Abstract
This paper presents a survey on energy harvesting (EH) wireless communication networks focusing on channel capacity, transmission schemes, and power optimization. While many network researchers focus on energy management policies addressing the intermittency and randomness of the EH processes, but the channel capacity, and transmission power optimization have not been fully explored yet. In this paper, we provide a review and analysis of channel capacity, offline and online transmission schemes, and power optimization from an information theory perspective. By reviewing and analyzing wireless networking literature, we found that EH is a technologically feasible and economically viable paradigm for cost-effectiveness in the design and deployment of next-generation wireless networks. Finally, we identify open research problems and future research directions in the emerging field of EH wireless networks. We expect this study to stimulate more research endeavors to build energy-efficient scalable next-generation wireless network systems.
Highlights
The exponential growth of wireless networks has highlighted the issue of energy consumption into sustainability and operating expenditure (OPEX) perspectives
In the review of literature, we mainly focused on aspects of channel capacity, transmission schemes, and power optimization in the context of energy harvesting (EH)
We examine a mathematical abstraction for energy harvesting devices (EHDs) that briefly introduces key concepts needed for the subsequent discussion and analysis
Summary
The exponential growth of wireless networks has highlighted the issue of energy consumption into sustainability (e.g., reducing carbon footprint) and operating expenditure (OPEX) perspectives. Harvesting energy from natural and ambient sources is a promising means of increasing energy efficiency and improving sustainability in wireless communication systems. Energy harvesting devices (EHDs) are of great interest in the contexts of energy efficiency in wireless communication networks. Various alternative energy sources such as solar, vibrational, thermoelectric, and electromagnetic can be harvested to power EHDs. EHDs facilitate perpetual operation and self-sustainability as far as energy efficiency is concerned [4]. The additional constraints due to the inherent intermittent and stochastic nature of the energy harvesting process introduce novel dimensions of uncertainty to the wireless communication problem. The research methodology we adopted in the literature review is discussed
