing secondary deployment nodes for overcoming corresponding reasons; putting the secondary deployment nodes in a case of the unmanned aerial vehicle; when the unmanned aerial vehicle takes off, hovering the unmanned aerial vehicle at corresponding position according to the flight path, and delivering the network nodes; after current deployment is finished, uploading the deployment information, and enabling the unmanned aerial vehicle to fly to next position; after all deployment is finished, enabling the unmanned aerial vehicle to return to base, to finish the network repairing deployment. According to the method disclosed by the invention, according to the failure reason of traditional network node repairing method, the risk of further failure of the nodes is reduced through secondary deployment of targetednetwork nodes; meanwhile, by adopting the unmanned aerial vehicle to perform node deployment, the cost can be lowered, and the labor intensity is reduced.
