Unmanned aerial vehicle assisted backscatter communication device and resource allocation control method

Abstract

In existing backscatter communication research, the communication performance difference of backscattering equipment at different positions in the system is large, we face the serious fairness problemin order to overcome the defects of existing research,the invention provides an unmanned aerial vehicle auxiliary backscatter communication device and a resource allocation control method. The control assembly comprises a data acquisition module, an unmanned aerial vehicle control module, a track control module, a communication control module and a working mode control module. The backscatteringequipment assembly comprises a ground control module, a working mode selection module, an energy receiving control module, a signal reflection control module and an energy collector. According to theinvention, the unmanned aerial vehicle is used as a control center to transmit and receive an information command to the equipment, and the backscattering equipment collects energy or reflects a signal to transmit information. The flight path is optimized by utilizing the flexible mobility and operability of the unmanned aerial vehicle, so that the distance between the unmanned aerial vehicle andthe sensor is effectively shortened, and the throughput of a communication system is improved.

Description

technical field [0001] The present invention relates to the field of unmanned aerial vehicle (UAV) technology application and backscatter communication (Backscatter Communication) field emerging in recent years.

Problems solved by technology

[0008] In the existing backscatter communication research, the traditional design is generally based on a fixed base station, which makes the communication performance of backscatter devices at different positions in the system vary greatly, and faces serious fairness problems

The wireless communication channel between the ground base station at a fixed location and the device is usually fading, and the wireless communication channel will deteriorate with the distance between the base station and the backscattering device
