Energy Cooperation in Energy Harvesting Communications [PDF]
IEEE Transactions on Communications, 2013 In energy harvesting communications, users transmit messages using energy harvested from nature during the course of communication. With an optimum transmit policy, the performance of the system depends only on the energy arrival profiles. In this paper, we introduce the concept of energy cooperation, where a user wirelessly transmits a portion of its ...
