Energy Harvesting Wireless Communications: A Review of Recent Advances

Abstract—This paper summarizes recent contributions in the broad area of energy harvesting wireless communications. In particular, we provide the current state of the art for wireless networks composed of energy harvesting nodes, starting from the information-theoretic performance limits to transmission schedul-ing policies and resource allocation, medium access, and net-working issues. The emerging related area of energy transfer for self-sustaining energy harvesting wireless networks is considered in detail covering both energy cooperation aspects and simulta-neous energy and information transfer. Various potential models with energy harvesting nodes at different network scales are re-viewed, as well as…
