Wireless Transmission of Solar Power
The Solar Power Satellite (SPS) is an energy system that collects solar energy in the upper atmosphere and transfers it to the ground. It has been seen as one of the best ways to alleviate the problem of future electricity needs. In the times to come, wireless power transmission will be used as it requires less maintenance and numerous other benefits ...

On the downlink throughput capacity of hybrid wireless networks with massive MIMO
In this paper, the entire network model is a hybrid wireless network model in which each base station is connected to each other via a wired link. On this basis, we place a large number of antennas (massive MIMO) at each base station to serve a single ...

Imbalanced Data Classification for Multi-Source Heterogenous Sensor Networks
Most of the traditional classification algorithms are based on the uniform distribution of samples, and the effect is not ideal when dealing with such data, which mainly shows that the classification results incline to the majority class.

Wireless power transmission technologies
The article consists of three parts. The analysis of existing technologies of wireless power transfer (WPT) is carried out in the first part. It is noted that one of the factors that determines the choice of one or another WPT technology is the distance over which the power is transmitted and the type of electromagnetic (EM) energy used. The essence of
