Power Scavenging for Strengthening the Life Cycle of Cooperative Devices in Correlated Hybrid Fading Environment

Abstract In next-generation wireless communication networks, end users demand higher throughput, improved reliability, and lower energy consumption for battery-operated devices. To improve the reliability and throughput of next-generation communication, drones are integrated with cooperative communication (CC), known as drone-assisted CC (DACC) systems. However, to address energy consumption in battery-operated devices, a power scavenging (PSV) scheme is proposed for drones in a DACC system within a hybrid correlated fading environment. For obtaining the PSV scheme, a statistical power splitting factor (PSF), is used at the drone in DACC systems. However, at a particular drone height and environmental parameters, the statistical PSF is chosen by using the probability of a line-of-sight (LoS). The performance of the proposal is calculated by developing the expressions of an outage probability and rate over the correlated hybrid fading environment. The algorithm for determining the rate and outage probability for the proposal in a correlated hybrid channel environment is developed. The outcomes of this research show that using PSV in DACC extends the network longevity. Our findings are useful in a crisis when drones with limited battery life are sent to assist in areas where natural catastrophes have disrupted cellular links to base stations.
