Energy Harvesting Technique Utilizing Resource Allocation Algorithm in 5G Wireless Channel

Abstract

The technology utilized in Energy harvesting from wireless channels of cellular communication is one of the critical aspects of future generation of cellular telecommunication, as it will be one of its alternatives for conserving power, by transmitting power to devices through the cellular networks. There have been numerous techniques that were proposed in 5G cellular technology for sustainability and enhancing the lifespan of centralized power sources in mobile and future IoT devices. Throughout this research paper, a literature review of the main current advancements of EH technology and SWIPT techniques will be presented as well as its achievements. An implementation of one of the Energy Harvesting techniques which is the SWIPT, in a cooperative relay scenario is presented in this paper and it is applied with a proper simulation tool. The simulation will mainly be implemented in MATLAB, which is divided into several functions computing the essential primary values for the proposed EH network. Firstly, the relay scenario that comprises a base station and two receivers with one receiver acting as a relay station while the other act as the final receiver for both transmissions. Secondly, the SWIPT technique is implemented in the Relay stations, where the AF protocol is utilized. Finally, the last receiver will receive both signals which represent the information decoding and the EH signals from the relay stations. The evaluation of the simulation results will be discussed in the final stages of the research. The outcome of this research will be the simulation results in which the estimation of the EH efficiency is evaluated based on two factors including; the number of EH subcarriers in the final receiver, and the average allocated power for EH transmission received by the final receiver. The idea behind this research paper was to search for an efficient method to harvest energy from the next nominated waveform of the 5th generation mobile communication OFDM. The anticipated outcome of this paper is beneficial in minimizing the cellular operation cost, extending the user equipment (UE) battery life, and creating an overall conserving green communication.
