Abstract

The invention provides a resource allocation method of an unmanned aerial vehicle assisted wireless power supply Internet of Things, which can realize optimal resource allocation of an unmanned aerial vehicle and a wireless node in a wireless power supply Internet of Things system and improve the system performance. The method comprises the following steps: constructing a wireless power supply Internet of Things system consisting of an unmanned aerial vehicle and wireless nodes; constructing a maximum profit function of energy transfer of the wireless nodes, and solving the constructed profit function to obtain optimal transmitting power from the wireless nodes to the unmanned aerial vehicle; enabling the unmanned aerial vehicle to construct an unmanned aerial vehicle and wireless node resource allocation model based on a dynamic game in the wireless information transmission and wireless power transmission process with the goal of maximizing the energy transmission income; and according to the constructed unmanned aerial vehicle and wireless node resource allocation model based on the dynamic game, obtaining a Nash equilibrium solution by utilizing Berman dynamic programming, and taking the Nash equilibrium solution as an optimal allocation strategy of wireless energy transmission resources in the wireless power supply Internet of Things system. The invention relates to the field of wireless power supply Internet of Things.

Description

technical field [0001] The present invention relates to the field of wireless power supply Internet of Things, in particular to a resource allocation method for UAV-assisted wireless power supply Internet of Things. Background technique [0002] The Internet of Things (IoT) plays an important role in the next generation of mobile communications and wireless networks and can be applied to services. With the advent of the Internet of Everything era, data transmission is becoming more and more intensive, and the amount of information exchange is also increasing. Therefore, communication technology with greater bandwidth, higher speed, lower latency and lower energy consumption is an important guarantee to ensure the popularity of the Internet of Things. Due to the limited energy of most wireless devices in IoT, even with low power density and high cost, the development and application of IoT are facing unprecedented severe challenges. How to provide sustainable energy for wir...
