Abstract

The invention discloses a mobile data acquisition method based on an unmanned aerial vehicle. The method comprises the following steps: establishing at least one alternative charging node set of a wireless sensor network; generating a target network topology of each alternative charging node set according to an expected life equalization principle, and calculating expected energy consumption of the target network topology; establishing a collaborative revenue function based on the expected energy consumption, and constructing and solving a linear programming problem to generate a collaborative revenue and charging duration distribution scheme corresponding to each alternative charging node set; and selecting a target network topology and a charging duration distribution scheme corresponding to the alternative charging set with the maximum cooperative benefit to control the unmanned aerial vehicle to perform mobile data acquisition. The mobile data acquisition method is designed based on the life expectancy equilibrium strategy, then the linear programming problem with maximization of the collaborative income as the optimization target is established by considering the charging efficiency and the communication energy consumption, the optimal charging duration distribution strategy is generated, the charging efficiency and the data acquisition energy efficiency are considered, and the working efficiency of the unmanned aerial vehicle is remarkably improved.

Description

technical field [0001] The present invention relates to the field of wireless sensor networks, in particular to a method, device and terminal for mobile data collection based on unmanned aerial vehicles. Background technique [0002] The Internet of Things is widely used in various large-scale systems to help them realize remote environmental perception. Among them, the wireless sensor network composed of a large number of sensors is mainly used in the collection of environmental data of the Internet of Things. In many application scenarios such as high-voltage transmission lines, cable trenches, substations, etc., the wiring cost is high, and it is difficult to provide wired and stable power supply for the sensor, and the battery capacity of the sensor is limited by the size and is usually not easy to replace. Therefore, how to improve the energy efficiency of the network and design a reliable energy supplement scheme has always been a key issue in this field. [0003] Acc...
