The invention discloses a minimization information age-based island clustering and unmanned aerial vehicle trajectory planning method, which comprises the following steps of: clustering all islands covered by an unmanned aerial vehicle assisted wireless energy supply communication network according to hovering point positions of unmanned aerial vehicles on the islands to obtain clustering results of all islands; determining a final clustering result and a hovering point access sequence in each cluster according to the limited battery capacity constraint of the unmanned aerial vehicle in the cluster, the task completion of the unmanned aerial vehicle, the flight back of the hybrid access point for unloading data, and the average information age constraint received by the hybrid access point, and finally determining the hovering point access sequence in each cluster according to the final clustering result. And sequentially flying each cluster according to the access sequence of the hovering points in the cluster. According to the technical scheme of the invention, the average information age of the data received by the hybrid access point in the unmanned aerial vehicle assisted wireless energy supply communication network is reduced.

    本发明公开了一种基于最小化信息年龄的岛分簇和无人机轨迹规划方法,根据无人机在岛上的悬停点位置,对无人机辅助无线供能通信网络覆盖的所有岛进行分簇处理,得到所有岛的分簇结果,根据簇内的无人机有限电池容量约束和无人机完成任务,飞回混合接入点卸载数据,混合接入点接收的平均信息年龄约束,确定最终分簇结果和每个簇内的悬停点访问顺序,最后按照最终分簇结果,依次对每个簇按照簇内的悬停点访问顺序进行飞行。本发明技术方案降低了无人机辅助无线供能通信网络中混合接入点接收数据的平均信息年龄。
