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 according to dual preferences. According to the method, the service life of the wireless sensor network is prolonged by setting dual preferences for the unmanned aerial vehicle and considering the total charging amount and the residual electric quantity of the sensor nodes, and the design of a distributed resource allocation algorithm is completed through bidirectional selection of the unmanned aerial vehicle and the sensor nodes, so that reasonable allocation of electric quantity resources is realized.
本发明公开了一种面向无线传感器网络的无人机充电分配方法及设备,方法包括:设置无人机和传感器节点之间的选择偏好,传感器节点的偏好为选择有效充电量最大的无人机,无人机第一重偏好为选择距离更近的传感器节点充电,在第一重偏好基础上,无人机第二重偏好为选择剩余电量最低的传感器节点充电;需要充电的传感器节点优先向能够提供最大有效充电量的无人机发起请求,接收到不止一个充电请求的无人机根据双重偏好选择传感器节点。本发明通过对无人机设置双重偏好兼顾充电总量与传感器节点剩余电量以延长无线传感器网络的使用寿命,并通过无人机与传感器节点的双向选择完成分布式资源分配算法的设计,实现电量资源的合理分配。
