Article
Full-text available
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 pa...

In the practical implementation of wireless powered communication network (WPCN) project, the energy consumption is an important factor to evaluate the performance and efficiency of the communication. In this project, a UAV enabled WPCN acts as a hybrid access point to handle multiple ground terminals (GT’s) in an uneven plane. The ground terminals...

A serious drop in ensuring the water quality in the distribution system is a factor that affects public health. This could lead to increase in biological and non-biological contents, change in colour and odour of the water. These contaminants cause a serious threat to the whole water ecosystem. The conventional methods of analyzing the water qualit...

Question
I am currently doing my research where I am planning to work with antenna arrays integrated into a UAV for energy transfer. So, if I am using a 4x4 planar array(dipole elements) to create a beam.
1. How could I calculate the coverage of a beam.
2. What is the maximum tilt I can perform to steer the beam in order to charge some of the ground nodes? It will be really a great help if somebody could clarify this. Thanks in advance
