Recent emphasis on green communications has engendered great interest in the investigations of energy harvesting communications and networking. Energy harvesting from ambient energy sources can potentially reduce the dependence on the supply of grid or battery energy, providing many attractive benefits to the environment and deployment. However, unlike the conventional stable energy, the intermittent and random nature of the renewable energy makes it challenging in the realization of energy

Extensive research studies have been carried out in recent years to address this inherent challenge from several aspects: energy sources and models, energy harvesting and transmission protocols, energy scheduling and optimization, implementation of energy harvesting in cooperative, cognitive radio, multi-user and cellular networks, etc. However, there has not been a comprehensive survey to lay out the complete picture of recent advances and future directions. To fill such a gap, in this article, we present an overview of the past and recent developments in these areas and highlight a number of possible future research avenues. Index Terms-Energy harvesting, cooperative networks, cognitive radio networks, multi-user interference networks, cellular networks.
