Wireless sensor network repairing method based on unmanned aerial vehicle

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 inven
