Unmanned aerial vehicle charging distribution method and equipment for wireless sensor network

The invention discloses a wireless sensor network-oriented unmanned aerial vehicle charging distribution method and device, and the method comprises the steps: setting a selection preference between an unmanned aerial vehicle and a sensor node, the preference of the sensor node being to select an unmanned aerial vehicle with the maximum effective charging amount, the first preference of the unmanned aerial vehicle being to select a closer sensor node for charging, and the second preference of the unmanned aerial vehicle being to select a closer sensor node for charging; on the basis of the first preference, the second preference of the unmanned aerial vehicle is that the sensor node with the lowest residual electric quantity is selected for charging; the sensor node needing to be charged preferentially initiates a request to the unmanned aerial vehicle capable of providing the maximum effective charging amount, and the unmanned aerial vehicle receiving more than one charging request selects the sensor node ac
