Joint Trajectory and IRS Phase Shift Optimization for Dual IRS-UAV-Assisted Uplink Data Collection in Wireless Sensor Networks
Abstract
Highlights
- This paper designed a completely new model of dual IRS-UAV-assisted communication.
- This paper presents a new trajectory optimization algorithm.
- Compared with the traditional single IRS-UAV-assisted communication model, the newly proposed model can significantly enhance the sum rate of the communication system.
- The proposed new algorithm can effectively address the non-convexity issue in optimization problems.
