Joint Optimization Method of Spectrum Resource for UAV Swarm Information Transmission

Abstract

For the problems brought by malicious interference in the unmanned aerial vehicle (UAV) swarm network, we establish a cluster-based UAV swarm information transmission model. We mainly consider four aspects: cluster head selection, channel allocation, power allocation and UAV position. In order to improve the backhaul information rate of UAV swarm, we propose a joint optimization method of spectrum resource with the goal of maximizing the sum throughput of the cluster head UAV. We decompose the original mixed integer nonlinear programming (MINLP) problem into multiple sub-problems based on the block coordinate descent (BCD) technique, and then solve them based on convex optimization and successive convex approximation (SCA) technique. Simulation results show that the proposed method can obtain the spectrum resource optimization strategy of UAV swarm information transmission, reduce the impact of malicious interference, and effectively improve the backhaul information rate of UAV swarm.

A Robust Scheme for RIS-Assisted UAV Secure Communication in IoT

“…Considering the limited spectral resources and energy constraints of IoT devices, fixed terrestrial base stations (BSs) face significant challenges in providing services to an increasing number of IoT devices and networks. Fortunately, unmanned aerial vehicles (UAVs) have been widely discussed for their ability to quickly deploy as air relays to boost the capacity and coverage of existing terrestrial networks and enhance the quality of wireless communication [3][4][5]. Due to the heterogeneity and geographical dispersion of IoT devices, several security issues have arisen.…”
