Abstract

The invention discloses a method for autonomous navigation and resource scheduling of an unmanned aerial vehicle in a wireless self-powered communication network, comprising the following steps: S1, determining a network model, a communication mode, and a channel model; S2, transmitting downlink wireless power and uplink wireless information Carry out modeling, and determine the optimization target expression and its constraints; S3, analyze the optimization problem, and model the optimization problem as a Markov process; S4, determine the network communication protocol and the UAV flight decision model; S5, define the neural network Network input state, UAV output action and reward function; S6, solve the optimization problem according to the deep reinforcement learning algorithm. The present invention not only realizes the energy supply to multiple ground devices, but also takes into account the wireless self-powered communication network by jointly designing three parts: the flight track of the drone, the selection of the ground equipment, and the communication mode with the ground equipment. Maximizing average data volume across multiple devices in a self-powered communication network.

Description

Autonomous Navigation and Resource Scheduling Method for Unmanned Aerial Vehicles Based on Wireless Self-Powered Communication Network technical field The invention belongs to the unmanned aerial vehicle energy supply communication network technical field, be specifically related to a kind of wireless self-powered communication network UAV autonomous navigation and resource scheduling method. Background technique [0002] Wireless sensor networks (WSNs) can be used to collect information about the surrounding environment. devices in wireless sensor networks The power of the sensor is limited. When it is exhausted, the sensor is charged by artificial means or traditional ground communication network. Electrical efficiency is very low. While radio frequency (RF) based energy harvesting (EH) can be viewed as extending the use of energy-constrained sensor devices An expected scheme of lifespan. Wireless Power Transfer (WPT) via RF radiation can provide low-power IoT dev...
