A Rescheduling Method of Drone Flights under Insufficient Remaining Battery Duration

A rescheduling method is proposed for drone flights to handle insufficient remaining battery duration during flights. The flight of drones is usually affected by strong winds and/or moving obstacles. To keep a planned flight path, drones are imposed to consume more battery to overcome these unexpected external events. It results in insufficient battery duration, which cannot guarantee the safe return of drones and/or the fulfillment of the assigned mission (demands). Hence, the rescheduling method is presented to ensure the safe return of drones and minimize the unmet demand.
