Energy Efficient Communication Design in UAV Enabled WPCN Using Dome Packing Method in Water Distribution System

Abstract

The water distribution system has deployed several low-power IoT devices on an uneven surface where battery power is a major concern. Therefore, this paper focuses on using a UAV-enabled wireless powered communication network capable of directing energy to a target location and using it for communication, thereby reducing battery issues. In this paper, a static optimization was applied to find the initial height values using 3D clustering and beamforming method and dynamic optimization using extremum seeking method was applied to find the optimized height. The optimized height values were calculated and Travelling Salesman Problem (TSP) was applied to create the trajectory of the UAV. The overall energy consumption of the UAV was minimized by integrating dynamic optimization and dome packing method, which can find an optimal position and trajectory where the UAV will be hovering to direct energy and collect data. Moreover, we also minimized the total flight time of the UAV.

Water Quality Sampling and Multi-Parameter Monitoring System Based on Multi-Rotor UAV Implementation

“…To effectively improve the efficiency of water quality sampling, path planning for UAVs is crucial [32,33]. During the path planning process, factors such as water body characteristics, distribution of sampling points, and flight safety need to be considered in order to ensure that UAVs can efficiently cover the target area and collect an adequate number of water quality samples [34].…”
