Green Communication for Wireless Cooperative Networks: A Survey

Abstract

For next-generation wireless networks, radio frequency (RF) energy transfer and harvesting emerged as a viable solution to the energy-constrained nodes. In this paper, comprehensive literature review on recent research progress in wireless-powered cooperative network (WPCN) with RF energy harvesting capability is presented. First, overview of green communication with distinct classification and protocols is given. Further, comparison of half-duplex (HD) and full-duplex (FD) relaying methods is presented. Finally, open research challenges are envisioned.
