Abstract

The invention provides a resource allocation method in a wireless power supply mobile edge computing system. The optimal resource allocation in the wireless power supply mobile edge computing system can be realized. The method comprises the following steps: constructing a wireless power supply mobile edge computing system; determining a differential equation representing the energy state change of the AP and the wireless device in the wireless energy transmission and calculation unloading process; determining a revenue function of the AP and the wireless device according to the Stackelberg game; and according to the determined differential equation representing the energy state change of the AP and the wireless equipment and the profit functions of the AP and the wireless equipment, determining the optimal transmission power of wireless energy transmission of the AP and the optimal proportion of a calculation task unloaded to the AP by the wireless equipment by utilizing a Bellman dynamic programming principle. The invention relates to the field of Internet of Things.

Description

technical field [0001] The present invention relates to the field of the Internet of Things, in particular to a resource allocation method in a wireless power supply mobile edge computing system. Background technique [0002] The Internet of Things (IOT) is a physical Internet that uses various information-aware devices to sense real-time data from the environment and communicate between devices and people. The application of the Internet of Things can effectively improve the level of social intelligence, thereby greatly promoting people's lives. One challenge with connected devices is the issue of energy constraints. The rapid development of IoT technology has led to an exponential growth of wireless devices. Most wireless devices in the Internet of Things are energy-limited and computing-resource-limited devices that do not have a steady supply of energy. How to reduce energy consumption, reduce computing tasks, and provide sustainable energy for wireless devices has be...
